the only characters that have invisibility have been chipp in gg, twelve in 3s, and arakune in bb. there might be more but thats off the top of my headOh whoops, typeo, yeah I meant invisibility.
Invisibility's been around for a little while. Guilty Gear had it back in the day, and I'm fairly certain it was around before then as well.
