Goku Black

"I'm from a much higher place than you and I've seen the truth of this world, this universe and all the things in it. I noticed the results and decided that Human beings should be destroyed. Humans are the one and only failed creation of the Gods. In order to make the world, the universe a beautiful paradise, I want to annihilate the humans on Gods' behalf, who won't admit their failure."

- Goku Black revealing his plans for humanity to Future Trunks.

"What's wrong, Mortals? Has the work of a God left you frozen in fear?"

- Goku Black during his final battle Goku Black (mainly just referred to as Black) is one of the two main antagonists of the "Future" Trunks saga of Dragon Ball Super alongside Future Zamasu. He is a mysterious evil being who bares a striking resemblance to Goku and has caused the Earth's second apocalypse in Future Trunks' timeline. Eventually though, it is revealed that he is actually Zamasu with Goku's body. He is one of the biggest threats in the entire Dragon Ball franchise as he poses a threat to all time and space. Black is the mastermind behind the Zero Mortal Plan and specifically recruited the Future Timeline version of Zamasu to assist him.

He was voiced by Masako Nozawa.

History
Zamasu was originally North Kai of Universe 10, but due to his incredible and unique fighting abilities, he was selected to undergo training to become the next Supreme Kai; becoming the pupil of the current Supreme Kai of Universe 10, Gowasu. However, as Zamasu started observing multiple planets, he began to distrust and grow a hatred of mortals, believing that they've abused their god-given wisdom and continue their mistakes of enacting war and violence upon their worlds. Some time later, Gowasu and Zamasu are visited by Beerus, Whis and Goku; the latter of whom challenges him to a sparring match. Upon Gowasu's approval, Zamasu fights with Goku, but is overwhelmed and defeated when he transforms into his Super Saiyan 2 state. Angered that a mortal possesses power capable of challenging the gods, Zamasu grows an obsession towards Goku which only increases his hatred for mortals.

Some time later, Zamasu learns about the Super Dragon Balls and, upon hearing about their power to grant wishes, decides to take matters into his own hands. Zamasu then kills Gowasu and takes his Potara earrings, inheriting his position as Supreme Kai. He then manages to gather the Super Dragon Balls and wishes to switch bodies with Goku, becoming Goku Black. Upon switching bodies, Black immediately traveled to Earth and killed Goku along with Chi-Chi and Goten.

Using the Time Ring, Goku Black traveled to Future Trunks' timeline, where a God of Destruction no longer existed in his universe, killed Future Gowasu and aligned with his future counterpart. Once again, the duo gathered the Super Dragon Balls and wished for Future Zamasu to become immortal; destroying the Super Dragon Balls after the wish was granted. Together, both Goku Black and Future Zamasu killed all the Supreme Kais in Trunks' timeline, eliminating the Gods of Destruction due to their life-link and removing possible opposition from the Gods. With no one left to stop them, the two enacted their goal to wipe out all the mortals, dubbing it the 'Zero Mortals Plan'.

Goku Black traveled to many planets, destroying life on every one of them, calling himself Goku and proclaiming to be eliminating the mortals in the name of justice. Black eventually arrives on Future Earth and quickly brought humanity to the brink of extinction until Future Trunks tried to stop him. Future Trunks spends over a year trying to fight Black, with Trunks constantly being defeated and barely escaping with his life. Soon, Trunks went into hiding waiting for Future Bulma to prepare the fuel to use the time machine to go back to the present for help. Upon sensing Trunks' ki, Black destroys Bulma's lab and kills Bulma in front of Trunks. He also appears to kill Future Mai after she tries to stall him. Enraged, Trunks attempts to fight Black, but Black beats Trunks very easily and charges a ki blast sphere. However, Trunks then throws his sword and blasts Black with a Masenko. Black blocks his attack then he loses sights of Trunks until Trunks came out of the ground in the time machine. He then tries to blast Trunks with a Dark Version of the Kamehameha, but Trunks successfully manages to escape and travel back to the present timeline in the time machine.

Following Trunks' departure into the past, Black continuously tries to sense for Trunks across the planet until the Time Ring has a strange reaction and creates a portal leading to the past timeline. Entering the timeline, he finds Future Trunks as well as Goku and Vegeta. Enraged, Trunks attempts to go and challenge Black, but is stopped by Vegeta while Goku confronts Black in his place. Black attacks Goku with the same Golden-Black ki blast sphere he tried to kill Future Trunks with and sends Goku flying. Goku then powers up to Super Saiyan 2 and fights back, with the two seeming to be evenly matched.

