Abandoned Warehouse. Nighttime. Adam Jensen with all abilities fully unlocked with a combat Rifle against Batman with all of his toys. To make this fair(er), Batman knows where Adam is, but Adam doesn't know where Batman is.
Jensen easily. Batman gets blitzed:
While it's impressive how he reacted to the bullets after they were already so close, that's hardly something Batman will get "blitzed" by. Hell, it's really not even that much faster than Batman.
Jensen has EMP hardening as one of his upgrades, so that's not gonna work. Also, dodging combat rifle bullets from 1 to 2 feet away is an extremely high end feat, especially since the rounds are caseless fletchettes and travel faster than ordinary bullets.
