History[edit | edit source]

Demolition John used to be a traveling circus strongman whose parade number was to lift a 2,400 lbs bull over his head, However, his income was lousy.

One day the circus got a rare blue tiger. John had previously heard that a corrupt museum director was prepared to pay 2 million yen for such a tiger, so later that night he snuck to the tiger's cage, bent the steel bars and snapped the tiger's head. He got busted shortly afterward and went berserk around the circus until he was stopped by two A-Class heroes.
