Bane
Strenths:
-Good range on normals & specials
-Good fwd & back dash
-Capable AA with uppercut and ring toss specials (air grab)
-Fair amount of mix up combos for the short list of them he has.
-Great corner game
-Awesome Trait IMO ( but is also his achilles heal covered below & in link) Venom has 3 levels, basically 110,125,150% damage boost
-Trait also grants specials armor. lvl 3 is projectile imune and also armors F2 & F2D normals. Allows above par preasuring & can allow you to stuff a huge number of wake ups.
-Great punisher, with Venom it's possible to blow someone up for 50%+ off standard BnB's very easily, no venom is also good.
-Little need for plain MB specials. Good to finish combo's with them for extra damage, Bat Breaker! no need for them to start combos or keep them going except for bounce cancels if you wish.
Weaknesses:
-No projectile or ranged attacks at all. Closest he has is Raging charge across the screen, which can be read easily.
-Can range from very to exceptionally difficult at times to "get in" on an opponent even with Venom due to the above.
-Slower attack speed compared to much of the cast
-Venom cooldown. The more of it you use lvl 1,2, or 3 the longer the cooldown time ( see link below). During this time you have reduced speed and take extra damage depending on how much you used; Lvl 3 can make or break your match...
Playstyle:
Generally rush in their face type, Get in & stay in or at least close. Don't want to get full screen against most of the cast if you can help it. wake up stuff & corner lockdown lovin type guy.

I feel this was a bit long for what the OP was asking but his Venom is pretty integral to his game.
