- Hun recalls that he "did okay" with Ch'Rell, even though he was an alien.
- Dramatic Irony: Though Stockman insists Not Me This Time, viewers know he actually did have a minor role in all of this. Like the Turtles and Bishop, he had been manipulated by the Foot Mystics in Season 4, being the the one who activated the laser that destroyed the Heart of Tengu.

- No Challenge Equals No Satisfaction: Discussed by the Tengu Shredder after he fends off some attackers."Ah, I am pleased. I had worried that assuming control of this world would be boring. Now, destroying you all will give me enough of a thrill to keep me amused for centuries!"
- Not Me This Time: Stockman can only say one definitive thing of the demonic activity: that he had nothing to do with it.
- Oh, Crap!: Hun when the seemingly defeated Tengu Shredder grabs him.
- O.O.C. Is Serious Business: Bishop gets rather unnerved as the demons attack his base."What are these beasts?! What's happening to this city?! [points a gun at Stockman] I require answers, Dr. Stockman."
- Pay Evil unto Evil: As Joi says, the human Acolytes are going to return the favor for what the Mystics did to them the last time they fought. When it's all over, Mikey admits that was most satisfying.

- "The Reason You Suck" Speech: As the assembled heroes are outside the throne room and discuss how to get inside.Tengu Shredder: [laughs] It won't be necessary to break through. Come right in. I've been waiting. I see before me children and freaks who carry the trappings and weapons of the Dragons. Could you be the students of the Ninja Tribunal? You are pathetic! You have no power! You cannot stop me!
