This is just a thought

I got by listioning to the Theme song of the late new Iron Man cartoon

witch ROCKS XD

the idea for this is

ChaosCroc find a way to Robotisizie Runnic But the Devil Armlet armor of his Soul family, comes out trying to stop it but it can't.
so it controls the energy evoleing it self and it can turn Run into a robot or back anytime Run wants.

XP the 3 spikes on the back of his head are pulled in so the back of his head just round no spikes when his Robotisizie ^^;
