Spawnmower was one of Ivo Robotnik's many specially designed Super-powered 'Bots intended to destroy Sonic. After two failures, Spawnmower was sent as the third robot to be pitted against Sonic, and arguably the most formidable. He could have devastated the entire Great Forest if not stopped, but fortunately had the flaw of stopping periodically to strike a pose. Sonic was thus able to pull his spark plug wire, allowing him to push Spawnmower off a nearby cliff.
- Spawnmower is based on the fictional comic book antihero Spawn.
