 In the episodes "Mini-Max" and "Countdown to Catastrophe", Obake was revealed to be Granville's student whom she allowed free rein in his research.This resulted in him suffering injuries caused by an explosion from his attempt of creating an energy amplifier, severely affecting his temporoparietal junction which greatly warped his sense of morality and is gradually worsening; despite being given awareness from Baymax, he refuses treatment, finding the condition "liberating".Out of this insanity and his obsessions, Obake masterminded various events in the first season from Globby stealing one of Lenore Shimamoto's paintings for her energy amplifier blueprint to pointlessly learning of Big Hero 6's identities through hacking Krei's personal files and Burger Noodle Boy's prediction algorithm.
