Those horror bishoujo redesigns are fun. I wanna chub up another one...

Korra and/or Asami?

For the second one, here are some characters that I often forget aren't as canonically chubby as people like to draw them...

Some other ones from the years... 🍕

I feel like I don't really know how to come up with OCs, apart from just making obvious ripoffs of existing characters.... but at least that's a starting point.
