Solaris (Sonic)

"That body of light is the sign of a super-dimensional life-form. Standard attacks won't work on him. He eats dimensions for lunch!"

- Dr. Eggman about Solaris. "I'm Mephiles, Mephiles the Dark! What, did you forget me?"

- Mephiles the Dark "Eternal Sun! The Living Flame that has been entrusted to the royal family! Fall into slumber with my soul, Iblis! You cursed Flames of Disaster!"

- Silver the Hedgehog about Iblis.

Solaris, also known by his halves Mephiles the Dark and Iblis, the Flames of Disaster is the main villain of the 2006 Sonic the Hedgehog videogame. As Mephiles, he serves as the main antagonist of Shadow's story, the secondary villain of Silver's story, and a minor antagonist in Sonic's story. As Iblis, he serves as the main villain of Silver's story and a minor antagonist in both Sonic and Shadow's stories. Solaris himself serves the main villain of the Last Story, as well as the game's final boss.

Solaris is an all-powerful, immortal extradimensional being who is worshipped by the Kingdom of Soleanna as a sun god, whose goal is to erase all existence by devouring all timelines. His two halves, Mephiles (his consciousness and intelligence) and Iblis (his raw power), were accidentally created during the ill-fated Solaris Project. Mephiles took Shadow's form after being resurrected and never used anybody else's appearance. Mephiles is the mind and will of Solaris while Iblis is the raw power, and they eventually fuse back together into Solaris and are later defeated.

Solaris's conscious mind, Mephiles, was voiced by Dan Green, who also played the voice of Dark Yugi in the Yu-Gi-Oh! franchise.

Mephiles
Mephiles the Dark was born from the "Solaris Project", an experiment conducted by the government of Soleanna; officially an energy research program, the project's true goal was to harness the power of Solaris and give humanity control over the flow of time itself. However, the project ended in a disaster that split Solaris into two beings; Mephiles and Iblis, both of whom were really powerful and were now escaping the underwater lab the explosion happened in. After he escapes in an formless ooze, he is sealed in the Scepter of Darkness by Shadow the Hedgehog, who travelled through time to 10 years before the events of the 2006 Sonic game.

In the present, Dr. Eggman got hold of the Scepter and Shadow went to steal it, so that G.U.N. could have it. At a rendezvous point with Rouge the Bat at the original castle of the Soleanna royal family, Eggman appeared and brought robot henchmen to steal the Scepter back. He attacks Rogue while she tries to get away, but is saved by Shadow. The Scepter on the other hand fell and broke, damaging Eggman's robots. Mephiles (as a cloudy being) flew out, killed the robots, scared Eggman away and landed into the ground, sucking Shadow's own shadow out and using it to become a demonic version of Shadow. He sends Shadow and Rouge into the future with his new time-traveling powers after he realizes that Shadow does not know who he is.

While there, Mephiles somehow found out that Princess Elise the Third had Iblis sealed in her body since the Solaris Project explosion, and the only way to release the demon was to make her cry. She would later also have visions of a frightening future where Iblis destroys everything should he be ever awakened. To accomplish this, he tells Silver the Hedgehog and Blaze the Cat that Sonic the Hedgehog was the cause of Iblis being released into the future (as it has now destroyed most of the world by this point), which led to the destruction of their world. Sonic was, thus, referred to as the "Iblis Trigger". He sends the two back in time, making them believe that killing Sonic would save the future.

Mephiles later tells Shadow (who is still in the future) that the world, and eventually E-123 Omega, will betray him in the future, and asks him to join him in order to punish the world of humanity. First, he explains that when Iblis came around to cause the apocalypse, the world would search for someone to blame ("A search for the guilty. Who did this, you may ask?"), and people used this as an excuse to lock Shadow (in the future, at least) in an energy cage until the end of time. Shadow, however, refused to believe and join Mephiles, and fights him as he takes the form of a crystalline hedgehog while E-123 Omega eventually pops in and aids Shadow.

