Geno

Geno is an obscure character who debuted in Earthbound, later appearing in the prequel, Super Mario RPG. Since his debut, he has appeared in many Mother games.

Personality
Geno is a very sad man, often commenting on how he wishes he could be in Super Smash Bros., and insisting they may add him in the future beyond the Mii Costume. He seems very desperate for this, as if it's the only thing on his mind. Despite this, he's not the worst guy around. Very iconic man.

Appearance
Geno looks like a funny puppet, but he's actually a doll. He's got a big nose and dark red eyes. Also a blue hat with some orange things on it and a cape that's also blue and also yellow. His shoes are like brown I guess. He is also bald.

Sans Undertale
Sans Undertale and Geno Earthbound have been friends since Earthbound, where Sans was Ness. Geno originally met Ness because his father, Super Mario RPG Mario, sent him to protect him, but they later became actual friends after Geno travelled with him for a while. Geno still sometimes updates Sans on how his father's doing.

Super Mario RPG Mario
Geno met Super Mario RPG Mario in a forest maze along with Mallow, and they all beat a bow guy and started travelling together and it was cool. At the end of the game, Geno un-possesses the doll, but after the events of the game he possesses it again because he forgot his wallet, now finding out Super Mario RPG Mario's son was out on an adventure so he was sent to join them. Ever since, Geno has remained in the doll.

Masahiro Sakurai
Geno and Sakurai have never met, but Geno hates him. Geno insists he's biased against iconic and relevant characters such as himself, which is why he only got a Mii Costume. He's constantly putting on personas on message boards, claiming how cool he is and how much he hates this Japanese man he has yet to meet.

Lucas Megalovania
Geno meets Lucas Megalovania in Megalovania within the game Megalovania. He was there because he misread Sans' new address in Hometown, so he ended up in Megalovania by mistake. While he was there he decided to join Lucas Megalovania's party for a second but then he left. That was Geno's only interaction with him.

Sephiroth
Geno hates Sephiroth from Final Fantasy 7.

Sora
Geno hates Sora from Kingdom Hearts more.
