Dark Danny

"Your time is up Danny. It's been up for 10 years."

- Dark Danny to Danny Phantom

Dark Danny, also known as Dan Phantom, was the evil older version of Danny Phantom and the main antagonist of Danny Phantom: The Ultimate Enemy. He was created as a result of the ghost forms of Danny Phantom and Vlad Plasmius fusing together. He is the most evil and one of the most powerful Danny Phantom villains.

He was voiced by Eric Roberts who also played The Master in the Doctor Who movie, Sal Maroni in The Dark Knight, and James Munroe in The Expendables.

Creation
After Danny Fenton used his powers to cheat on the Career Aptitude Test in an alternate timeline, Mr. Lancer who'd been suspicious of him, asked his family to come to the Nasty Burger for a meeting. Sam and Tucker were also there, but the Nasty Burger's vat of condiments exploded, killing everyone except Danny. Left orphaned by the tragedy, Danny was forced to move in with Vlad Masters, since no one else could understand his situation and despite the hatred that the two had shared for each other prior, Vlad treated Danny with great sympathy. However Danny couldn't deal with the guilt anymore and asked his former archenemy to remove his ghost half, believing that it was responsible for the deaths of his family and friends. He also thought that his ghost half would be free of all emotion, ridding him of the pain and guilt that he was feeling.

Vlad agreed to help and tore Danny Phantom out of Danny Fenton with the Ghost Gauntlets, but after the procedure, Danny Phantom did the same to Vlad and bonded with his ghost half, resulting in the two selves fusing together. As such, Vlad's evil overwhelmed and destroyed all the goodness of Danny's original ghost self and as such, Dark Danny was born. Now, no longer possessing any empathy or remorse, Dark Danny responded by brutally killing his former human self before blowing up Vlad's mansion. With that mission complete, Dark Danny then flew off to unleash a ten year period of destruction throughout the Human and Ghost Worlds.

Facing Danny Phantom
When the Observants saw the terrible future that Dark Danny had unleashed, they commanded Clockwork to destroy Danny in the past so as to prevent Dark Danny from ever coming into being. However the time ghost instead sent in various future ghosts that set off a series of events that caused Danny to end up in the future to confront Dark Danny, who'd been reducing the future Amity Park to rubble, having finally gotten through its ghost shield with his Ghostly Wail power. Danny was no match for his evil older self and eventually Dark Danny fused him with a time medallion that trapped him in the future so that the half-ghost wouldn't be able to stop him from coming into being.

Realizing that Clockwork was trying to stop Danny from turning into him, he threw his past self into the Ghost Zone to make sure he stayed out of the way and then transformed himself into a fourteen year old version of his human self. Dark Danny used another time medallion to go to the past to ensure the events that created him would happen, however Danny's sister, Jazz, found out what he really was. He successfully cheated on the C.A.T. using the answers (which Danny had obtained earlier by accident), causing Lancer to call his parents over to the Nasty Burger as a demonstration of what awaited those who failed the test. Sam and Tucker came to try and warn them of the imminent explosion and Jazz arrived, proceeding to use the Fenton Ghost Peeler to reveal Dark Danny. He managed to used ectoplasm to trap them on the condiment vat,which was coming close to exploding, but then Danny Phantom arrived, having succeeded in getting the time medallion out of him with help from the future version of Vlad.

Dark Danny could never kill his younger self, but only had to hold him off until the sauce exploded and even with the Specter Deflector and Ghost Gauntlets, Danny couldn't defeat his evil older self. However his determination to save his family and friends caused Danny to unleash the Ghostly Wail power, which he had used earlier while under attack by future versions of ghosts he had fought. This shocked Dark Danny, since he was not supposed to gain that power for 10 years and Danny told him that the future apparently was never as predetermined as he'd thought. He unleashed a second Ghostly Wail that blasted Dark Danny into a building, who emerged extremely battered and weakened and was trapped in the Fenton Thermos. However Danny was too weak to save his family and friends in time, but Clockwork's intervention saved them and he sent the half-ghost back to before the test so as to give him a chance to change his future. The time ghost then took charge of Dark Danny, who existed outside of the timestream now that Danny would never become him. However he was seen smashing against the sides of thermos, apparently attempting to escape.

Personality
Dark Danny is pure evil and while other Danny Phantom villains had some level of morality, he has nothing of the sort. He is cruel, sadistic, destructive, and utterly heartless and perfectly fine with killing anyone, even if they were once people he cared about, in order to fulfill his own goals. Dark Danny is also highly arrogant and egocentric, most likely because there was no one in the future able to fight him, and this made him underestimate his younger self.

Powers and Abilities
Dark Danny has the combined powers of Danny Phantom and Vlad Plasmius at his command, making him extremely powerful. Similar to his good counterpart, he can sense nearby ghosts and half-ghosts with red wisps of mist emerging from his nose when one is nearby. Dark Danny's ghost powers grant him superhuman strength, speed, agility, and durability and he can fly and turn invisible and intangible. His most powerful attack is his Ghostly Wail, a powerful shriek of sonic force that sounds like moaning ghosts and can use it more than once without losing energy, unlike Danny who can only use it one or two times before feeling a severe energy drain. Dark Danny has a wide variety of powers and can possess other people, fire ectoplasmic energy blasts, unleash a pseudo-electrical attack to shock people, generate an ectoplasmic energy shield, create duplicates of himself, form bonds made of ectoplasm, teleport, shape-shift into a version of his younger self, create portals to the Ghost Zone, manipulate the shape of his body, use a sleep beam to knock people out, turn into ghostly vapor, and fuse objects into beings with his intangibility powers, making it unreachable by human or ghost means.
