Grimlock's toy was originally part of Takara's Diaclone Dinosaur Robo series. When Hasbro imported the toy in 1985 for the Transformers line, its blue pelvis was changed to red and the Diaclone driver mini-figure was dropped.
The original Grimlock changes from a robot into a robotic T-Rex and comes with a red energo-sword, a black double-barreled rifle, and a rocket launcher with three silver rockets.

Sludge was released as part of the second series of Transformers in 1985, transforming into a robotic "brontosaurus". He has a trio of silver rockets, a rocket launcher, a black gun, and a red sword. Like most Diaclone-era molds, Sludge also has a conspicuous driver compartment located in his chest.



Swoop's die-cast metal chest is painted red, which is his Transformers color, as opposed to his cartoon color scheme which was based on the Diaclone toy. Along with his sword, he also comes with two spring-loaded missile launchers, the only Dinobot to have two projectile-launchers.
Swoop is notable for being one of the most fragile Generation 1 toys, and as such commands a respectable amount of money on the secondary market due to the difficulty in finding one intact.
