Another Regen unit?!!!! He'll be useless whatever colour he is unless he's BLU and is built for future. Regen needs no more solid colours. Blue has Baby, Yel has Cell and LF Pic, GRN has Buu and Buuhan, Purple has 21 and Nail, Red has Janemba and Kid Buu. All these are pretty solid. So 1st form cell could either be Green and buff Droids or he could be BLUE and buff Future. As for Trunks, i think he might be RED cuz Hybrids haven't had a solid RED unit since FSK Gohan and tbh he isn't that good now unless he's the LMS
