Suggest characters for the Belly Meme (Patreon)

Since this meme template won the poll I did a couple weeks ago, I'm going to try filling it out this month instead of doing full artworks (besides commissions). So here's the chance to suggest characters, I haven't decided if I'm gonna do one character for all fills or one character for each fill, but the latter seems more probable for the time being. I also decided to have this suggestion post for all patrons as the more character suggestions the merrier.
