Yoshi is a dinosaur-like creature who appears in the Mario series and is Mario's sidekick, as well as the tritagonist in many games. His debut was in Super Mario World. He later had his own series with several platform and puzzle games, including Super Mario World 2: Yoshi's Island. However, Yoshi does still appear quite frequently in the Mario series. The Yoshi series includes characters from the Mario series (usually as their baby forms) as well. He has also appeared in many of the spin-off Mario games, such as Mario Party, and Mario Kart series as well as in other various Mario sports titles.
