Based on what? Zsasz wasn't as big a name as Poison Ivy and Clayface yet he was locked up just the same as far as I know all of Arkham is maximum security
Also he didn't really get in the heads of anyone in the jail he was In at least not anuff to make any real difference.
I don't see Lecter having a problem. As long as he doesn't wear a costume. He could probably get close enough to some of the rogues to kill them. Not in a fair fight but by blending in and being sneaky.
This is true. He is an absolute master at understanding abnormal psychology while his own is inscrutable. If he managed to get some fake credentials, he could easily convince the Arkham staff to place him on staff by wowing them with his insights. He'd offer the Gotham PD consultancy too, get in good with Gordon and the rest. It's the perfect roll for him in a crossover event.
Hannibal could even get close to Bats, help him with cases, like he does with Will Graham—although on the other end, Hannibal might have been the one who manipulated the criminal in the first place.
This would make for a great crossover movie or miniseries event. Add it to the ones we'll never see—a long, long list as we all know.
he would find kindship with bruce, after figuring out who he is. for those who dont know, lecter was of Lithuanian nobility, up until the nazi bombed his home, killing nearly his entire family, save for himself and his younger sister. then later on, he and his sister were captured and she was killed and eaten in front of him. so it would fascinate him to see how someone who suffered a similar tragedy to him handled his own traumas.
Out of all people, I remember it being brought up that Zsasz sneaked in and out of Arkham to carry out murders.
And Lecter was "chummy", or at least had a sense of mutual respect, with one of the guards watching him despite how he broke his arm to get him away from the nurse he maimed. He has too much class for blind vengeance... unless it was about his sister I guess. He carried out a young movie Magneto hunt then.
Key word being (hallucinogens) really not as impressive if drugs are Involved.
Anyway I really don't see what effect pretending to be a character from wonder land is going to do I mean do you think lecter is going to dress up as the queen of harts and order MH to eat he's own face? Even if he did MH doesn't follow the hierarchy of the book he is in control
