Favorite body type, is it? Hard to say really, all types of bodies are great.
For like a fantasy setting, I do enjoy a huge blubbery figure just pushing the boundaries of immobility, just so close to being a massive immobile mound of fat and heft, still trying hard to waddle about and heave their huge frame around still. And then I also enjoy just a huge mountainous or even astronomical blob towering and looming high above everything, heh.