Mephiles retreats to the present, and somehow transforms back into his Shadow form on the way in order to keep manipulating Silver and Blaze. He tells them that Sonic is at the terminal station, and it is now or never if they want their world to be safe. Later, he encounters Omega at Wave Ocean, who starts to shoot him. After getting shot, Mephiles reveals that Omega himself was created to defeat Shadow in the future. Enraged by this, Omega switches to his machine guns, and shoots Mephiles again. As Mephiles started to fade away, he laughs evilly. After Omega told Shadow about Mephiles' statement, Shadow feels hurt and walks away. Meanwhile, Shadow, Omega, and Rouge encounter Mephiles once again at the Dusty Desert, now having discovered his plans to obtain seven Chaos Emeralds and fuse with Iblis, and fight him in a temple, all while he taunts Shadow and sends clone after clone at him. After they defeated him, Shadow tried to imprison Mephiles with their new Scepter of Darkness, but Mephiles proved to be immune to this imprison and pushes Shadow and his partners away. He then uses the Chaos Emeralds to create a massive load of Mephiles clones, enough to take on an army of Eggman's robots. He then boasts to Shadow that he cannot defeat him, and asks why he is even bothering to protect a world that will eventually turn against him. Shadow responds by saying, "If the whole world decides to become my enemy, then I will fight like I always have", and he removes rings on his wrists that unleashes a super-power that allows him to bulldoze through the army until it becomes a puddle of goo.

After either Mephiles escaped or survived the battle with Shadow, he finds the purple Chaos Emerald (despite possessing it previously to deceive Silver), uses it to warp to Sonic and Elise's location shortly after they escape Eggman's exploding Egg Carrier, blinds them with the Emerald's powers, and impales Sonic through the back with an energy beam, killing him instantly. Elise cries over his death and, as a result, releases Iblis (as a mere fireball). With this done, Mephiles took his Emerald and used it to fuse with Iblis and transform into Solaris, and release a bright light that engulfs the Soleanna Castle Town and transports all the protagonists (and even Eggman) into a shattered dimension. It is also revealed here that his lie to Silver and Blaze about Sonic being the Iblis Trigger was actually a half-truth: Sonic is indeed the Iblis Trigger, but his death would not stop Iblis' resurrection, but it seems that his death would be the very event that would release Iblis from Elise's soul. The key to Iblis's freedom was an event that would cause Elise to become so consumed with despair or guilt that she would cry, and she had formed a very close (possibly even romantic) bond with Sonic.

Solaris tried to consume all existence while the protagonists go through the past levels in the game to get the Chaos Emeralds. Solaris sends black hole-like anomalies and evil monsters to stop them, but they got the Emeralds and revived Sonic. Solaris was then taken down by Super Sonic, Super Shadow and Super Silver all taking turns, which drops Elise and Sonic into a time-warp that sends them to when Solaris was only a measly flame. When Elise blew out the flame, Mephiles was erased from history and the game's events were actually part of an alternate timeline.

However, Mephiles later returned, as evidenced by his appearance in Sonic Runners and Iblis' survival in Sonic Generations, the latter which seems to imply the return of Mephiles as well.

Iblis
Iblis, also known as the Flames of Disaster, was the second half of Solaris, consisting of the entity's raw power. Like Mephiles, he was born from the Solaris Project when Solaris was split in two. The Duke of Soleanna sealed Iblis inside his daughter, Princess Elise, in order to prevent him from destroying the world. However, if Elise were ever to cry, her tears would release Iblis from within her.

In the future, Silver and Blaze fought against Iblis, but no matter how many times Silver defeated him, he would always survive, only reduced to a ball of fire from which he regenerated. Mephiles tried to manipulate Silver into going back in time and killing Sonic, claiming that Sonic would be the one to release Iblis, but his true intent was to release Iblis from inside Elise. After Silver defeated Iblis the final time, Blaze sealed him inside herself and presumably destroyed herself along with him. However, what happened next in the present would erase Iblis's future events from history.

