This Badnik is deployed in Newtrogic High Zone's Botanic Base. The nasty-looking spike on its head isn't only used for defence; Spiketower 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 player.
Spiketower is the only enemy in the game that is completely invincible.
