This paper toy is the Impossibear, some sort of multi-colored bear who was seen in "Gas-Powered Stick", based on the American animated web series Bravest Warriors, the papercraft created by MrQqn. The Emotion Lord gave him the 'gas-powered stick' which he slammed on Catbug and Plum.
Impossibear is a fat, multi-colored, bear-like creature with an orange-brown mustache on his muzzle. He seems to be somewhat idiotic as he whacked Catbug and Plum with a "gas-powered" stick without any reason. He also seems to be not connected with what goes on and just does what he pleases.
