The ostensible leader of the Campbellian's attacks on earthling cities, Garuda oversees the deployment of the Slave Monsters (monster of the week). He is able to change his appearance at will from a blue-skinned, blonde-haired human to a humanoid eagle. After numerous failures to destroy Combattler V and the Nanbara Connection, he is stripped of his rank by Oreana. Soon after, he learns the truth of his origin: That he is actually the last in a line of androids created by Oreana to be her perfect son and the leader of the invasion force. Consumed by revenge, he finishes building the incomplete slave beast Big Garuda and uses it to destroy Oreana.
