Series: Generation 1
Function: Dinobot Commander
Alt Mode: Tyrannosaurus rex
Height: 12cm, drop to 10cm if you stand Grimlock in the pose later decided to be the correct pose for this animal. Length: 18cm (or 20 if he lifts his tail) Width: 8cm
Well, as mentioned above, Grimlock is an old-school style T-rex, that is he drags his tail. Of course this toy was developed in the 1970s, way before the scientific community decided the T-rex runs like a Velociraptor. It doesn't matter too much though, since Grimlock _can_ walk like a "new" T-rex anyway. Although if you're show/comic accurate, you can keep him as a tail dragger.
Anatomy aside, Grimlock is a pretty show/comic accurate Dinosaur. His "arms" move, as do his legs, and as an added bonus so do the claws on his feet. His head moves and his jaw opens - to reveal a moulded laser where his tongue would be if he had one - which is a nice touch. Being a Diaclone toy, Grimlock has a few little things like that which later TFs missed, such as the moulding inside his Dinobot neck (basically his neck is transparent and inside there's moulded gold chrome plastic. His Diaclone cockpit is on his back (in both modes actually).
He's basically grey, although his arms and tail tip are chrome silver, underbelly (robot chest), inner neck and claws are chrome gold (yes, that's right, two colours of chrome), and his Diaclone cockpit is a smoky transparent affair. Oh yes and he has red eyes. Overall it's a great dinosaur. The only drawback is that he can't hold a missile launcher (Slag, Snarl & Swoop can).
TRANSFORMATION TO ROBOT MODE
Flip back the head/neck, the T-rex chest splits apart and fold back to form his "wings". Split the tail tip apart and fold the halves to the sides of the tail. Swing the underbelly/legs up to where the T-rex chest was (so that the head is level with the top of the gold chest). Swing the tail over to form the lower legs, split the legs and push them out and up to transform the waist. Slide the wrists towards the shoulders (the T-rex legs become the arms), and you're done.
Height: 15cm Width: 12cm wings
Again a fairly show/comic accurate toy, retaining all the major features in the TF media. OK so strictly speaking the show and comic both retained his wings (although the dino head seems to disappear into subspace often). Me Grimlock say me have head very similar to cartoon.
The grey takes a back seat here. His limbs are grey (black hands), black thighs & waist - OK the waist is red in the middle and black on the sides - gold chest and black head.
He's not without his problems, though they are small. His head is a little far back, although we're not talking helipad on front of his face on his shoulders. Basically it sits at the back of his shoulderpads. Also, his arms are maybe a centimetre too long, but you only really notice this if he's standing to attention with his arms by his sides, but since Grimlock isn't one to follow orders, you've already moved his arms into a slightly forward, more natural pose, anyway, right? (c8
Other than those two minor flaws, he's a well proportioned toy. He has a little bit of a backpack but the wings look cool and he has no trouble standing (unless you have a toy with dodgy knees), so I wouldn't really rate the backpack as a negative.
He can move his arms on swivels as most G1 toys can, and bend his knees. Other than that he's a statue. You can position the wings to a swept forward or swept back position, but it's not really a poseability feature as such.
There was one version of Grimlock with a notch on the back of his dino head and one without. I _think_ I have the former, though I'm not sure.
He was released again in G2 in Silver, Blue & Turquoise. The biggest differences (colours aside) were the loss of the rubsign and the gaining of a G2 Autobot Stamp. The supporting colours remained the same in Generation 2, with only the main colour changing.
A good toy, one I certainly recommend getting. Grimlock has a few little problems, but nothing that gets on the nerves. And considering how pivotal the character is in both the comics (where he assumes command) or the movie (he saves Hot Rod so he can light the darkest hour), a must for any collector who digs collecting characters. I'd give this guy 8/10
