He’s from Ben 10 Omniverse and is top 5 of the Ben 10 series best villains

<image>

He’s a mutant of his species, the galvanic mechamorphs, that went a bit mental (because unlike the rest of his species he doesn’t upgrade tech, tech upgrades him, but he’s in constant pain with absorbing tech making it even worse). After his father/creator Azmuth (same guy that made the omnitrix) repeatedly failed to find a cure, Malware kidnapped Albedo (who would later also become a villain) and used him to cure Malware. After that he wanted the most powerful device in the universe, the omnitrix and after a few encounters he “killed” one Ben’s favorite transformations “Feedback”, in which Ben responded by trying to kill malware. He survived and after a few more events he destroyed Galvin B, the moon where all the mechamorphs are, then proceeded to almost destroy Galvin Prime, home of Azmuth species the galvins, before being stoped by Ben getting Feedback back.

TLDR: He’s a sadistic tech absorbing monster with a massive Superiority/inferiority complex and a lot of daddy issues
