A second-generation Badnik. The Octus resembles an octopus but is designed to function on land and in the air rather than in water. It has a large spherical head and a pipe-shaped mouth, which fires laser blasts. Its body is a fat disc with 6 limbs attached that rotates as the Octus flies.
Octus Badniks first appeared in Sonic the Poster Mag 5's story, Ocean of Horror! They have made very few appearances in Sonic the Comic, but in Issue 131's Shady Characters Part One, two modified Octus Badniks are seen with extendable tentacles to grab Amy and Tekno.
