He appears as the boss of level 3: River of Destruction. in here, both of its arms each have individual attacks. The Left Beast Arm periodically spits fireballs at the player, while the Right Beast Arm periodically spits a short, homing flame burst. Once both arms are destroyed, the alien’s head begins attacking. It periodically spits a large ring of projectiles that break into 2 smaller ones; these smaller ones fly towards the player. The weakness of this boss is its Pulsing Core, which becomes vulnerable after the 2 arms are destroyed.
