This is the place for BBB move list brainstorming
Since Arg has more or less been confirmed by Sirlin telling everyone to shut up about staff versus stretchy arms (RIP team Staff) I guess BBB will have to be more like sentinel than Dhalsim.
I guess his normals will be slow robo punches, maybe his neutral can do 2 punches. His jump punch DEFINITELY needs to be like sentinel (it's even in his art!)
B: Gyro spin, a lariat that knocks back and far, like Jaina's uppercut, but maybe not invincible.
C: extensor grab, a ranged command grab to mixup on block, but isn't armored.
Air B: junk shot maybe? Maybe it's like Geigear but... Something I dunno.
Super: either piston or graviton, but whatever it is, it will probably knock back far
