Bombar (mistranslated as Aero Star) is a rare mini-boss that made his debut in Kirby & the Amazing Mirror. Being a plane, Bombar stays midair during the fight; in fact, he, Batafire, and Master Hand are the only mini bosses in the series (not counting Kracko Jr. and the giant enemies from Kirby 64) that fight entirely in the air. He is also commonly fought in areas with very strong winds, so the Kirby has to be on his guard during the whole fight. He attacks by swooping down at Kirby, shooting guided missiles at him, and even a full-on air raid. The projectiles from the air assault give the Bomb ability, while the guided missiles give, obviously, Missile. Upon his defeat, Bombar himself also grants the missile ability.
Small Shooties can always be found patrolling the area around or outside Bombar's arena and are a giveaway of his presence. They themselves resemble miniature versions of the large mini-boss, but their exact relation is the subject of speculation.
Bombar is a green personified fighter jet wearing antique, old fashioned aviator clothing consisting of a cream colored scarf and an orange flight helmet with a star design on it. His underbelly is a noticeably lighter colored green than the rest of his body and he has brown feet.
