Imagine if the dreamworld friends started to rebel against Omori after finding out what Sunny has done and blamed it on him,or finding out Omori has been pushing Sunny to end himself. They would try to rebel,and defeat Omori. Obviously Omori would lose due to disadvantage,but would come back with the message ''Omori will not succumb''. He would then prooced to restart everyone/make them forget what happened.
The fact that this version of Perfect heart has a attack that Inflicts *Stressed out* is kinda cool. Although idk what Stressed out does outside of the Normal story.
