Yoshi

Yoshi is the dinosaur companion of Mario and Luigi, and a member of the Yoshi species. His first encounter with the Mario Bros. was when the Magikoopa Kamek separated the two at birth, and Yoshi met Baby Mario by coincidence; he and the rest of the tribe helped reunite the two brothers and end Kamek’s evil plan ("Yoshi's Island"). Years later, Yoshi met Mario and Luigi again in Dinosaur Land, where Bowser and the Koopalings trapped him in an egg and kidnapped his friends, as well as Princess Peach; as thanks for freeing him, Yoshi aided them in their quest to find Bowser and free said captives ("Super Mario World"). From then on, Yoshi became their ally and friend, and is now loyal and devoted to his saviors. In the “Dimension” saga, Yoshi follows the Mario Bros. primarily as they travel with the rest of the group; he acts as their noble steed, assisting them during their quests, and makes use of his egg-making and throwing abilities during battle.
