In Bumblebee and his redeco/retool Goldfire we've got a little microcosm of toy-pushed fiction. The Bumblebee toy was designed to mimick a comics-only design that appeared years back. Later in the comics, he'd be rebuilt into a "Goldfire" version of that same body because the comic had to advertise the redeco/retool. As I type this, I realize no one else is going to care. BUT TOO LATE, YOU READ IT.
The toy is simple enough, and for that it's a fun buy. Back of the car becomes the legs, the sides become the arms and the hood becomes the shoulders. The torso untelescopes to reveal the head, and everything else piles up on his back. It works better as Bumblebee -- my Goldfire has trouble keeping the torso locked together in robot mode.
That's about it.
