Let’s be real. If you walked into a theater in 2017 to watch Transformers: The Last Knight, you probably wanted one thing: giant robot dinosaurs wrecking shop. We’d just come off Age of Extinction, where Grimlock was essentially the heavy cavalry that saved the day in Hong Kong. He was massive. He was terrifying. He was a fire-breathing T-Rex that Optimus Prime had to literally punch in the face to earn his respect.
Then The Last Knight happened.
And honestly? Grimlock became a glorified guard dog. It’s one of those weird creative pivots that still bugs the fandom today. You’ve got this legendary warrior, a literal King of the Dinobots, and he spends most of the movie hiding in a South Dakota scrapyard like a naughty Labrador.
The Scrapyard King: Grimlock in The Last Knight
The movie picks up with the Autobots in hiding. Cade Yeager (Mark Wahlberg) is running a sanctuary for giant robots, and Transformers: The Last Knight Grimlock is basically the "muscle" that can’t stay out of trouble.
It’s played for laughs. Mostly.
There’s a scene where the local police chief is screaming at Cade because Grimlock keep eating his patrol cars. He literally treats a cruiser like a chew toy and has to be scolded into vomiting it back up. It’s a far cry from the "Legendary Warrior" status he had in the previous film. In Age of Extinction, the Dinobots were ancient knights. In this one, they’re just... around.
Actually, "they" isn't even accurate. While Grimlock and Slug (the Triceratops) show up at the scrapyard, the rest of the team—Scorn and Strafe—are just gone. No explanation. No goodbye. They just didn't make the cut.
Why was his screen time so low?
If you time it out, Grimlock has roughly one to two minutes of actual screen time in a movie that runs over two hours. That’s a tough pill to swallow for fans. Why bench your biggest hitter?
There are a couple of theories.
- The Budget Wall: Rendering a giant, mechanical T-Rex with every scale and gear moving in 4K is expensive. Like, "we could buy a small island" expensive.
- The Dragonstorm Shift: Michael Bay wanted to focus on the new combiner, Dragonstorm (the three-headed dragon). To make Dragonstorm look special, the writers likely felt they had to sideline the original "giant lizard" characters.
It’s a classic "new toy" syndrome.
The Mystery of the Baby Dinobots
Okay, we have to talk about the "Mini-Dinos." These tiny versions of Grimlock and the crew appeared out of nowhere at the scrapyard.
They are adorable. They breathe tiny puffs of fire. They snuggle with Izabella. But where on Earth did they come from? The movie never says. It just expects you to roll with the idea that giant metal dinosaurs can somehow produce offspring.
Some fans theorize Cade built them from spare parts. Others think they might be "protoforms" that took on dinosaur shapes because they were hanging out with Grimlock. Whatever the case, their inclusion was clearly a bid for "cute" merchandising, even if it made zero sense in the lore.
Transformers: The Last Knight Grimlock vs. The G1 Legend
If you grew up with the 1980s cartoon, this version of Grimlock feels like a different species. The original G1 Grimlock, voiced by the legendary Gregg Berger, was a dim-witted but arrogant powerhouse who spoke in the third person ("Me Grimlock no like you!").
In the Bayverse, he doesn't talk. At all.
Well, he roars. A lot. But the lack of personality is what hurts. By the time we get to The Last Knight, Grimlock has lost his edge. He’s no longer the rebellious king who challenges Optimus Prime’s authority. He’s just a pet. A big, metal, car-eating pet.
What went right?
I’m not just here to complain. The design is still incredible. The "knight" aesthetic—the spiked armor, the blackened metal, the sheer scale of him—is a visual masterpiece. When he actually does do something, like tail-whipping a Decepticon or charging through a line of TRF (Transformers Reaction Force) vehicles, it looks spectacular.
The VFX team at Industrial Light & Magic (ILM) really outdid themselves on the textures. He looks heavy. He looks like he’s made of ancient, battered steel that’s survived centuries of war. It's just a shame we didn't see him in the final battle on Cybertron.
Actionable Steps for Collectors and Fans
If you're looking to add this version of the character to your shelf, or just want to dive deeper into the lore, here’s how to navigate the current market:
- Track down the Studio Series 07 Grimlock: This is widely considered the best figure of the movie version. It’s a Leader Class toy, meaning it's big, and it actually looks like the CGI model. Avoid the older "Premier Edition" from the 2017 line if you want accuracy; the colors were a bit too "neon green" compared to the movie's gunmetal grey.
- Watch the "Creation of the Dinobots" Featurettes: If you own the Blu-ray, there are some behind-the-scenes clips showing how they animated the movement of the T-Rex. It explains why they went with a "barbaric" feel instead of the goofy G1 personality.
- Look for the "Shadow Armor" Variant: There’s a rare "Shadow Armor" version of the Tiny Turbo Changers that looks surprisingly cool for a small toy.
- Check out the "King Grimlock" Comics: If you're disappointed by his lack of dialogue in the films, the IDW comics give him a much more complex "barbarian king" persona that bridges the gap between the movies and the classic cartoons.
Ultimately, Grimlock in The Last Knight represents the biggest frustration of the later Bay films: incredible potential sidelined for a crowded plot. He’s a icon of the franchise, and even a few seconds of him breathing fire is better than no Grimlock at all.
Just don't let him near your car. Seriously.