To get Iblis out of Elise, Mephiles killed Sonic with a Dark Chaos Lance. Elise dropped down crying in despair, releasing Iblis. The two then joined up to become one, "Solaris the Timeweaver". Later, Elise revived Sonic using the Chaos Emeralds and one kiss, turning him into Super Sonic. He joins up with Shadow and Silver to defeat Solaris. After destroying Solaris, Elise was sent back to the past, where she put out the flame that would become Solaris, thus erasing Iblis and Mephiles from existence.

Solaris
Solaris initially existed as an apparently living flame which was praised and beloved by the citizens of the coastal city-estate/nation of Soleanna as their patron deity. Nothing is known about Solaris' origins, other that he had been "entrusted" to the Soleannean royal family ruling over Soleanna and its people at some point in the past and had remained under the protection of them and within the bowels of the former Soleannean royal palace in Kingdom Valley for an unpresented amount of time.

In the Soleannean culture, the Kingdom of Soleanna held an annual holiday called the "Soleanna Sun Festival" to honor their god as they celebrate with lights, fireworks, and ceremonial dancing. The final part of the festival begins and ends with members of the Soleannean royal family, accompanied by religious Soleannean priests in yellow hooded robes, offering prayers to Solaris with hopes of bright and prosperous years for Soleanna as they lit the city's treasured stone monument called the "Altar of Light" (also called the "Altar of Flame") in the centre of the city square.

During the reign of the Duke of Soleanna, the Duke prepared a temporal research program known as the Solaris Project to experiment on Solaris in the hopes of using his time control powers to allow humanity to correct its past sins (and also to allow himself and his young daughter, Princess Elise the Third, to see Elise's deceased mother once again). Once Solaris' flame had grown significantly large enough, the Solaris Project was initiated, leading to several experiments being performed on Solaris. However, during one such experiment, Solaris became unstable, ignoring the Duke of Soleanna's pleas and split into 2 evil entities: Iblis, the raw power and Mephiles, the cunning conscious mind. Mephiles was sealed into an artifact known as the Scepter of Darkness by the time-traveling Shadow the Hedgehog, while the Duke was forced to seal Iblis inside of Princess Elise's soul. Before dying from wounds caused by the accident, he told his daughter to grow up to be a strong queen who would never cry as doing so would destroy the seal on Iblis which is said to bring about the Day of Disaster upon its awakening.

Mephiles was eventually freed and he began plotting to reunite with Iblis. He made Princess Elise cry by killing Sonic the Hedgehog, thereby releasing Iblis and the two beings whose fusion empowered by the magical energy of the Chaos Emeralds, joined to form Solaris again. Solaris immediately plunged the world into darkness and prepared to devour time itself by consume all existing timelines. Before he could achieve this, however, he was defeated by a combined assault from Super Shadow, Super Silver and a resurrected Super Sonic, where the heroes and their allies managed to defeat Solaris by destroying his consciousness. Solaris' defeat reverted him back to his original form, the "Flame of Hope", and spirited Elise and Sonic back to before the fateful experiment. After some contemplation, Princess Elise chose to blow out the very radiant fire that would become Solaris and thus change history by erasing him completely from existence.

Mephiles
Mephiles appears in the Sonic Universe comics, set in the Archie Sonic continuity.

Issue 29
Mephiles has been captured by the Zone Cops and locked into the Zone prison due to his messing with the Zones. His powers were taken away due to the Bands placed around his arms.

During his time here he sat with Void in the cafeteria and talked to him, Mephiles noticed Scourge angrily walking away from the Destructix and wondered what was going on.

Issue 32
When Scourge and the Destructix managed to deactivate the Zones defenses. Mephiles attempted to escape from the prison. It is unknown whether or not he succeeded.

Iblis
Iblis is going to appear in an upcoming Comic, so it is likely Mephiles will return as well.

