This is an attempt to visualize the weight stages of a game I recently created called "PWGG" using charizard. (He is male, but that doesn't really matter.) It's a little late, but spoiler alert!
I decided to cut the tail and wings as they seemed to be getting in the way.

Below are comments on some weight stages:
Massive: This was bigger than I expected, so I decided to split it into parts. The reason the original description only says "big" is because it comes from some manga(I forgot what it is from). I didn't explain it because it's so big that I don't even need to explain it.
Snorlax-like: Certain turtle says that calling something that's too blimp a Snorlax is an insult to Snorlax.
