I just have one, but considering his engineering, the funniest thing i can think about is using extra leg parts to get a diatrain or a larger base mode. Except for that, it's a stand-alone piece, if you don't want to swap parts with the diabattles models. But i've found a way to get a mechagodzilla looking thing from the warudaros rapto-head. Please ignore the mess, i didn't sleep last night to finish a job and i dropped some ashes from my cigarette taking this picture, because i'm so tired my hands are shaking. P.S. The movie is a pathetic thing with zombie nazis on a snowy mountain. Poor choice to take a break.
