Kirby: Planet Robobot screenshot
Capsule J3 is an upgraded version of Capsule J2. Its appearance resembles the previous model, but its face is now in the lower portion of the nozzle, with yellow eyes. It has a red and gray jet pack, a fin on its head, and black goggles.
Capsule J3 first appears in Stage 1 of Resolution Road. It can fly and charge at Kirby in an attempt to hit him. It is able to fly at him from the background as well. It is also summoned by Star Dream Soul OS Core alongside Pillah and Waddle Doo.
Capsule J3 primarily appears when Kirby is riding Robobot Armor, as scanning it grants the armor the Jet Mode. If Kirby's Robobot Armor attacks the enemy but does not scan or defeat it, Capsule J3 flies off-screen and is replaced with another.
