“I know! We should team up! Come on! Hop on my back!” — Yoshi , Super Mario Galaxy 2

Yoshi (sometimes specified as Green Yoshi) is one of the heroes of the Mario franchise, an ally of Mario and Luigi, and the protagonist of his own franchise. He is a member of the Yoshi species and has aided his brethren in saving their homeland on multiple occasions. In his youth, Yoshi managed to rescue and protect Baby Mario and Baby Luigi from the wrath of Kamekand the Koopa Troop. According to Super Mario RPG: Legend of the Seven Stars, Yoshi is one of the few members of his species who can speak the language of the other characters, though it seems that this is not his first language, since, as in other games, his statements are translated through parentheses. In the Mario franchise, he is a major character and often acts as a steed for Mario and other protagonists, while in most of the Mario sports and party games, he is a playable character on his own.
