Orga Sabnak is the drug enhanced Pilot of the GAT-X131 Calamity. He appears to be the leader of the the first stage extended's used durring the Battle of Jachin Due. He enjoys reading paperback novels.
Orga and his two teammates, Cloth Buer and Shani Andras are First-stage extended, they make their first appearance durring the Orb battle, they are given their dosage of the drug "Gamma Gilpheptin" which performs their battle capabilities, they also have had several biological modifications to condition their minds, eliminating fear and adding an aggressive to them in combat.
What Orga and his other two teammates were unaware of however were the side-effects of the drug. After a duration without the drug, it would have the negative effect of causing intense pain and harm their nervous systems without a regular dose of it, this was a trick to keep the trio from turning traitorous, by promising regular doses of the drug in exchange for loyalty to the Earth Alliance. If the three failed orders they would go the night without the drug and face the massive pain.
Orga is the apparent leader of the trio, piloting the GAT-131 Calamity and is the most stable of the three. Even though he is in this position, he shows little care for friendly fire, nearly hitting both Shani, and Clotho of several occasions.
Even though he is the most stable, he still gets pleasure out of destroying enemy mobile suits or rather he gets pleasure out of battling his enemies, and dislikes to leave the fight unfinished, this is shown when Captain Natarle Badgiruel orders him to retrieve the pod holding Flay Allster, he is shocked and a little bit angered that he has to perform this tedious task.
Orga is shown to enjoy reading novels as most of the time he is seen reading and nothing more.
Orga is also shown to care about his team, this can be seen when Shani is killed, Orga immediately yells his name.
Orga Sabnak is killed shortly after Shani by Athrun Zala and his ZGMF-X09A Justice with the "METEOR" weapon system.