Solaris
In the Sonic the Hedgehog comic book series by Archie Comics, Solaris was initially hinted to have made an appearance in the comics' continuity by writer Ian Flynn, who confirmed that the events of Sonic the Hedgehog (2006) had occurred in the comics. Solaris was later officially revealed to have appeared in the comics in The Complete Sonic Comic Encyclopedia though it has yet to appear in the storyline. Much like in the game, Solaris was originally a flame which was split into Mephiles and Iblis during experiments conducted by the Duke of Soleanna and his researchers. Solaris was eventually restored due to the actions of Mephiles and prepared to destroy time, but was stopped, and eventually erased from existence by Sonic the Hedgehog and Princess Elise.

Mephiles
Mephiles is a cold-hearted and villainous demon, using lies and threats to turn friends against each other. He is shown to be extremely sadistic and destructive, as he gloats over how Omega will be the one to betray Shadow in the future and takes simple enjoyment over killing Sonic. He is manipulative and determined, yet never losing his composed temper once. He is also arrogant and views others inferior compared to him, due to his status as a god. He is also shown to be nihilistic, evidenced by his questioning Shadow as to why he even bothers fighting at all to protect humanity when they will inevitably persecute him later. He also craves destruction, right down to even time itself.

He is considered the most evil villain in the Sonic universe, as he does not have revenge as a motive nor does have a tragic backstory, not to mention the above mentioned desire to destroy everything. He is also considered one of the darkest villains with no redeeming qualms in the Sonic universe, largely for the same reasons.

Iblis
Iblis is a pure mindless creature, seeking nothing more but destruction. However, when Iblis reached to his third form, he seems to have gained some kind of focus when battling SIlver and Blaze for the final time.

Mephiles
"Drown in darkness!"

- Mephiles the Dark

Mephiles is capable of taking various forms by absorbing an individual's shadow, which resulted in his gaining his common form. Subtle differences are applied, however, such as a far darker shade of various colors, a pale complexion, and bestial green eyes. Besides actually taking on a form with someone's shadow, he also can grow stronger by absorbing shadows, especially if it comes from the same type of shadow as the being whose shadow he absorbed earlier outside of time. This is especially evident with his second encounter, where he managed to effortlessly escape imprisonment from another Scepter of Darkness due to his present self having gone back in time absorbing Shadow's shadow while the latter was sealing away Mephiles' past self.

Mephiles can manipulate and move through time with an ability similar to Chaos Control. Whether or not this was due to taking Shadow's form through his shadow or he had this power all along is debatable; however, being one half of the time god Solaris, the latter seems more probable. In addition, he has enough control over his abilities of time manipulation to separate pursuing enemies, as evidenced by how he managed to escape Omega and Shadow after their first fight in the future. His primary offensive technique is a massive sphere of black energy that is spawned from his hands that home in on their targets. He can also use the energy spheres to move himself and others through time. Since Mephiles absorbed Shadow's shadow, he also has the ability to actually be his shadow, as seen in the first boss fight against him. Furthermore, he can alter his physical form to sink into the ground and merge with the shadow of another. He can also manipulate shadows to create "clones" of himself, although they are warped and imperfect without the power of the Chaos Emeralds. He can also merge the clones together to make large shadow monsters. With two Emeralds, he can create an army of perfect clones. As seen in the "Showdown with Mephiles" cutscene, Mephiles can also blast opponents away by firing shockwaves of energy at them. Mephiles' final attack used before fusing with Iblis to become Solaris was a beam of energy (dubbed the "Dark Chaos Lance" by fans) that he extends from his right hand to kill Sonic.

Mephiles appears to be immortal, surviving every fight he takes part in, and whenever he is beaten he seems to just shift into his base form. Whether or not he is capable of feeling pain is unknown; although he reacts to taking damage during his boss battles with Shadow, he merely stood and allowed himself to be shot multiple times when confronting Omega at Wave Ocean. Indeed, when defeated by Shadow a second time, he also declared himself to be immortal, and invincible.

Since he is the mind and will of Solaris, Mephiles also happens to be very intelligent. This is shown in his ability as a master manipulator, being able to easily trick Silver and Blaze into nearly getting his desired result. He is also shown to have adept knowledge on using modern technology, as evidence by knowing exactly which files in Dr. Eggman's computer to use when trying to persuade Silver to assassinate Sonic. This is most likely due to his apparently endless lifespan and time travel power allowing him to study the world around him for as long as he needs to.

