The latter's easy: Wolverine. Aside from being my favorite character of all time, dude pushed Raiden to his absolute limits... and cut off his arm. Not too many Death Battle combatants who lost can brag about taking off one of their limbs.

The former's tough. It's a toss-up between Spider-Man, Batman (he did win against Cap), and Iron Man. All three are awesome.
