Going to go with Cheetor. Best of the available selection.
Movie Bee and Proper Bee are very different. I liked G1 Bee (well, Goldbug) in the comics, and he was always there in the cartoon, although I never had much of a fondness for him.
I have to say though, "the Wolverine" of TFs, at least in story terms is Grimlock. BB is more like a Spider-Man (although that might just be the voice making me think that).
assembling a Neo-G1/TF:TM cast. Please PM if you have (or know of) the following at a reasonable price: Classics or Henkei Astrotrain, Ramjet, Sunstreaker, Sideswipe, Blurr, or 3rd Party Motobot Arcee, iGear Ratchet and Ironhide.
Also looking for Universe Repugnus and Overbite, Frostbite and Longhorn and any Webdiver toys.
