"No one controls GRIMLOCK!"
— Grimlock to Shockwave

Grimlock is a Cybertronian Autobot and the leader of the Dinobots.

Personality Edit

Grimlock is huge and powerful and is stronger than most other autobots (if not all). Though with such power comes an ego, he constantly refers to himself as "king" and refuses to take orders unless their under his terms. Grimlock is wilful and will not give up even if the odds are against him. Despite his power his intelligence is very limited due to the experiments which were conducted on him, so he can be easily tricked by simple word play that or he will crush the person for not understanding. Along with this he also has a very short temper and will go into violent bursts of rage when he is in battle. 


Early HistoryEdit

Grimlock's robot mode.

See The Dinobots for more infomation on early history

Grimlock was the leader of the Lightning Strike Coalition Force, a commando unit in the Autobot army. While investigating an unusual energy emission from the Sea of Rust Grimlock and his team were captured by Shockwave (a Decepticon scientist) and his creations known as the insecticons. Once captured the team were experimented on, their alt-modes being turned into creatures from the planet Shockwave was researching and their intelligence levels decreased. However during a pain-based test Grimlock managed to escape his restraints, freed his allies and put a stop to Shockwaves plans. The team then made their way to the arc but missed it, though they managed to hitch a ride on the Protoform ship and eventually landed on Earth.


Once landing on Earth the LSC were found by Razorbeast, who renamed them the Dinobots and managed to convinced them to join his mission to find the other Protoforms. After awhile Grimlock got fed up of taking orders from Razorbeasts and decided to leave, the rest of the dinobots joining him. It is unknown where they went, however recent footage from tourists in Africa suggest that they may be spending their time in an old junkyard deep within the country.

Weapons and AbilitiesEdit

  • Energo-sword - Grimlock's sword uses energon to power a shaped energy field that significantly enhances the cutting and blunt-impact properties of the weapon. When the fuel cell is consumed, the weapon can still be used at its "normal" potency.
  • Transformation - Like all members of his race, Grimlock is able to transform into a tyrannosaur. In this mode Grimlock is able breathe fire and run faster.
