Baron Draxum's History
Baron Draxum is a mutated warrior and alchemist from a Hidden City beneath the streets of New York City, who desires to bring humanity under his control by mutation. Approximately thirteen years before the events of the series, he came across a Battle Nexus champion named Lou Jitsu and decided to mutate an army of animals using the human's DNA. This led to the creation of the Turtles, but Lou Jitsu destroyed the laboratory and all of Draxum's work.
Thirteen years later, Draxum was able to produce more of the mutagenic ooze and now intended to mutate humans using his Oozesquitoes. However, his plans were interrupted by the Ninja Turtles and their friend April O'Neil, who fought Draxum and his minions and destroyed his laboratory.
Despite the destruction of his laboratory, Draxum survived and later clashed with Big Mama and the Turtles over the Oozesquitoes in Bug Busters. Having been thwarted again and angered by his creations' continuing defiance, he created The Evil League of Mutants (consisting of Meat Sweats, Hypno-Potamus, Repo Mantis, Warren Stone, and the Sando Brothers). During a battle with the Turtles, Draxum revealed his past association with Lou Jitsu, but was drawn through a portal and found himself with the Foot Clan.
Having a common enemy in the Turtles, Draxum formed an alliance with the Foot Clan, agreeing to complete the Kuroi Yōroi. Draxum believed that he would be given the armor when it was complete. This brought him into conflict with the Turtles once again, and also with Splinter, who revealed himself to be Lou Jitsu. He eventually became frustrated with his lack of progress in the Foot Clan, and after engineering a triumph for himself, he took control of it.
Draxum reappeared after capturing the turtles and April when they arrive at the first car of the train, stating that he will never have to look at them again. He then fought Splinter, demanding him to release his sons, which Draxum refuses unless Slinter gives him the final piece of the Dark Armour. This had forced Splinter to do so by using Leo�??s sword and grab the piece from the portal he created. Just as the turtles arrive, Draxum added the last piece to the armour, donning with the it so that he can be unstoppable.
However, he was defeated when April hit a baseball into the Jupiter Jim action figure, which was stuck at the back of the helmet, causing him to lose the armour and his life force.
Following losing the armor, Draxum was left on the streets alone, destitute, and almost completely depowered. Michelangelo found him and set him up with the apartment above April's, trying to get Draxum to become a good person. Raphael and April found out about his residence and objected to it, but after a dinner with them, Donatello, Leonardo, Splinter, and watching Draxum perform his first act of selflessness in saving some humans, they began to accept him. Still feeling he needed to channel his anger in a creative outlet, he was given a job at April's high school as a cafeteria cook.
While the Turtles and April watch a game with the New York Daves (who have been transformed into demons), Donnie calls Draxum to inform the group about the Arch of Aquinnah and how to reverse its effects.
By the series finale, Draxum and Splinter had come to treat each other as allies and accept each other as the Turtles' two fathers after the battle against the Shredder.
