Yeah, Bleak Black is the only truly villainous one as he’s controlling the other members through their second personalities which he planted into them in the first place.

Just a thought, Rainbow of Revenge could be the debut of Commander Merge. Maybe Fusion-X uses him to train Susan Violet into becoming powerful and skillful enough to defeat Bleak Black and the Hue Crew and save her parents as yeah, she should be the one to save the day but I think Fusion-X should still play a role, such as through Commander Mode. Also maybe Fusion-X could be the one to free the Hue Crew after they’ve been defeated? I wonder if there’s a Merge Mode that can remove their second personalities, Psychic Merge maybe?
