First pose I made of the Bear's redesign. He's the originator of Kin's (the protagonist) moving orbs in the game. Kin stole the design from a hacked crawler he inspected, and made into his backpack. (Kin's backpack is called The Breakneck, you'll see soon.)
The Bear acts as a secret boss across all six worlds. If you beat him, you get a secret ending and a secret extra 7th world.
