5) Matt Murdock/Daredevil
The origins story:
By day, he’s a hotshot lawyer, cleaning up the streets of Hell’s Kitchen the legit way. But by night, Matt Murdock is the cunning, super-agile Daredevil, taking down NYC’s goons on his own dime despite the fact that he’s legally blind, having lost his vision in a childhood accident that heightened his other senses to near-superhuman level.
What would really happen:
That stuff about one’s other senses becoming heightened as a result of suddenly losing sight? Yeah, that’s actually true. In the case of Matt Murdock, that would probably amount to a slightly better sense of taste and smell and more acute hearing, but the ability to become a martial arts master and expert prowler, minus any sense of spacial awareness? Forget about it. Murdock could be a great lawyer, but if he carries on playing Daredevil he’s just going to hurt himself. Not even people with 20/20 vision get that lucky at fighting.
