I'm sure some people have had this idea due to the vehicle form as well as various details in the torso that are reminiscent of Prime, most notably the pec windows and ab grille(s).

This is just a quick digibash. Unfortunately, the Voyager head shown here is way to big for the actual toy. Maybe the FAB Prime's head? Anyway, I think it's a cool idea. I might try it once Salvage comes out.

 

ha! I like it man, do. good job on the bash, and the idea actually works.

 

Weird! haha.

Sexy legs there, Prime!
