I think my favorite Gundam series was Mobile Suit Gundam Wing. Don't ask me why because all giant robots are cool in the first place. Who am I to play favorites? But it was. Maybe it was during an impressionable time of my life.
The Tallgeese was the only mobile suit capable of matching a Gundam in combat, piloted by Zechs Merquise in the series. So its an extra special mobile suit.
