Nightwing vs Katana Nu52

Nu52 versions of both. Standard gear.

Dick's latest showing was fighting nearly evenly with Bruce in Nighting #30, although I'm not sure if Bruce was holding back or not.

Katana's showings include being able to causally chop machine gun fire in half

This is an insane showing of pain tolerance, strength and durability for Bruce and Dick.