Mephiles has also demonstrated the curious ability to, with one Chaos Emerald in his possession, warp the other six Emeralds to his location instantly, which he did after the Flames of Disaster were released from Elise and before reuniting with Iblis. Presumably, he utilized the Chaos Emeralds' magnetic properties to pull this off.

Mephiles also was capable of creating and commanding various monsters, as evidenced by the various monsters that appeared.

Possessing several godlike traits, it took the combined might of three transformed super hedgehogs to defeat him, and even then, they could not actually destroy him. As another testament to his enormous strength, Solaris is one of the few beings seen that has been able to injure someone in a super transformation through sheer force.

Iblis
Being the raw strength and power of Solars, Iblis is a very powerful being. He is able to use pyrokinesis, manipulating fire and lava based attacks at his will. He is also capable of summoning meteors and, like Mephiles, can create his own army of monsters.

Iblis also possesses a large degree of super strength and durability. He is able to life and smash large buildings and is able to resist Silver's telekinetic attacks. Like Mephiles, he is capable of shapeshifting his appearance and possesses the power of immortality, as he always able to come back stronger than before.

Temporal Powers
As a transcendent lifeform, Solaris exists in the past, present and future simultaneously, making him omnipresent throughout time and virtually impossible to defeat, unless he is attacked simultaneously in all time periods.

As a god of time, Solaris possesses the ability to freely manipulate and change the fabric of time itself. According to Dr. Eggman, Solaris is capable of devouring time and space on an incomprehensible scale, encompassing entire dimensions and timelines. He can also create rifts within the time-space continuum which come in two variants: black orbs that can suck objects into oblivion as if they were black holes, and red orbs that can hurl meteors of condensed matter with such force that they can bypass the invulnerability granted by a Super State.

Physical Abilities
Solaris possesses unbelievable high physical durability, nearing that of invulnerability, being unaffected by standard attacks from even super transformed characters. Even when unprotected, Solaris's natural durability is so high that so far only super-charged Chaos Powers from super transformed characters can harm him, hinting an immeasurably high level of durability.

Solaris is capable of energy projection, being able to fire energy blasts so great that they can bypass the invulnerability granted by a Super State. When projecting energy, Solaris can fire it in the shape of both large laser beams and purple orbs that will follow the opponent until it hits. In his second form, Solaris demonstrated the ability to generate an almost impenetrable shield of light that can block any attack and which can only be bypassed when Solaris himself attacks as he has to put it down to launch his own attacks.

Much like his two halves, Iblis and Mephiles, Solaris' physical body appears to be immortal and indestructible, as he easily came back, fully revitalized, after his first defeat by Super Sonic, Super Shadow and Super Silver. His only weak point is his red core that is his consciousness, which is still vulnerable to attacks. By destroying it, it would still leave Solaris' body intact, but he would be unable to use it.

Solaris is also capable of at least limited shapeshifting, allowing him to assume new and stronger physical forms, as seen when he changed the sun-like appendage on his back into wings and became even more powerful.

According to Princess Elise and Dr. Eggman, Solaris also possesses pyrokinetic abilities, which is further enforced by his relationship to Iblis, a semi-sentient fire spirit.

Iblis Biters/Stalkers
Iblis Biters and Stalkers (also known as Mephiles Biters) are lizard-like canines that have succumbed to the control of Mephiles and Iblis. They behave very similarly to each other in that they leap forward with claws outstretched and whip their tails to attack. However, Stalkers are capable of blasting lasers from their mouths, unlike Iblis Biters, which breathe flames. A Stalker can be defeated in two hits.

Golems/Titans
Golems and Titans (also known as Mephiles Golems) are giants with thick armor. Their attack patterns are very similar to each other, however, the Titans are very tough and resistant, having the dubious honor of being the strongest non-boss monster in the game, and can only be damaged with Homing Attacks or thrown objects. Titans must be damaged eight times to be defeated.

