Plasma

Plasma is a copy ability first debuting in Kirby Super Star.

Kirby Super Star / Kirby Super Star Ultra
This ability is provided by Plasma Wisp. When gaining this ability, Kirby's color will change to a somehow pale-ish pink color. In the remake, Kirby Super Star Ultra, Kirby's color changes to green rather than the pale-ish pink color. Oddly enough, the artwork of Plasma Kirby depicts him as completely green, but his sprite isn't. This was later fixed in the remake.

Kirby Air Ride
This ability is once again provided by Plasma Wisp. It is only used once in this spin-off game.

Kirby Star Allies
10 years later, Plasma returns, but Kirby doesn't change color at all. This ability is provided by Plugg, Vividria's painting of Kracko, Hyness's pillar of lightning and/or green stars, or Zan Partizanne's green stars.
