* OneSceneWonder: [[spoiler: The final episode has Jason Navery come out of retirement to play Skull one final time, with it being shown Skull has become rich in the meantime.]]

* Fanon: Given the final episode has [[spoiler: Skull shows up in a limousine to pick up Spike most fans assume Skull has become very rich in the time since we last saw him. The most commonly cited theory as the source of his wealth is that Skull refined his piano skills from ''Series/PowerRangersZeo'' and became a professional pianist.]]

* HarsherInHindsight:
** Ricardo Medina Jr's role as sword wielding villain, Deker, became this after Medina ended up having an altercation with his roommate, ending with said roommate being killed with a sword and Medina pleading guilty to voluntary manslaughter.

* CompleteMonster: [[TheChessmaster Serrator]], the Nighlok King, outclasses even Master Xandred in terms of evil. A [[BadBoss horrible boss]], Serrator [[EstablishingCharacterMoment introduces himself]] slaughtering an army of Master Xandred's Moogers and will callously throw away the lives of any of his minions if it suits him. Taking pleasure in tormenting the Rangers, Serrator attempts to force a group of Islanders to [[InvoluntaryBattleToTheDeath fight to the death]] to perfect his new gun weapons. Serrator later [[TheStarscream betrays Xandred]], and attempts to kill Xandred's CoDragons Octoroo and Dayu. Serrator reveals to Dayu and Dekker that he is responsible for turning then into accursed Nighloks for all of eternity, taking pleasure in their suffering. Serrator also uses far viler minions than Xandred to attempt mass death and destruction on the populace in order to create cracks in the Earth at specific points, which Serrator plans to use to split the Earth so the Netherworld floods it, in an attempt to take over both worlds. Callous to the potential deaths of billions of human and Nighlok alike due to his plan, and sadistic to horrific degrees, Serrator is one of the nastiest foes to ever face the Rangers.
