Kirby Mass Attack sprite
|“||The tougher Skullions guard the Necro Nebula. Skullys grow into Skullions over a hundred years. They must be fierce!”|
|— Daroach • Kirby Mass Attack|
Skullion are the mature forms of Skullys, and appear in Kirby Mass Attack. They have a similar appearance as Skullys, but Skullions have a tiny horn on their heads. It takes 100 years for the Skullys to reach this stage, according to Daroach.
In Kirby Mass Attack
Skullions are only encountered in the fight against Necrodeus, where they try to repair his broken wrists. Necrodeus will also send some Skullions to attack during the last few phases of the battle. Skullions will try to snatch up the Kirbys in the same way as Skullys. However, they are faster and stronger than Skullys, but their health is still low, so they are easy to defeat.
Skullions also guard Necro Nebula before it's conquered.
