Mario Kugutsu

Personality
Mario appeared to be a very timid and easily spooked individual. When Kunckleduster approached him while yelling, he was very easily intimidated by the Vigilante. He also was very apologetic, apologizing when he dropped his suitcase and revealed the toys inside.

However, this was revealed to be an act to get away from the Vigilantes and Heroes. He was revealed to be a person who prays on people who have either a weak will or fragile pride and offer them the drug Trigger in order to make them go berserk with their Quirks. He displayed a sinister side to his personality, showing some kind of perverse obsession with toys and the drug itself.

When under the affects of the drug, Mario regressed into a childlike state, contradicting his Quirks appearance. He began to play cars, and anyone who he was able to grab hold of, like they were toy airplanes, even making the sound effects as he did so. He appeared to mentally regress back to being a child completely.

Quirk and Abilities
Mario Kugutsu's Quirk: Mario's Quirk was only seen under the effects of the drug Trigger - However, when it was seen, it turned his body completely black, grew him to a colossal size, and gave him four arms.
