Sparkly pink war crimesExplanation Glimmer, with her pastel color aesthetic, literal glitter magic, and title of "princess", is the most stereotypically girly of the main cast. This is a hillarious contrast to the fact that she's also a Blood Knight who's constantly pushing for more aggressive tactics and who spends season 4 turning into an Unscrupulous Hero who throws her own friends into harms way to win. Her fans make countless jokes about this subject, often exaggerating this trait to make Glimmer actually Ax-Crazy. The war crimes is no exaggeration, as Glimmer has used child soldiers (Frosta specifically), taken hostages, and (debatably) employed the use of torture, all of which qualify as war crimes by the UN definition.
