I always liked when Grimlock was a wild card, Conan the Barbarian type like the first two seasons of the cartoon, and the Marvel comics. Somehow, for some reason, they made him super childish for season 3, like a buffoon. Which, I mean, it is a kids cartoon, so that’s fine. Lol, but certainly not my preference. The way he handles the Sharkticons in the movie is always one of my most favorite parts.
