Skullseer

Skullseer is an enemy in Spectrobes. He is the leader of the Skully that were created by Necrodeus, and as such, is a member of the Skull Gang. Skullseer appears in Stage 5 of Magma Wastelands, where he can only be fought if the Team Billy use the key they obtained earlier to unlock the door near the end of the level. Skullseer resembles a giant Skully with large horns, glowing red eyes, and fangs.

Phase 1 & 2
In the first phase of the battle, Skullseer will send out some Skullys to attack the Team Billy. The Team Billy have to defeat them all. This prompts Skullseer to descend downward and fly around. The Team Billy then must attack by climbing on top of him, in the same manner that they attacked the Skullys.

Phase 3
In the final phase of the battle, Skullseer will join the Skullys and try to snatch up a Billy Hatcher. If he is not rescued in time, Skullseer will abduct him, at which point the Flain can't be rescued. After he's defeated, Skullseer will disintegrate and give up a medal.

Etymology
Its name comes from the words "skull" and "seer."
