Aside from literally shutting down I think its some 65% of the cast to the point where they can never wake-up after even one knockdown, having one of the best traps in d.1 double punch and b.1 double punch, being meter independent, being able to clash away and get 300% damage output for 6 seconds, having an unblockable quick super that beats out most other supers if you level 3 juice box it, shutting down some of the most major threats like GA, Raven, Killer Frost... Having damage combos equal out to other character super combos using only level 2 venom and one meter, having instant death interactable combos, double punch having a hitbox that can tag the batslide which is the lowest actual attack and clipping people out of the air, his venom uppercut reaching the top of the stage ceiling and taking people like hawkgirl with it, level 3 being both projectile and armor immune on his supers and having full combo damage off of just one or two attacks... His standing 2 nullifying a lot of cross-up attempts because of its crazy reach, having grab resets that peg an extra unscaled command grab for 20% or more onto the end of combos, his level 3 venom super doing anywhere from 54% unscaled to 71% in a combo off of most any good read, his body-splash letting him cross-up people from the air, great reach on his normal attacks, being able to actually wake-up against most opponents which is something a lot of character lack right now...
That's just the tip of the iceberg. He also has some pretty solid meter gain and since he doesn't have as much use for it, he gains the benefit for snagging that staple damage or healing while he burns off the level 3 venom cooldown on the 2nd bar.
