A minor UK-based legacy supervillain from my current Mutants and Masterminds game. Doctor Domino is obsessed with causality, planning his schemes and his deathtraps like complex 'Rube Goldberg' machines.
Nice. Actually he was a throwaway creation. One of the PCs couldn't make it, so the GM said, "He was called away by the government to stop a fiendish plot to topple Stonehenge by... um... Doctor Domino." Everything came from there.
I like yours, though. Damn nice clean linework. I'm a sucker for it.
