These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ace Combat Equestria Chronicles
Ace Combat: The Equestrian War
Chaotic Neutral: Gilda. Type IV: she doesn't fight for anyone or anything, but herself.
Complete Monster: With the revelation that Red Cyclone is planning genocide of all ponies, he certainly qualifies. He won't even hesitate to sacrifice his own troops if it means killing his foes.
Gilda during her first appearance, given the gleefully sadistic way in which she thrashes Rainbow Dash and breaks Medley's wings.
Moral Event Horizon: General Silverbeak appeared to have crossed it by suggesting a plan to kidnap little fillies and using them as hostages in the early phase of the war. It is revealed in chapter 14 that it was actually Red Cyclone's idea.
Gilda's betrayal and her brutal beating of Rainbow Dash in chapter 11.
The Woobie: Every main heroine at some point, but especially Derpy.
