I like that her fat is both a hindrance and a help when it comes to combat. More mass to throw around, more inertia to be had, but also a potential source of new vulnerabilities!

It's honestly been so long that I can't remember how much she grows over the course of the story (or if she ever really does grow past this size on a more permanent basis), but I do like the nods to the risk that she may very well eat herself into a higher weight bracket --- truth be told, part of me is hoping for it.
