Non Disney Villains Tournament
Prior to the events of the war, Shou Tucker performed a series of vile scientific experiments upon Mok Swagger, ultimately turning him into the psychopathic monster that he is. Shou remains out of the line of fire for most of the war, only for Mok to hunt him down. Though shocked at first, Tucker manages to combat his foe successfully using ideas. He likens Mok, now notorious for performing his own perverse experiments upon animals and others, to himself, claiming that the two are working towards a better scientific future. Amused by Tucker's words, Mok decides to let him live, if only to be tortured.
