Heatrock

Heatrock is an Autobot from the Generation 1 continuity family.

Heatrock, the sixth Protectobot, turns into shorts, or a jumper. Poor fellow.

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

Heatrock was with Skyfeather when they tried to stop Swindle from stealing Metroplex's transformation cog. Bad at Fighting? Rescue Team Protectobots, Dispatch!

Prime Wars Trilogy marketing material

With a growing number of combiners serving in the Autobot military, Autobot commanders recognized that the giants came with several drawbacks, chief among them their inability to function if a teammate was incapacitated. The Protectobots thus inducted Skyfeather and Heatrock onto the team, after Rook but before Medix. Customization class Medix bio

Heatrock: for when Nosecone's busy.

• Heatrock (Candy toy, 2012)
  • Accessories: Blaster

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.

They're the only G Guardian figure that requires a degree of partforming, with their vehicle mode drills being detached during the transformation and reattached into the robot shoulders.

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).
