You'll usually see the cranky Crain Brain on the defensive, using his great strength to provide some much-needed muscle for the Renegades. And he is mostly muscle—although Crain Brain considers himself something of a genius, he's unaware that most other Renegades have started calling the dim-witted GoBot "Lame Brain" behind his back. When the need arises, Crain Brain's heavy-duty crane arm lets him haul and lift fortifications into place... or casually deconstruct enemy defenses in his path.

Renegade Rhetoric[edit]

Crain Brain was onboard the Renegades' Thruster when Doctor Braxis turned their own guns against them to steal a Sonic Amplifier. Shock and Awe

Crain Brain and Scorp intercepted a recently-arrived deep-space mission as they re-entered Gobotic space after a long absence. Some members of the crew chose to join the Renegades, including Vain Train. Cy-Kill chose to team up Crain Brain and Vain Train for "obvious reasons." Brother's Keeper

Crain Brain was one of the Renegades on Cy-Kill's basketball team as part of his latest scheme to destroy the Guardians. Though their teamwork was poor, Dr. Go helped them cheat with the help of a telepathic chip that let them control the ball. In the ensuing match, Crain Brain and Crasher blocked Leader-1; he later stole a pass from Treds and dunked the ball from halfway across the court to tie the score. Double Dribble

Crain Brain accompanied the newly-sentient Rube to Earth on a mission to steal Doctor Blanco's Transmutation Ring. Crain Brain continually mocked Rube's inexperience and penchant for rookie mistakes. This backfired on the Renegade after an exasperated Rube found a kindred spirit in the similarly belittled Blanco. The two abandoned Crain Brain, who contacted Cy-Kill with news of this latest development. One Born Every Minute

"Brain Problem Situation"[edit]

When the Renegades tricked the Guardians into leaving Earth and then shielded the planet beneath an Embargo Field, Crain Brain and Doctor Go watched over the field's projector in the Eiffel Tower. They were ultimately defeated by Tri-Trak, Nick Burns, and the dimension-hopping Spy Changers Wheeljack and Trailbreaker. Ask Vector Prime, 2015/09/30 TFWikiFavicon.png

"Echoes and Fragments"[edit]

Echoes and Fragments Deadlift Fracture.jpg

In a hybrid universe where the Transformers and GoBots coexisted, Crain Brain, Spoons, and Screw Head used their vehicle modes to breach the walls of Autobot City, singing as they went. Crain Brain was sent tumbling into the river when Hot Rod and Kup used the Renegades as impromptu ramps. On the way back to Cybertron, Zero pushed Megatron and several other dying combatants out of Astrotrain. They found Unicron, and after Megatron bargained for his life he and his troops became new servants of Unicron. Crain Brain was reformatted into a mindless Sweep, loyal to Deadlift.

  • Crain Brain (GoBot, 1983)
    • Enemy Robot Crane
    • ID number: 24
    • Accessories: Jib
Released as part of the first assortment of smaller carded GoBots, Crain Brain transforms into a Unic K-200B crain crane. His crane jib is a separate piece that needs to be removed for robot mode, otherwise it ends up in a very in-a-pro-pro position. Unfortunately, there isn't anywhere else to put the jib in robot mode, so it just sits to the side.
He is a straight import of the Machine Robo Crane Robo toy.


  • Despite two very fleeting appearances in the cartoon, Crain Brain received two entirely different character models, one for each appearance. His debut in "Flight to Earth" is heavily toy-based, while "Cy-Kill's Escape" refined his character model to give him more humanoid proportions.
  • His 1983 profile claims that he can lift a "zillion pounds." Zounds.
  • Crain Brain's Cybertronian-style body in the "Cataclysm universe" and in "Echoes and Fragments" is modeled on Combiner Wars Hook.
