Planet Terminus is a planet in the Sonic the Comic universe. The rocky, mountainous region is inhabited by giant termites with a taste for wood. Terminus appears to orbit a Sun and is itself orbited by two satellites.
During their travels through the Ring of Eternity, Amy Rose and Tekno the Canary landed on the prison ship Astratraz, where the criminal "Guggets" were rebelling against their captors. Whilst locked in a cell of their own, Tekno began to study a planetary chart and somehow noticed that Terminus was there and who lived on the planet. Seemingly defying her new friends, Tekno volunteered to fly the guggets to Terminus so that they could invade it. However, upon marching out to conquer their new home, every last wooden puppet was eaten by hidden termites. The visiting aliens then contacted base so that they could be rescued.
