Spiketower  ( is an enemy that appears in ザック  Zakku ) ? . It is a mass-produced Knuckles' Chaotix Badnik model created by Dr. Robotnik.
The Spiketowers only appear in
Botanic Base. In gameplay, the spikes on their head is not only used for defense; they can fire them straight upwards like grappling hooks, wedging the projectiles in the ceiling and winching themselves upwards on wires, swinging back and forth like pendulums to hit the playable characters. Despite this rather novel adaptation, these Badniks are not all that dangerous as they swing radius is rather limited. They cannot be destroyed.
"Zakku" is Japanese for "thud".
