First of all, you know how physically strong women look in real life, right?
You also know, that Oda draws many characters who have a bad personality as ugly?
You also know how Big Mom looked when she was younger, right?
You also know Odas sketches of the strawhats as 40 and 60 years olds, where you could see, how they would look like if something went wrong in their life? This would explain Big Moms look.
Last but not least, you know characters like Carrot, Smoothie, Yamato, Khalifa, Stussy, Tashigi, Kuina, Ulti, Belo Betty…
Why are you bodyshaming Big Mom tho?
If being obese is something women celebrate, than Big Mom is superhot!
