Kanzenshuu

Furiza defiantly wouldn’t, unlike Cell and Buu he had the choice to be good or evil, and he chose evil, so I couldn’t ever see him joining the Z Senshi. The only type of villians that would join are the ones who are to weak to make a difference, and to weak to oppose any of the Z Senshi.

I seem to remember in the South Park movie, Cartman had a Ki aura around him at one point that looked very DBZ esq.

The only chance of a new DB anime would be if a series was made as a spin-off from the live movie, but of course the movie has been cancelled for the moment.
