um...
He can transform into Super Saiyan Rosé (similar to SSB)... that's actually probably an evolution (i'mma write that down for a DB card game)
I have his main energy attack as Graviton Cannon. He takes an energy sphere and punches it, creating a ki beam.
Also Seismic Impact, which is the same energy sphere, but thrown and it makes an explosion.
Finally, singularity sphere. He summons the orb, crushing it in his hand, turning it into a black hole type thing he throws at you. It absorbs energy and he can cause it to detonate with that energy, making a massive explosion.
