Ok so, somebody asked me if MBs can get fat and/or have their appearance semi-involuntarily change over long time periods and I couldn’t give you the whole answer for reasons but I thought I’d post the part of it I could because that was an awesome question.

Hahahaha that is a hilarious question that I never thought about. :p

Um…. I’d say to the latter, yes! They can very much be involuntarily shaped by their environment.

If an Insulator was in a snowy place that threatened to freeze it whenever it liquefied and as such was miserable there it might end up gradually adopting a more snow-like pattern and gaining a more rigid body, and switching to transforming into slush or snow rather than fluid. Alternatively maybe it might gain fur and switch to liquefying into a steaming fluid, depending on the individual.

Can they get fat though. Hmmmmm. That’s a tougher question.

Some MBs, particularly Observers, definitely like to eat stuff. Vontada-Observers like to eat a LOT of stuff, but I don’t see them as getting fat. I do kinda see them as getting gradually more powerful though.

MBs with wider body types are possible and MBs can end up changing to a form with a different style when their qualities and/or perception of things change so yeah, I guess one could get fatter.

So basically, they CAN get fatter but not any way a normal creature would.

Edit (25/06): now I’ve stopped withholding “spoilers”, I can give you the full answer. Contains worldspoilers of course!

I do kinda see them as getting gradually more powerful though so they probably digest food by turning it into aethereal “energy” that adds to them the same way radiation from Totalia and Nanta would.

MBs with wider body types are possible and MBs can end up changing their outward form to a form with a different style when their qualities and/or perception of things change so yeah, I guess one could get fatter.

So basically, they CAN get fatter but not any way a normal creature would. They would have to have like, some big revelation or event happen to them that made them perceive themselves/the world in a way that coincidentally included being fat when translated into a physical appearance. I am not sure what that would be exactly.
