Mystic Brothers (ミスティックブラザー, Misutikku Burazā): The Mystic Brothers are a duo consisting of the ostrich-like Mystic Runner (ミスティックランナー, Misutikku Rannā) and the Egg Headder (エッグヘッダー, Eggu Heddā). To attack, the Mystic Runner kicks the Egg Headder at enemies like a soccer ball and can also fire energy bolts from its beak.
Mystic Gosei Great
After combining with the Mystic Brothers, Gosei Great becomes Mystic Gosei Great (ミスティックゴセイグレート, Misutikku Gosei Gurēto). The Mystic Runner attaches to Gosei Great's left shoulder and the two halves of the Egg Headder attach to its feet, forming a shoulder-mounted flail. For its finishing attack the Mystic Strike (ミスティックストライク, Misutikku Sutoraiku), the Egg Headder encapsulates the opponent and when the egg opens again the monster is trapped in a buble that promptly destroys it. First seen in Epic 13.
Mystic Datas Hyper
Mystic Datas Hyper (ミスティックデータスハイパー, Misutikku Dētasu Haipā) is the combination of Datas Hyper and the Mystic Brothers. The two halves of the Egg Headder cover Datas Hyper's hands and allow it to shoot out blasts of energy, while the Mystic Runner attaches to the top of Datas Hyper, enabling him to fly like a helicopter.
