Olban is the illegitimate ruler of the Baam Empire and the main antagonist of Tōshō Daimos.
History[]
Olban was formerly King Leon's personal adviser, and had his right-hand man Georiya poison and kill the latter during Leon's council meeting with Earth. Olban then usurped Leon's throne since Prince Richter was too young. He has Richter lead his forces against Earth, but Kazuya Ryūzaki uses the Daimos to fight Baam's forces.
After finding out that Georiya was responsible for his father's death under Olban's orders, Richter is determined to kill Olban. Olban then forces Erika to marry him to legitimatize his rule, and she pretends to agree so she can murder him. Raiza helps Richter to assassinate Olban but fails, and Olban kills her.
Olban eventually plans to turn everyone into zombies to prevent the possibility of a rebellion. Richter confronts and manages to mortally wound him. Before dying however, he reveals a backup plan in case he died to move the Baam Asteroid City towards Jupiter, but Kazuya and Richter manage to prevent this.
