I think in most cases one personality would become dominate in the fused person. Though I can's speak for the Aries/Tifa fusion as I have no idea which Aries you mean. I expect in the StarFire/Raven fusion that since we're usieng thier animated versions (the animated versions have diffrent personalites than the comic ones, comic Starfire is more of a Space Amazon) that Starfire would dominate "Ravenfire"'s personality makeing her extermly upbeat. I'm also going with "Classic" Daphne and Velma, with Daphne dominateing, makeing her smart but shallow (the new Mysteries Inc incarnations give Daphne more depth Velma a much stronger personality)
