- "Let's see how long my next opponent lasts. We're the ones who will bring down the firebird."
- ― Edgar Grint
As part of the Usean Allied Forces, he fought in nearly every operation. He had originally planned to retire, but changed his mind at the start of the Usean coup d'état and served one last time with the Usean Rebel Forces.
He then promised his wife that they would both move to a village in the countryside, away from airplanes after the war had ended.
After his death, pilots in his home country started to name themselves after birds.
- Grint somewhat resembles Marcus Snow.
- Edgar Grint is the only squadron leader in Ace Combat: Assault Horizon Legacy who cannot be defeated before taking out his wingmen.
- It is possible that he trained a pilot who would later become Yellow 13, as he states that "Erusea is full of young pilots brimming with potential".
