Mr. Freeze would not work? Yeah right, if there's one thing Nolan showed especially with Batman Begins, then it's that any Batman villian could work with a little tweaking, no matter how crazy a concept. For example; IGN had an article on how various Bat rogues could realistically work, and they had a pretty good for Freeze. Since I can't find it I'll try to write what I remember. *AHUM AHUM*
Victor was nothing more then one of the scientists working for Wayne's company, working on various cryo-projects, the most important being one that would allow terminal patients to be put into "stasis", granting them more time until a cure would become available. Then one day, his wife is diagnosed with cancer, and she only has 2 more weeks to live. Victor pleads with the board to use his wife as the first test patient, but they refuse, and Victor decides to take a huge risk: He convinces his wife to do it and sneaks her into the tube. The days crawl by as he tries to keep it secret, looking for any possible treatment, but none coming, and in his frustration and growing madness he punishes himself by staying in the cold chamber as long as he can, soon only allowing himself to feel emotion when his body temperature drops. One day he goes too far, and his assistant only barely manages to get him to a hospital, where he stays in a coma for 4 weeks. When he comes by, he hears that he has been fired and that his wife was removed from the stasis tube...And that she had died while he was in the coma. Finally, something snaps in Victor's mind, and he becomes determined to do anything he can to make Wayne's company PAY for effectively killing his wife, using his expertise on cryo-technology to create various ice weapons.
No anti-heat suit, no mutated body, no head-on-robotic-legs...Just a grieving, vengefull madman who wants revenge on the suits who ruined his life.
As for other 'flamboyant' Rogues...Mad Hatter, owner of a tea house that's a drugfront, makes special hallucinating drugs that he always tests on himself, has a sick eye on the 11-year old blonde girl named Alice who lives in the house next to him...Oswald "The Penguin" Cobblepot, owner of the Ice Berg lounge who acts as an information broker to the cops and Batman, but who's secretly the biggest armsdealer in Gotham (using various small contacts to whipe out any suspicions leading to him)...Killer Croc, a thug who grants his nickname because he's so brutal and because he suffers from a rare skin disease/skin cancer that makes his skin look scaley...Manbat, erm....Okay, so maybe you can't turn all rogues into credible movie villians.
