>>5671862Grimlock has a number of official releases, including the G1 Masterpiece, classics update, and Generations one inspired by the game, but looks dopey. Similar to Devastator, there's a third party Dinobot war spanning multiple styles and size classes. There is a larger KO MP Grimlock for starters. Some are G1 styled like Toyworld and Gcreations, but are part of a combiner. Planet X Vulcan is probably the best Grimlock this side of MP but it is basically an actual good Generations Grimlock inspired by the game. Fansproject is an updated take with minicon sledgehammers and chainguns. Fanstoys Grinder is basically a bigger and badder MP. There's a Legends build kit from Warbotron designed by Iron Factory, and a painted, upscaled KO on the way. Iron Factory are doing a legends scale War Within Dynobots, and Spark Toys are doing MP sized War Within Designs. You also have a few chibi options as well with Tiny Rex and Dr. Wu.
Pic related is FT Grinder. I don't have the latest Dinobot mega chart that lists them all. I think the best of note is the MP, the KO MP, FT Grinder, Planet X Vulcan, Iron Factory's legends set, and Spark Toys WW, and maybe the KO Warbotron one. Only the first three are G1 focused. The combiners have problems IIRC.
