Ill Gate resembles a normal door. It has an evil expression on its face, a vicious mouth, and magenta bat wings.
Ill Gate appears exclusively in Stage 7 of Volcano Valley. It does not attack the Kirbys, but when it appears, the area darkens, and Ill Gate switches around with a normal door. The Kirbys must then guess which door is the right one. If they enter the enemy, it takes them to a small room containing one or more enemies; the Kirbys must defeat them to escape. The most common enemies used in an Ill Gate trap are Mossys; semi-commonly, a Big Stactus; and rarest of all, Posuras.
Ill Gate cannot be defeated without Invincible Candy.
Ill can mean evil, and gate refers to the object that it's mimicking.
