Yoshi from Super Mario World
Originally designed to be little more than a creature for Mario to ride, Yoshi’s arrival in Super Mario World changed the series forever. The saddled green dinosaur didn’t just carry Mario, but could launch his tongue as a deadly attack, swallowing even difficult enemies whole. A powerful ally, Yoshi would soon become not just a mode of transportation, but a legitimate character in several Mario titles alongside Luigi and Donkey Kong. Nintendo’s changing designs since then — standing him upright and granting him arms and hands — have made Yoshi much, much more than just a cheerful green dinosaur.
