10 Comic Characters Who Have Beaten The Batman
8. Deathstroke
Like many Batman villains, Deathstroke: The Terminator functions as a dark mirror to the, uh, Dark Knight - an already tough-as-nails assassin with enhanced strength and healing powers thanks to a Captain America style super soldier program.
Batman and Deathstroke have fought multiple times and, as the hero, you'd expect the Bat to come out on top. This isn't the case in Deathstroke #8-9 though, in which the assassin beats Batman senseless before leaving him prone, defeated and humiliated atop a building ledge.
Bats shouldn't feel too bad though - after all, Deathstroke did take on the Justice League (Batman and Superman notably absent) all by himself in 2004's Identity Crisis. He did pretty well for himself there too.
