After the streaming, the dev showed all 3 active skills for stage only.

Go+Frieza: A renewal version of original GoFrieza's 18 ki. Good but nothing special.

SSJ2 Gohan: Probably the best version of Father-Son Kamehameha.

Super Gogeta: Soul Punisher with original animation. Also really nice. The KO screen reminds me Dragon ball Fighters SSJ4 Gogeta's one.
