* DemotedToExtra: Cinder, Mercury, and Emerald are swiftly taken out of the story after being subject to a CurbStompBattle by Agnika. Roman Torchwick and Neopolitan are also much less prominent in the story and aren't even mentioned .

[[spoiler:Elevated further when several years after Agnikas' departure; they sent Mikazuki after him in a ship loaded with plenty of spare parts to repair both of their Gundam bodies.]]

* OutsideContextProblem: For Salem and her forces, Agnika counts as one thanks to his presence being a SpannerInTheWorks for their plans. It leads to Salem creating the Andras to counter him.

* RewardedAsATraitorDeserves: Raven kills Lionheart for being a traitorous, self-serving coward after breaking to him the news of Salem's death. She then proceeds to make it look like he hung himself in shame and left an apology note.

* YouHaveOutlivedYourUsefulness: The first thing the Andras does with its newfound power over the Grimm is to order them to kill Watts, Tyrian, and Hazel after [[spoiler:killing Salem]] since they're effectively deadweight now that Salem's out of the picture.
