Mosqui
From Sonic Retro
Mosqui (モスキー / Masukii) is notable as being one of the few badniks who has appeared in more than one game. They can be found in both Sonic CD and Knuckles Chaotix.
This little rascal of a badnik attempts to fly down at high speeds and puncture you. They are very easily dodged, and can be destroyed in the air or when it's stuck in the ground.
