i feel like they got played. trigon always wanted to possess Raven, and they just made the work easier for him. in the first place, how was trigon even chained ?
I hope that Raven doesn't betray him during or after the fight because she became evil or something because of all the absorbed powers. If she is I hope that he can save her by beating her just like a DBZ character.
-Shallot needs to learn Magic!! DbSuper's magic is pretty OP even, Moro devouring energy from some Planets hit Goku and Vegeta Blue and managed to fight Goku MUI, Raven devouring the Half Brothers and territories didn't even reach the level of Super Saiyan Lol
