Doctor Doom never had powers. Well, he did, but he only acquired them through keen intellect. Giving him powers actually sorta undermines what intellectual boundaries he overcame simply to gain them. A small change that results in a rather huge character difference if you ask me. But I've enjoyed pretty much all the Dooms thus far with McMahon standing as my least favorite.

And the potential thing figures right into my point about Batman not killing. It's illogical for him to leave them alive. The prison and mental health institutions might as well have revolving doors in every cell, the redundancy of continuing to just apprehend his opponents. If would just simply snap a neck, no more lives lost by the hand of the Joker, Scarecrow, take your pick. He's completley capable of it and yet he holds back.

Same with the Flash, would anyone who could move faster than the speed of light honestly ever have any trouble with anybody?

Let's use James Bond, if only someone would've stabbed him or shot him in the head instead of explaining the plan and then using the world's most elaborate death trap.

What I'm saying is I think you're using comic book and cinema's natural fallacy with logic against Shredder as fodder for why you don't like how they've changed him. If you don't like him because they've changed his species, that's fine, but don't lay the logic bomb on him and then hold back on practically every other villain and hero strewn across the fictional landscape.
