Random location, normal weapons, morals on (basic here, Ollie kills Bruce don't) .
I know Nolan's Batman compared to the comic version is weak, but let's not underestimate him, he was well trained and has alot of toys.
So Oliver has a lot of potential as well, till he has no formal training, he past 5 years trapped in an island and was trained by this probably Russian old guy.
So who would win? Why? How do you imagine the battle?
