Minority of One
The old feats here of him fighting with GL and Aquaman made me laugh. GL is so far outside Deathstroke's weight class... It's an instant win for Hal. Pretty much a curb stomp for Arthur too.
The trick is to find his average range. Keep in mind, other characters have feats taking down Deathstroke too, and they directly contradict some of the strength, speed, & durability feats shown above. So the question is - whose feats are valid, because they all can't be.
