Idk how Ultimate upgrade would look, since he already has the power to shapeshift.

Ultimate Ghostfreak would probably be more muscular than Zs'Skayr and maybe have arm like tentacles coming out of his chest and sides.

I can't Imagine that Ultimate Heatblast would be too much different from the regular version, maybe just a blue version of Ben 10k's Heatblast.
