>>57800994 (OP)I have a theory about Jasmine
That just like the first versions of Pokรฉmon games, where the Sprites were made first and then the artwork later, thusly also up to gen2.
Ken Sugimori most probably didn't pay enough attention to Jasmine's Sprite and drew her design a bit older.
If you look at picture related you can see the head-to-body ratio between these sprites, from Oldest to youngest, and you can see how Jasmine has a rather larger head and smaller body compared to the other sprites.
So my theory is that when she was designed was to be sort of a eastery-egg type of character: a kind young girl more concerned more about the health of her Pokรฉmon than battling, yet driving you to lower your guard before this little girl absolutely wastes your ass with her Lv35 Steel noodle, that is also a higher level the next gym leader's tops Pokรฉmon.
I wish the original design had been kept or fixed to the original concept instead of making her even older in the remakes, it kinda defeats the purpose of having you to do chores for that little girl you expect to beat in a blink once she accept to fight you!
