Gaibon is a gargoyle-like enemy who appears in Super Castlevania IV, Castlevania: Symphony of the Night, Castlevania: Dawn of Sorrow, Castlevania: Curse of Darkness, and Castlevania: Portrait of Ruin. His skeleton appears in the background in Castlevania: Harmony of Dissonance. Gaibon attacks by flying through the air, intermittently spitting fireballs down at the hero. In Super Castlevania IV, he can also land and knock stalactites down from the ceiling. Upon taking damage, he turns red and begins firing bigger and more powerful blasts of fire, as well as moving in different patterns. His soul in Dawn of Sorrow allows a Gaibon familiar to follow Soma and attack with him, and is used by Soma at the end of Julius Mode. Gaibon is always seen paired with Slogra, perhaps from their initial appearance as two of the final four bosses in Super Castlevania IV.
Gaibon is the first boss battle of the game, and then is a randomly encountered enemy, on the boss battle he teams up with Slogra, he spits fireballs at the enemy while Slogra impales them with his spear, if he gets low on health Gaibon turns red and starts to spit larger fireballs and steps on the ground to shoot even more projectiles at the player, however if the player brakes Slogra's spear first, Gaibon will start to grab Slogra throwing him at the player for massive damage.
