I was trying to think of ways to create a PC that can go Colossal, and the only ways I can think of are:
-Synthesist Summoner with the Huge Evolution UMD-ing an augmented Expansion Power Stone* to increase size by two size categories. (*or any other Psionic Item that can produce that effect)
-Synthesist Summoner with the Huge Evolution and a Vitalist cohort (or other PC in group) with Expanded Knowledge(Expansion), since Expansion is a Network power for Vitalists.
Any other ways?
