The Book of Spider-Man (Ultimate)

[Lord Pyre]

I'll pitch this power again:

POWER AND RESPONSIBILITY
When a figure you control within 4 clear sight spaces of Spider-Man receives one or more wounds from an enemy figure's attack, once during your next player turn, you may add 2 to his Attack number while attacking that figure.

Gives him a bit of a "reluctant" feel, but lets him hit really hard when he needs to. Still works fine with the protection power, and lets him be either a protector or avenger as needed. Paired with Otto or Pavitr, you can swap an OM to him or take a turn with him if your next turn will work really well with his attack boost.
