Bzzit first appeared unnamed in the original Rayman game, where he is encountered in Anguish Lagoon. He is the first mini-boss, and once he is defeated by Rayman, he collapses and starts sobbing. Rayman stops his victory dance to comfort him, and they soon become friends fast, Bzzit helping him cross the rest of the lagoon by offering a ride on his back. In the Atari Jaguar version of the game, he can shoot balls of energy with his proboscis.
As a boss, Bzzit is always airborne, but has less than half of the health points Moskito has, making him much weaker. He attacks by swooping horizontally at Rayman, sometimes at his head level (where Rayman can hit him head on) or near the ground (he can hit him by throwing his telescopic fist and then ducking immediately), and by stinging him with his proboscis. He will also tries to dodge Rayman's attacks using his small wings, and every time he is hit, he flies high in the air and out of view for a brief moment before attacking.
In the original version of Rayman 2, mosquitoes, members of Bzzit's species, make brief appearances in the Woods of Light. In the Sega Dreamcast version of Rayman 2, these mosquitoes also appear in many other levels throughout the game. In Rayman Revolution, Bzzit himself makes a reappearance. He was first mentioned by a baby Globox in the Minisaurus Plain, who tells Rayman that the Pirates have captured his friend Bzzit; later, the Teensies at the Teensie Circle in the Minisaurus Plain told Rayman that Bzzit was being held prisoner in a forcefield (akin to the one Ly was held prisoner in at the Fairy Glade) in the Bayou. He was the only one who could ferry someone from the Pier to the Lost Island (the location of the Sanctuary of Water and Ice in this version), so when Rayman saved him, Bzzit gladly offered him to hop into his boat and took him to the island in search of the first of Polokus's masks.
In this game, Bzzit has four insect-like legs instead of the floating hands and feet which he had in the previous game. He is also noticeably smaller than before.