However, throughout the fight, the Time Ring attempts to pull Black back into the future timeline. Black fights it until he could no longer resist the Time Ring's pull and is eventually forced back into the future; but not before destroying Trunks' time machine. Upon returning, he collapses from his injuries after his fight with Goku, but is not upset and says he will get stronger from said injuries and regains his composure. Black proceeded to test his increased power, using a Golden-Black ki sphere, bigger than it's usual size firing it, pleased with his increased power and embedding Goku's fighting style into his own.

With his new power increase, Black attacks the base of the Resistance, formed by Future Mai and the surviving human's who struggle to defend Earth. Black easily dominates and kills half of the Resistance and causes the rest to retreat and form a new base.

After Future Trunks, Goku, and Vegeta travel to the Future, Black confronts them and then fights Vegeta in his SSB form. Black moves closer catching Vegeta off guard. Vegeta then attacks Black with a barrage of punches but Black blocks all of them. Goku Black then transforms into his own God Form called '''Super Saiyan Rosé. ''' He then resumes the fight with Vegeta but stabs Vegeta badly with an Energy hand sword. Goku then joins the fight while Future Trunks takes care of Vegeta's wound. The two fight evenly until Future Zamasu appears and stands besides Goku Black.

The two then fight Goku overwhelming him until Future Trunks helps Goku fight them. Goku fought Black and Future Trunks fought Future Zamasu. Black backed Goku into a corner and Future Trunks's attacks didn't have any effect on Future Zamasu. It's then that Future Zamasu reveals that he has gained immortality and can not die now. He then grabs Goku and Trunks allowing Black's Kamehameha to hit them. The two take damage and just when Black and Future Zamasu were about to finish the Saiyans off, the injured Vegeta stops them. Soon the Resistance rescues the three Saiyans and they retreat to the past. Future Zamasu then says to Black that they will be back.

Later, when Goku and his friends return to the future, Black and Future Zamasu go to confront them. When Goku calls Black a "fake", Black tells him he is incorrect and reveals his true identity to Goku. He is actually Zamasu from the present timeline, who switched bodies with Goku and killed him, hence why his ki is similar to Zamasu's. He then tells them that while Beerus did indeed destroy his past self, the Time Ring prevents changes to the timeline from affecting him. Goku, Vegeta and Trunks then power up and prepare to fight Black. As they fought with Black and Future Zamasu, having the upper on the Saiyan trio, Black and Future Zamasu reveal that after Black stole Goku's body and killed him, he murdered Chi-Chi and Goten as well in cold-blood. This caused Goku's power to rise incredibly due to his anger, Goku then began overwhelming Black but was ultimately defeated nonetheless. As Goku laid down in defeat, Black and Future Zamasu revealed the reasons behind their plans, saying Future Trunks was the one to blame for traveling back and forth through time causing history to change. They called Future Trunks a "Sinner". because of this Trunks awakens a new Super Saiyan form then claiming he would be the one to kill Goku Black and Future Zamasu. Goku, Vegeta and Bulma then retreat while Future Trunks holds off Black and Future Zamasu.

Goku and his friends later return, with Goku having learned the Mafuba technique to trap Future Zamasu. In order to ensure that the battlefield will be their grave, Goku Black destroys their time machine. Seeing that Vegeta is using his anger to become stronger, Goku Black decides to try this as well. As a result of his anger at the mortals who disrespect the Gods and the Gods who turn their heads away to such disrespect, Black is able to summon his energy blade and transform it into a scythe, which he uses to cut a hole in the sky and summon countless copies of himself distracts Goku and Vegeta.

However, after sensing Future Zamasu's ki appear and disappear, Goku Black leaves to see what's going on. Future Zamasu explains to Black that the humans are much more dangerous than they originally thought, prompting Goku Black to fuse with him, creating Fusion Zamasu. However, Fusion Zamasu's body later began to mutate and become unstable due to Goku Black's mortal body combining with Future Zamasu's immortal one; allowing Fusion Zamasu to be defeated by Future Trunks. Future Zen-Oh later erased Fusion Zamasu from existence along with Future Trunks' entire timeline, thus putting an end to both Goku Black and Future Zamasu.

