Berserker (セキアス, Sekiasu) is fought a total of three times in Legend of Legaia. Its Lv2 and Lv3 forms are later fought within Rogue's Tower, though they are actually Rogues mimicking the structure of the original Berserker. The Berserker is first fought in the Sky Gardens of Jeremi after it turns around to attack the Ra-Seru heroes who had tried to interrupt its process of absorbing energy from the Genesis Tree.
