Characters you'd want to see in a future DBZ game?

They can be characters that have never appeared before, or hypothetical characters that could exist (within reason).

I'd want Super Saiyan Turles and Super Buu w/Vegito? Any other ideas?

Thor.

why would a Stargate character be in a DBZ game? 😬

King Cold with 5 forms

Frieza with 5th form(with this new movie it might not be needed)
