Heatrock

Heatrock is an Autobot from the Generation 1 continuity family.

Heatrock, the sixth Protectobot. Despite those sweet shoulder drills, they're not Drill Crusher, Drill Max, Drill Lander, nor Land Bison.

Heatrock (ヒートロック Hītorokku) is all about the drills, drills, and drills. They form the torso of Gaia Guardian and the chest of God Guardian.

• Heatrock (Candy toy, 2012)

Heatrock is a snap-together candy toy model kit produced by Kabaya for their G Guardian series, coming in an individual box packed with a stick of (chalky) gum. They transform from a robot into a drill tank. They form the torso of Gaia Guardian and the chest of God Guardian.

Notes

• Kreon Heatrock uses existing Kre-O pieces as part of their build; they use the Ironhide helmet (though it seems to sport a mouth-plate), but the shoulder-drill arms appear to be unique pieces (to make them better match their original counterpart).
