Capsule J2 is an enemy and a Helper in the Kirby series, debuting in Kirby Super Star Ultra. It is best known for replacing Capsule J from Kirby Super Star. Like the earlier Capsule J, Capsule J2 provides the Jet ability and is a carbon clone of the original in terms of attacks and behavior.
With the exception of its head and facial area, Capsule J2 also physically resembles the original Capsule J. Rather than looking like a robotic Waddle Doo like Capsule J, J2 looks more like an actual plane. It has an eerie, shark-like head and a pair of high-powered rocket boosters. It has a lower jaw-like extension and glowing red eyes.
