Question: Except for Two-Face, Killer Croc, Scarecrow and Jervis Tetch, why were the rest of the villains redesigned?
Question: How could Batman be infected if he cured himself of the Joker's poisoned blood in Arkham City?
Answer: He was exposed to a toxin bomb, so he probably got a bigger dose of the fear toxin.
The fear toxin only makes a person see their worst fear. It doesn't make them physically transform into it.
Answer: He was exposed to the fear toxin when it was unleashed on Gotham City.
How does that explain him being still being infected? The four people he had at Panessa studios were infected by a blood transfusion but Batman cured himself of his. Plus, the fear toxin only makes a person see their worst fear.
Answer: He was infected through a blood transfusion.
The Joker infected Batman with a blood infusion in Arkham City but Batman cured himself so, it would make no sense for him to still be infected.
Question: Just where did the militia get the money for all their weapons and gear? The only rogue who's got good money is The Penguin, and he doesn't seem capable of necessarily funding a whole army.
Answer: All the villains financed the Arkham Knight: Penguin, Two Face, Harley, Scarecrow. This is why Two-Face and Penguin stayed in Gotham and risked getting gassed to rob banks and run guns; they'd dangerously low on funds.
Answer: The Arkham Knight is behind the whole thing. He probably financed it somehow. Given who he turns out to be, probably from stolen drug money.
Answer: Probably because different people were working on the game. Scarecrow and Croc also have different looks if you've played Asylum, City, and Origins, they look different here too.
