Here's the place for vendetta move list brainstorming
Vendetta is based on Vega. He's gotta have wall dives and good pokes. Maybe some backhand scourge stuff.
There are a lot of really solid normals in the game, like Das boot, Geiger gun, lum punches, etc. I feel like his pokes have to do a lot just to even compete and stand out.
B: tumbling strike, aka Vega's roll
C: wall dive, can also grab in air if you press again
Air B: frost web. Maybe another stun thing like DeGrey Ghost and theoretical Gwen
Air C: maybe a back flip backwards or something?
Super: something fast, I dunno
Air super: maybe poison?
