In Dragon Ball Super's latest preview for episode 123 and the new ending(Lagrima) it depicts the prince of all saiyans in Super saiyan blue but with the hair more sleeker,sharper and darker, like more of a royal blue. What could this be? I believe it is either a bit of ultra instinct and super saiyan blue combined, Super Saiyan Blue 2, or mastered super saiyan blue. What do you think?
