Grimstone is an Autobot Commander of the Dinobots. He is power-hungry for an Autobot, who longed for the privilege great power brings. Despite this, he knows the purpose of power is to protect the weak, and the responsibility it brings to put others first. It's unclear if undergoing the Power Core Combination process satisfied Grimstone's ambitions and lust for power, but his new Dinobots have certainly made him strong enough to protect the less fortunate.
Profile[]
Not much is known about Grimstone's past but it is believed that he was Kakuryu a member of the Decepticon Dinoforce. He was the dumbest member on the team hopeless, clumsy and kind. It was unknown why he was a Decepticon but it is believed that he eventually joined the Autobots and become the Dinobot Grimstone.
Grimstone has always dreamed of power and the privilege it brings. Despite his hunger for power, however, he has always considered the needs of others before himself. He believes it is the responsibility of the powerful to protect those less fortunate - a belief he intends to aggressively enforce now that he has his own Power Core team.
While it is believed that Grimstone is former Deception Kakuryu this isn't confirmed because there is no information or background on Grimstone's Power Core box to prove that he is Kakuryu. Aside from there being no source of information to prove that Kauryu is Grimstone in many sources of media Kauryu is still shown as an active member of the Deceptions. While Kakuryu is not the smarties member of the Deceptions and is kinder then the rest of the Deceptions he is not shown to be power hungry like Grimstone and although Kauryu kind it is never shown or mentioned about him protecting the weak like Grimstone.
Another difference between Kakuryu and Grimstone is that Grimstone hasn't had as many appearances in media as much as Kauryu. Plus there is some information suggesting that Kakuryu is also the Deception Dino King but despite the information saying that Kakuryu is Grimstone and others saying he is Dino King there isn't anything to confirm that he is either one. The information saying that Kakuryu is Grimstone or Dino King comed from Kakuryu's wiki page while Dino King and Grimstone's pages have nothing to confirm this. Although Kakuryu's wiki page suggest that he is Grimstone or Dino King in comic books, cartoons and other toy lines Kakuryu is still called Kakuryu so there is nothing to suggest that he is Grimstone or Dino King.
So because there isn't much information about who Grimstone is in other forms of media other than the Power Core Combiners toy line not much is known about him and his Dinobot drones. Because not much is known about Grimstone and his Dinobots the other Dinobots such as the ankylosaurus, pachycephalosaurus, parasaurolophurus and the dimetrodon are simply referred to as drones and aren't given any names. Grimstone also shares a few similarity to the other Dinobot Grimstone their similarities are that they are both Dinobots who are also Autobots and are leaders of their own team they also have two members on their team that are prehistoric animals that are not dinosaurs like Swoop the pteranodon and the dimetrodon drone. Another similarity between Grimlock and Grimstone is that their teams have five members.
Because Grimstone is a power core combiner many of the dinobots he combins with are drones. However not all power core combiners are drones but many of them are made of drones.