Personality
"Are you done? A pitiful end for the proud warrior race."

- Goku Black's distaste for Saiyans.

He is extremely ruthless, conniving, diabolical, and manipulative, so he has killed many humans including Future Bulma without a second thought saying it was in the name of "Justice". During his fight with Future Trunks, he was enjoying the battle and demonstrates a sense of brutality as he savagely kicks Trunks right arm breaking his bones and then shoots a barrage of Ki blasts at him. Also judging from his derogatory comments about Trunks's Saiyan heritage, it is possible he has some negative feelings towards those with Saiyan blood. Yet at the same time refers to them as a proud warrior race, and finds Trunks's unbecoming tactics for a Saiyan disgusting. He also has high respects for Goku saying it is a honor to fight him. He also shares a few traits with Goku, namely his desire to fight strong opponents and love for fighting, even going as far as not using his full power at the beginning of the battle to have a good fight. Black shares Goku's determination, after seeing Future Trunks disappear in the Time Machine, he promises to find him while claiming that there is nowhere for him to run. Goku Black utterly detests humanity, perceiving them as a blasphemy and God's greatest mistake. He elaborates this by stating that he has scoured several universes and has implied to have seen enough timelines via Time Ring to feel vindicated in his belief that humanity is an existence that prevents the universe as a whole from becoming a true paradise and has taken upon himself to destroy all traces of mankind, who he believes have only been allowed to live as long as they have because the God's are too prideful to acknowledge their failure in creating humans. He shows masochistic traits, such as taking a full-force punch from Future Trunks while laughing, and seemingly enjoys the pain inflicted to him by Goku. However, he is slightly irritated and argumentative, when Trunks threw his sword at him, in order to intercept Black's charged ki blast.

Appearance
"He wears black clothing, so we call him "Goku Black""

- Future Trunks telling Goku about Goku Black.

His physical appearance is identical to that of Goku's but with some differences. He has a more thinner physique and facial structure. His eyes are more sharper and has a somewhat younger look then Goku. His Gi consists of a sleeveless dark grey jacket, a long sleeved black undershirt, a red sash, black pants and white boots. He wears a single earring on his left ear and a silver Time Ring on his right index finger.

Powers and Abilities
"Do you really think you can defeat me with attacks fueled by nothing but emotion?"

- Black to Future Trunks.

He is strong enough to easily beat Future Trunks (in his Super Saiyan form) in battle, gets blasted with a ki-powered shotgun without getting hurt, and kill almost every human within a year. It is said by Future Trunks that Goku Black possesses power equal or greater than Super Saiyan 3 Goku. However, during the encounter with Goku, Black was roughly comparable to Super Saiyan 2 Goku and kept gradually increasing his power during the fight. After his encounter with Goku, Black embedded Goku's fighting style into his own, making him more powerful than before. With his powered increase in his base form he can take blows from Super Saiyan Blue Vegeta until he transformed into his Super Saiyan Ros'e form then Vegeta was outclassed by him. Conventional weapons such as guns won't hurt him and the bullets he caught from said guns were severely deformed. Even after being caught in an explosion that brought Sky Scrapers down on him burying him under he shrugged it off without a scratch. It's been speculated that his power is enough to threaten the entire Universe, and will force the involvement of the Gods of Destruction: Beerus and Champa, the Supreme Kais, and even the Omni-King himself.

Super Saiyan Rose
"How is this color? Isn't it beautiful? If I were to name it in your style, it would be...Rosé. Yes...Super Saiyan Rosé."

- Goku Black after transforming.

Goku Black possess his own version of the Super Saiyan Blue form called '''Super Saiyan Rosé. ''' this form the hair color is Pink with pure white highlights. The eyebrows are a whitish-pink color, and the eyes follow suit. The aura resembles a Flame of Darkness, with a reddish-purple inside. The clothing gains a purple hue and the user glows with purple particles. This form evolves Black to the same level as SSB Goku. In this form he is stronger than SSB Vegeta and defeats him easily by stabbing Vegeta with an Energy Blade made from his aura. It also powers up his Black Kamehameha so much that it could kill both SSB Goku and Vegeta with one hit.
