A bit of a happy accident while mixing spare Kreons together:
- Spinister's head and helmet
- Sunstorm's torso and hands
- Waspinator's arms, legs, and arms
- Crankstart's tire (or any Kreon's tire; but if you're like me and don't "transform" these guys you get 2 'extra' tires from Crankstart)
I suppose you could use Sunstorm's preexisting chest details for Brawn, it's not too totally far off.
I may go and paint the helmet a proper shade of gray, but I'm quite pleased how it turned out.
