Helix Chamberさんのイラストまとめ

This alleged female Charmeleon appears to be a later version of the one found in the files of the final game, having the same pose and the same smaller horn...bump?

@PLDHnet @PokemonGoApp I got this one.

A 4-page manga drawn by Ken Sugimori that was apparently made to promote the Mew distribution in 1996-97. Lisa Hatfield from Pulseman makes a cameo here. Full translation provided by us. See the high definition pages over at our art-posting blog: https://t.co/CjyVLABOhV

Small update today, it appears Grotess' pose and concept were reused for Huntail in Gen 3. Similarly, Ikari seems to have split between Gorebyss and Sharpedo (pose and head fin shape went to Gorebyss, small shark head and position of fins went to Sharpedo).

In honor of Blue... Green... Leaf? being added to LGPE, hi-res artwork of her from Generation 1. First is by Sugimori himself, the second and third are from Mato of Pokemon Special/Adventures.

--NOT REAL POKEMON--

Probably by Junichi Nihei ニ瓶淳一 , published in the Corocoro March 97 issue. In the early days, Corocoro promoted the Pokémon Batoen (ポケモン バトエン, “Battle Pencils”), a rock-paper-scissors-like game with Pokémon moves written on each side of a pencil.

--NOT REAL POKEMON--

Published in Corocoro Comic June 97 issue, probably by Junichi Nihei ニ瓶淳一. This unofficial Pokémon was designed to promote a contest called “Pokémon 2 Idea Contest” where readers were encouraged to submit their ideas for the next Pokémon installment.

Colored concept art for the anime from various sources. Meowth's ears are white like that in a few different instances so it was likely planned to be that way. In Corocoro, Ash was drawn with that lightning bolt hat multiple times so it must have been a late change.

Team Rocket art drawn by Sugimori in honor of their appearance in LGPE. Their designs in the anime changed quite a bit from the concept art, Jessie even has one of the Gen 1 whips!
