You might have seen it passing by, but here's a collection of characters from SaltyBet and SpriteClub. Why do I bring this up? Well there's a few Pokemon characters there.
But since you probably don't want to take a look at it all, I might as well just bring the characters to you.
First is Ghetsis, listed as Dennis: https://onedrive.live.com/?authkey=!ANB73Grv5LJeidI&id=6C4BBC4DFBC3097E!5153&cid=6C4BBC4DFBC3097E
I believe this edit just fixes his palette for 1.0 or something along those lines.
Then there's ZZAZZ Bulbasaur: https://mega.nz/#!4zonAYqA!gOt4nq2BFx8ZcEP6j4jQwRtjXIcja3qHSUOURzmkpMY
He's cheap. Explodes and the other person di-faints.
And lastly there's Buried Alive: https://mega.nz/#!Uyxh0TCT!EWZm9j1-jAx8LSuEklz89PemGBwLlviqpDZYMtO0QgU
Didn't add it to my roster. I already have a "Creepy"pasta character in Sonic.EXE by Pizzasause so I didn't feel like I needed it.
And if you really want a reason to look in that collection, there's some neat TouHou edits.
EDIT:
Just came across this A.I patch for Terui's Weezing by Hyde233. It came in a pack. Here: https://drive.google.com/open?id=1OFIXDrYPgSUdzc1AO9D2hD-ZEwKQOTxL
Also here's a Genwunner Game Boy themed Charizard palette by TOMMY Attacks!: https://gamebanana.com/skins/161988
