Multiple Man + The Atom + Nitro

I choose Blink.

stark already figured out that "current" nitro's powers are sound based, he prematurely triggered his explosive power by emitting a sound that was analogous to the one that makes nitro blow up. so i say stark does it again, before nitro/maddrox/atom can make dupes or shrink.

Invisible woman?

Leech with a machine gun.

Bump

I choose reed Richards with prep. I design a device that not only tracks your guy, but depowers him also.
