Grumpy from Once upon a Time (Picture
) Technically he is a drawf, but he is still around the chunky/robust side.
(As you can tell, there is quite a few big guys from Game of Thrones series! so sorry for listing many of them lol they are all nobles too, with a couple being former warriors)
There is also Shrek of course, and if you feel like going for it and "ugly-fying" yourself, there is Fat Bastard from Austin Powers. Then there is Peter Griffin from Family Guy.
I hope that helps a little bit. Best of luck!
