Zakku is a Badnik deployed in Newtrogic High Zone's Botanic Base that appeared in Knuckles' Chaotix. The nasty-looking spike on its head isn't only used for defense; Zakku can fire it straight upwards like a grappling hook, wedging the projectile in the ceiling and winching itself upwards on a wire, swinging back and forth like a pendulum to hit the Chaotix. Despite this rather novel adaptation, the badnik isn't all that dangerous as its swing radius is rather limited. Simply destroy it on the ground or when winched up by a spin jump.
