Although we are somewhat limited in customizing our MC characters' looks, we at least have the fine G1 redeco tradition to fall back on. We can kinda-sorta mimic the looks of dozens of other G1 characters using the already available chassis selection. Here are some ideas. Optimus Prime Chassis: Inferno, Grapple, Hot Spot, White Magnus. Bumblebee Chassis: Cliffjumper, Windcharger, Hubcap, Tailgate, Wheelie. Ironhide/Ratchet Chassis: Brawn, Gears, Hound, Huffer, Trailbreaker, Hoist, Outback, Rodimus Prime Jazz Chassis: Bluestreak, Prowl, Streetwise, Smokescreen, Nightbeat. Sideswipe Chassis: Mirage, Sunstreaker, Wheeljack, Tracks, Hot Rod. Warpath Chassis: Grimlock, Scattershot I know those are just Autobot ground vehicles, and there are countless more possibilities. But I think it's cool that it gives us a chance to make the MP feel more G1.
