Wow, that's a sweet pic there. Really shows how Bumblebee is supposed to be huge in comparison to us (I never get that sense when I have him with the other transformers).
What Bumblebee is that?
That's Classics Bumblebee.
He's also mis-transformed in that picture. The doors on his arms should be rotated around so that the wing mirrors are near his elbows.
I think that's done on purpose. He looks more like the Bumblebee we all know and love this way.
