140px-Sonic3&K Badnik Toxomister

Toxomister is an immobile, cylindrical Badnik created by Dr. Eggman. They can be encountered in Sonic & Knuckles's Lava Reef Zone and they constantly surround themselves with poisonous gas that will drain the player's rings if they are caught in a gas cloud. The gas can be shaken off by spin-dashing or by destroying the Toxomister, which can only be struck in its eye.
