|“||The tougher Skullions guard the Necro Nebula. Skullys grow into Skullions over a hundred years. They must be fierce!”|
|— Daroach • Kirby Mass Attack|
Skullion has largely the same appearance as its juvenile counterpart. However, it has more slanted eyes, larger teeth and a tiny horn on its forehead.
Skullion appears exclusively in and around Necro Nebula. Groups of them patrol the island, grabbing any Kirby that flies there (except one). They create protective coverings for Necrodeus' wrists, and when the Kirbys shatter his wrists, groups of Skullions futilely attempt to repair them. When the battle moves into space, the villain releases more of these enemies to attack.
Like Skully, Skullion flies at a Kirby and attempts to snatch him. It is faster, however, and any Kirby that is caught is immediately lost for the rest of the fight. When the enemy is not on the offensive, an attack from a small group of Kirbys is enough to defeat it.
