There's Ironcladman, of course - am I allowed to mention Marvel? Someone said the Hulk, so I figure it's OK... Mr Hyde-type minis might be a good Hulk substitute, the whole 'scientist goes crazy and becomes a behomoth' thing is pretty much directly ripped from Jeckyll and Hyde.
What would the Victorian equivalent of Batman be? Two suggestions come to mind:
1 - a wealthy industrialist playboy (read, wealthy aristocrat with a penchant for gadgetry) takes to solving crime by night? Top hat, cane, cape, and a mask like for a masked ball would do the job I think...
2 - reclusive rich man takes to hunting evildoers by night, disguised as a giant bat... hunting... at night... disguised as a bat... hunting at night as a bat... capes come into this one too, but in a much more sinister way: Victorian Batman is a Vampire who (tormented by his carnal lusts) only feeds on evildoers through a perverted sense of justice (and because he sees it as the only possibility of salvation).
Just some suggestions for you there - feel free to use or ignore as you see fit!
