Garma Zabi is the youngest son of Degwin Sodo Zabi and the youngest brother of Gihren, Kycilia and Dozle. While his siblings were mean, Garma was more handsome. Degwin loved his youngest son as well as the other Zeon forces. At his residence in California, Garma is contacted by his schoolmate Char Aznable that the White Base was sent into Zeon territory and that he would need backup. Garma agreed to help his friend destroy the White Base. After the battle, Garma rests up at his residence and parties while Char prepares something sinister that the young Zeon boy doesn't know about.
At his party with his lover Icelina Eschonbach, Garma is called away to his Gaw fleet. While the White Base hides in a sports dome as Amuro and his Gundam distract the enemy, the Red Comet fools his friend into thinking that the White Base is near the Gundam, when the White Base was behind them! As the White Base, Guncannon and Guntank fire at the fleet, Garma was completely defenseless. Char admits that he had set Garma up for the fall and that his father is to blame. With anger, Garma prepares to ram his Gaw into the White Base but it goes higher into the air. Garma heroically shouted "Glory to the nation of Zeon!!!" before the Gaw goes up with Garma inside. While Icelina went into tears, Degwin showed his own grief by dropping his cane in silence. Gihren gave a funeral speech to inspire the Zeon army.
