Halloween // Villain costume ideas for a chubby/fat man

My family is having a halloween party this year(we've done this for a few years). Mostly family and some friends. The theme this year is villains, and I'm having trouble with ideas. I've got plenty of time but I wanna plan ahead a bit. I'm a dude, overweight but not obese(although wouldn't be opposed to dressing up as an obese character). Last year, for instance, I dressed up as dennis nedry from Jurassic Park(the theme was 90's). I'm not as fat as newman, but I'm chubby enough that it was fine. I'm not super concerned about looking like the character apart from size tbh(I have long brown hair and my costume last year did not hide that). I'm also not looking to do anything elaborate in terms of makeup(preferably none if possible.) Right now, the penguin is my number one pick. Not colin farrells portrayal, obviously, talk about elaborate makeup. I know dressing for halloween is just for fun but if I were to dress up as a character who is significantly thinner than me I'd be self conscious the whole time. Does anybody have ideas?
