- Hope Spot:
- The first time Karai hits the Tengu Shredder with her anti-magic weapons, he's reduced him to pleading for mercy before she stabs him in the gut. He soon reveals he was just toying with her.
- Chaplain blasts a hole in the Tengu Shredder's torso to keep him from striking down Karai. The Tengu Shredder responds by laughing, healing himself, and getting back to business.

- No, You: Karai's not very good at trash-talking. She does this several times to the Tengu Shredder.
- Oh, Crap!: Karai when faced with the giant serpent.
- Sadist: The Tengu Shredder feigns pleading for mercy and pulls a Shapeshifter Guilt Trip to make turning the tables on Karai more amusing for himself.
- Shapeshifter Guilt Trip: While not exactly a shapeshifter, the Demon Shredder fulfills the spirit of the trope when he uses his human face, the same as Karai's adoptive father's one, to take her off guard at the very moment when she seemed to have an advantage, though he later states that he was just playing with her the whole time.
