Masher is a second-generation Badnik. A piranha-shaped robot, Masher is a modified version of the Chopper. The changes are minimal, however, as their abilities are the same and the Masher's appearance is only slightly different.
Mashers originate from the Emerald Hill Zone in Sonic the Hedgehog 2. They were moved to the Aquatic Ruin Zone in Sonic the Comic, where one accidentally cut the webbing around Tails' tails, allowing the fox to swim to safety.
