Rad, Jackpot & Kick-Off all seem like sports cars. Rollout a bulldozer or jeep. Skyfall a fighter jet, no idea on Mainframe but I did a custom from WFC Blaster as an armoured research computer. Tread shot a tank, Krok has been made into a jet but I think a rally car suits his sports persona better. Banzaitron has been a boat, a tank and a sports car. Personally I like the black sports car; think it suits the secret police persona from IDW well. Axer looks a sports car but I prefer motorcycle. Gutcruncher seems a tank but I think I'm gonna get titan megatron & turn him into gc so he's now a triple changer than incorporates his jet too. Slicer I'm pretty sure is a blue Wheeljack. Opinions?
