Not a Transformer per ay but I got the idea after reading the TF GiJoe crossover books. With Cobras hands into cybertronian tech they would of course upgrade the B.A.T.S. My BAT has 3 modes the first is your basic BAT, read yto get shot and do as its told. Phase 2 is to use the bike to make into armor. Phase 3 combined teh BAT with the bike for extra power and it also doubles as a partner for whomever is the rider. I forget the name of the toyline that I got him from but he was one of my usefull fodder figures as I also used his head for a Samus Aran!
