Morro tries to escape the grasp of the Preeminent, but fails, and is about to be sucked in. Wu flies over to save him, but Morro refuses. He finally accepts that he is not the Green Ninja, and turns good, but only for a few seconds, before he is sucked in to the water.

This would be higher if Morro didn't return in DotD, because that just ruined this moment to me.
