Magnesium Man took part in the final battle against Chinnos in Vindicators: Crystal War. After Chinnos said that he was going to make the planet into a utopia, Magnesium Man said that while Chinnos said "utopia", he heard "kill everyone". He then told Chinnos that he didn't want to find a new dry cleaner. He then told Chinnos that him making jokes was a distraction so that Airshot could take Chinnos out. After Chinnos had his head blown off by Airshot, Magnesium Man said "aww, what's the matter? Bad head day?" Chinnos then used an app on his phone to restore his head before turning all the Vindicators into crystal using the Doomsday app.
In the real world, Magnesium Man flew to the Simpsons' house and told Bart not to spoil Vindicators: Crystal War 2: Resurgence anymore because the fate of his universe depended on it. He then threw Bart through a portal into their universe, which was actually a virtual reality world created by Marble Studios for Bart. Magnesium Man told Bart that they took him from his dimension to theirs. When Chinnos attacked, Magnesium Man told Bart not to spoil anything as their universe depended on it. Magnesium Man then took part in the fight against Chinnos' army before he helped to defeat Chinnos with the rest of the Vindicators.[1]
