Pauline from the Pokemon manga "Pokemon: Reburst". You may probably have heard or read of a manga where the trainers fights instead of the pokemons by fusing with the choosen pokemon. That's the name of the manga and its quite interesting, isn't as goofy as it sounds. Because the manga is in black and white, there isn't an accurate color pallete, Pauline only appears in one of the colored covers and her actual colors are supposed to be red/crimson like but i didn't like it that much so, i used the collor pallete of the Koikatsu Card created by Nak, the nose, mouth and eyelashes also are inspired by his card.
