Their origin is unknown. According to legend, they were made to bring destruction to the entire galaxy. The Birdmen destroyed many cities of different planets, overtime. They enjoy destruction but they also have a goal. That goal is to find Ioni (humanoid phoenix woman), worship her and carry out her will. They found Hollow Earth sometime after Argost's defeat and wanted to destroy it for fun. Thrash sensed their presence and confronted them. He simply overpowered them with his own will and forced them into doing his bidding. Thrash and Lilith made a deal with these Birdmen. If they can make everyone on Hollow Earth submit to them by any means necesary they will revive Ioni in return.
