Mother Russia vs. Daredevil

Matt as of Season 2

Fight takes place in the Octagon

*Matt has his morals off

Matt beats her ass

If a trained, yet pubescent, girl on adrenaline can take her out, a guy who steamrolls through small armies of ninjas definitely can. Especially if Matt's morals are off.

She's physically stronger, but I'd give it to DD via a rear naked choke
