Robot Mode: Bumblebee has barely changed from his original incarnation, still a little black-and-yellow guy so adorably cute you wanna hug the stuffing out of him. His face is very much like that of his TV incarantion (unlike the original toy) and his posability is actually quite good for a G1 toy, he can move his arms more or less freely and has independent feet. His Pretender shell is one of the better ones I've seen. It's a brick except for the arms, but the detailling is nice. All in all a decent robot and Pretender mode.
Alternate Mode: What else could Bumblebee be but a Volkswagen Beetle? It would be heresy for him to be anything else. No complaints about the vehicle, it looks as realistic as a plastic toy car can look. Bumblebee's smaller weapon can be mounted on top.
Remarks: Unlike some of the other Classic Pretenders (Grimlock, Jazz, Starscream), this version of Bumblebee is actually an improvement when compared to the original. Better looks, more posability, and generally just a good piece of work. Granted, the whole Pretender gimmick isn't everyone's cup of tea, but I prefer this Bumblebee over the original.
