This Hot Wheels x Transformers Bone Shaker converting action figure brings together the rat-rod attitude of the classic Hot Wheels car with the shape-shifting fun of Transformers. It transforms between a detailed robot mode and the iconic Bone Shaker car in 22 steps, featuring a menacing skull grille and flame decals in vehicle form. The robot stands 5 inches tall and comes with a shifter accessory that doubles as a mace and can be attached in either mode. This is part of a larger Hot Wheels and Transformers collaborative series—other figures are sold separately.