Iblis Takers/Mephiles Takers
Takers are airborne, skeletal bat-like creatures. Iblis Takers shoot fireballs, while Mephiles Takers shoot black spheres of energy. Mephiles Takers also swoop at their foes when in close quarters. A Mephiles Taker can be killed in two hits. They are useful for crossing large gaps by using Homing Attacks on them.

Iblis Worms/Mephiles Worms
Worms are enormous purple leeches controlled by Mephiles and Iblis, They rise from floors, walls or ceilings when the enemy is nearby and attack by sweeping their bodies around. Mephiles Worms exhale toxic gas for an extra attack. They take six hits to be defeated.

Mephiles
When Solaris was separated into two beings, Mephiles started off as a pile of dark goo. Later on in present time, he takes on the form of Shadow, nearly replicating his appearance, with the exception of the lack of a mouth, and has green pupils. Everything red on Shadow has also changed into a shady blue. Eventually, his third and final form takes on more of a crystallized appearance of Shadow, lacking a mouth, nose and feet. He also gains red eyes mixed with his green pupils.

Iblis
Iblis initially started off as a rock that shattered into a ball of flames. As time went on, Iblis evolved into a monster composed of lava and rocks. His first form had four arms and was armored up with rocks. His second form took on more of a serpent appearance, gaining sharp horns. His final form takes on more of a humanoid appearance where he gains two arms, two legs, and a tail. Like Mephiles, he lacks feet.

In all of his forms, Iblis always has green eyes. In his second and third form, he gains a third eye on top of his forehead.

Solaris
"Who knew such a tiny flame could bring such devastation?"

- Princess Elise the Third about Solaris (aka the Flame of Hope).

Prior to the Solaris Project, Solaris was nothing more than a tiny, pearly white, flicking flame. After his two halves, Mephiles and Iblis, fused together, Solaris took on a more creature-like form, a hawk-like, skeletal apparition, recognizable from the Soleanna royal crest worshiped as sacred by the citizens of Soleanna for countless years. During the battle against him, Solaris' main body is revealed to be a rather simple figure: He has a large and transparent body made of pure light, with a red orb that is his consciousness/core in the center of his body. He has no head, his upper body only includes the top piece above his core, with a curve behind his "neck", and his lower body resembles a. He has three fingers on each claw-like hand with no visible palms, and his arms are not connected to his body at his shoulders.

In Solaris' first form, he is an incandescent, vaguely half-humanoid figure, with rocky cladding on its arms. He has three shells of light covering his body, giving him a more complex appearance. He has one shell covering each of his upper arms, and one main shell on his body. The lower part of the main shell covers his "chest" area, as well as his core, and the top part of it has a figure, resembling an eagle head with glowing yellow eyes and antlers. This makes it look like Solaris actually has a head. On his back is a ring with six triangular pieces "attached", making it resemble a sun.

In his second form, Solaris is a seemingly-skeletal hawk-like spirit. While in this form, he loses his light shells, exposing his main body. On his back, he now has a long plate, with a set of wings "attached", where each wing is made up of five segments.

