Batman from Arkham series vs Ip Man from the movie of the same name.
Round 1 : H2H on the same place Ip Man fought General Miura. Weapons, batsuit or other gears are not allowed. Both combatants are using regular Karate or Judo gi's.
Round 2 : Melee combat. Bruce has his Batsuit and Ip Man has a Dao sabre.
His version of Chen Zhen from "Legend of the Fist: The Return of Chen Zhen"
He outran mounted machine gun bullets, was launching guys with hits, and had a bunch of other superhuman feats. He'd give Arkham Batman a good fight and his skill plus his stats would give him some wins.
Another is Dragon from Dragon Tiger Gate. They were all just blatantly superhuman in that one with a lot of wire-fu and chi attacks and stuff.
Just did some research, Legend of the Fist looks above Nolan Batman but well below Arkham Batman, him outrunning machine gun bullets was just him outrunning the line of sight according to this video
