Jervis Tetch (aka the Mad Hatter) is a delusional Arkham Asylum patient obsessed with Lewis Carroll’s Alice in Wonderland. Using mind control tech by way of his big fancy hats, Mad Hatter’s addition to the film would no doubt be accompanied by potentially beautiful dystopian wonderland visuals and totally awesome quotes to repeat at the office over and over and over again. We’re talking like the level of that last really popular Dane Cook album.
5. Hugo Strange
Professor Hugo Strange is a brilliant yet insane scientist and psychologist driven by pure obsession to fight the Dark Knight. Strange was the first villain to discover Batman’s secret identity and uses this to his advantage, striking at him emotionally. The physical approach is left to the genetically engineered monster men he created as his own private army. The manipulative dialogue alone would make him a great addition, and super-mutant monster people are always an added bonus.
