cringe oc idea

Cringe OC idea because I like bad fighting games:
Mortal Kombat character
There's a whole realm dedicated to Chaos (it's called chaosrealm, very creative)
OC would be from here, chaotic by nature.
Entire deal would involve being able to manipulate their body at will.
Primary means would be manipulating weight (how ever did I come up with this)
Constantly shifting between painfully skinny and morbidly obese
Skinny is the "default" whilst obese is used for fighting purposes.
Also able to manipulate other aspect, but mainly aesthetically.
Things like hair colour/length or bodily aspects like breasts or genitalia.
Gender as a concept is completely irrelevant to them.
Having a nonbinary shapeshifter is probably offensive right?
Haven't decided their main look yet.
Outfit would have the concept of being torn and raggy (Due to bursting out of their clothes due to their weight shifting)
Shifting means they can also hide their true weight, which is unknown but implied to be extremely massive.
Would likely be a blob of fuckton proportions at their true weight.
Veeeery basic so far, please tear into this cringe idea as much as you please
