Bristleback's Pretender shell is a monstrous, turtle-like creature. Similarly, his inner robot is a four-legged beast, possibly with wings. He folds up to become one of Monstructor's arms. His simple transformation to beast mode is similar to that of Birdbrain. He comes with his shell, shell plate, a gun, and a fist for Monstructor.