Trivia

 * Mephiles makes an appearance in The Frollo Show as one of Frollo's friends.
 * Dan Green, Mephiles's voice actor in the English version of Sonic the Hedgehog (2006) also voices Mewtwo from the English dub of Pokémon: Mewtwo's Return, and Knuckles the Echidna who is a former Sonic the Hedgehog villain turned complete and extremely popular Sonic the Hedgehog hero. However his most iconic role is Yami Yugi from the English dub of Yu-Gi-Oh!.
 * Mephiles' name is derived from Mephistopheles, the demon from the legend of the German magician Faust, and possibly after, the personification of the poisonous gases emitted from the ground in swamps and volcanic vapors.
 * Mephiles may also be inspired by the "False Prophet" within the Book of Revelations of the Bible as he works in the shadows and manipulates the characters into doing things that would only further his own goals.
 * Silver's theme song, "Dreams of an Absolution", calls him a preacher who lies which could also be a reference to this.
 * Another possible origin for Mephiles' name may be from Arabic, similar to Iblis. Mephiles could refer to "Muffles" (مفلس), in Arabic Muffles means "broke", "a person with nothing". The term extends not just to material objects, but to everything non-material as well, such as good deeds, emotions, hopes, dreams. In a religious context, Mephiles/Muffles/مفلس is a name for the devil (similar to Iblis) and it refers to him as having no good deeds, no hope for redemption, and no chance of salvation. Taken this in mind, and Mephiles' nature in the game, they would seem similar.
 * Mephiles is one of the evilest villains in the Sonic franchise alongside Erazor Djinn, Black Doom and Infinite. While most Sonic villains have a sense of morality, Mephiles has none. He will do anything to anyone in order to complete his goals, and he will do it sadistically.
 * Iblis's name came from the Iblis, a Djinn from Islamic lore who refused to bow down to humanity only to end up as the one who corrupts the humans out of revenge.
 * The 6 stones on Solaris's back turn clockwise with Sonic and Shadow being controlled however with Silver, his stones turn counter clockwise (after several hits).
 * Solaris, at least in its second form, looks remarkably like part of the crest of Hyrule from the Legend of Zelda series.
 * Also in his second phase, he vaguely resembles the legendary fire bird known as the phoenix, which symbolizes rebirth and immortality.
 * In his first phase, Solaris has six stones on his back, 6 claws on his hands, and six horn segments on his head. This may be a reference to the number 666, which is generally the accepted "Number of the Beast" from the Christian Bible's Book of Revelation. The angelic second form of Solaris can also be looked upon as the true form of Satan (originally known as Lucifer and publicly known as The Devil), the most beautiful angel but also the most evil being in the universe.
 * Despite this, it is actually the Evil One who resembles Satan, not Solaris.
 * Solaris' own core is closely resembled by that of the Time Eater from Sonic Generations. Further similarities between the two bosses include their shared power of time travel, and the fact that they can destroy the timeline with relative ease.
 * In further reference to the Book of Revelation, Solaris' two halves, Mephiles and Iblis, represent the False Prophet and the Beast respectively. Both creatures' names are also derived from synonyms for The Devil.
 * The Time Eater has a similar ability: to alter (and destroy) time and many of powers that Solaris has.
 * Solaris is one the few final bosses to be canonically battled by more than one super transformed character, or by one super transformed character and a character transformed in a similar way; the other ones who have that trait are the Finalhazard, the Time Eater, the Egg Salamander, and the Egg Wizard.
 * Out of all of these bosses, however, Solaris is the only one that required more than two super transformed characters to defeat, with a total of three.
 * In the second phase of Solaris, the music is an instrumental remix of "His World".
 * Solaris was first hinted to have existed within the Sonic the Hedgehog comic book universe when Ian Flynn confirmed that the events of Sonic the Hedgehog (2006) had occurred in the comics on the Ask Ian discussion board. It was first later in Sonic the Hedgehog: The Complete Sonic Comic Encyclopedia that Solaris was officially revealed to have existed, along with details about its history.
 * The Archie Comics was originally going to have Solaris be in the main story of the Sonic the Hedgehog comic series. However, the character was scrapped, and only an artwork picture is left of the idea.
 * Mephiles made a cameo in the Zone Jail in the "Scourge: Lockdown" arc of Sonic Universe, meaning that part of Solaris may have survived. Though it is also probable that this is but an alternate Mephiles.
 * No one knows where Solaris came from. Some believed him to be one of the Seven Ixis Master Works, a set of mysterious creations rumored to be crafted by Mammoth Mogul and the Order of Ixis, while others believe it always existed.
 * According to writer Ian Flynn, he believes the Time Eater, one of the antagonists of Sonic Generations, is actually what is left of Mephiles, who managed to slip through a crack in time. While this applies for the comics, it is unknown if it is true for the games, but Ian Flynn states that it is implied for the games, considering the hints and similarities of the Time Eater's appearance and its abilities. However, this might just be a coincidence.
