Geno (whose real name being ♥♪!?) is a puppet ally of Mario, who first appeared in Super Mario RPG: Legend of the Seven Stars. In actuality, he is a star being from Star Road, who possessed the body of a doll. Despite only making a major appearance in Super Mario RPG: Legend of the Seven Stars, he has a rather large fanbase.
Geno is one of the main characters in Wario & Geno: Saviour of the Stars. He was after King Dedede because he took over Star Road and scattered the Star Spirits, which is when he met up with Wario who was going to get his money back (and rescue Mona).
His special moves have both power and range, but Geno himself is light and slow. He is also more likely to trip than other characters, especially on ice or bananas. Geno also made an appearance in Super Smash Bros. DS: Rise of the Defeated. He is a very powerful character to say the least. He makes yet another appearance in Super Duper Smash Bros. He was not originally planned to be in the game, but won his way in as the fan favorite.
Geno makes a cameo in Toy Shop on the dolls shelf.
Geno will reappear in this game in the Forest Factory Galaxy. He gives Mario a Spring Mushroom to get past the gears. Geno (along with Mallow) is seen in the game's ending cutscene as one of the people watching the stars.
