And here is a list of characters that I don´t know if they are from Nintendo or are from a Third party developer, if someone knows this characters and have the answer can you link me the page from where you got the information.
Muguru-kun - Power Lode Runner (1999 - SNES)
Oni - Power Soukoban (Super Famicom 1999)
Colonel Scott O'Connor - Kabuki Quantum Fighter (Nes 1992)
Kabin - Karkurenbo Battle Monster Tactics
Finally I´m trying to get more research in WTF and Retro Characters because I see a pattern, there is always a Retro Character and a WTF Retro character in every smash, looking like this:
Smash 64
Retro: Captain Falcon
WTF Retro: Ness
Melee
Retro: Ice Climbers
WTF Retro: Mr. Game & Watch
Brawl
Retro: Pit
WTF Retro: R.O.B.
So who would you think will be the Retro and WTF Retro from this Installment and no, I don´t count Little Mac or Third Party Character like Pac-Man for any retro spot.
