I bought a Transformers Crossovers War Machine on clearance awhile back... I was going to use him for a Depth Charge but realized I really needed Cosmos in my collection. I removed the wings and mistransform him to give him more of a bullnose look, and added a face from a misc Power Rangers toy. The chest is from Power Rangers as well, with some heavy mods. I used a hinged LEGO piece to allow it to open, and you can see Cosmos' signal beacon (4th pic) and the vid screen of Optimus Prime (5th pic) as seen in the G1 episode "The God Gambit". The screen is a little hard to see... I had to shoot from a weird angle and it was hard to get into focus. He's a bit big, but I figure Cosmos should be bigger than the minibots, considering he carried around Perceptor, Bumblebee, and all that.
