I want to say Arrow, provided they start a reasonable distance away from each other. His aim is probabaly better than Beast's dodging ability. One arrow is all it'd take to slow him a bit...then he's done.
If it gets to close quarters, Ollie's no slouch at hand-to-hand, but he's probably screwed.
...and who made your new sig Kahn? It's not perfect, but Spidey sigs are always cool. 🙂
