CharacterYoshi's IslandYoshi

An infant in a diaper whose crying became an actual game mechanic. Baby Mario shows up in Yoshi's Island in 1995: Yoshi carries him on his back, and losing sight of him sets off that famous countdown. This article breaks down his central role in the Yoshi series, his personality and his promotion to playable hero in Mario & Luigi: Partners in Time.

Baby Mario is the infant version of Mario, one of the most iconic characters in the world of Super Mario. Even though he is only a baby, he plays a major part in several games, most notably in the series starring Yoshi, where he sits at the very heart of the plot. Instantly recognizable thanks to his blue overalls and his red cap, Baby Mario embodies the origin of the mustachioed hero and brings a touch of innocence, humor… and sometimes pure noisy chaos to Nintendo's adventures.

Origin and first appearance

Baby Mario makes his very first appearance in Super Mario World 2: Yoshi’s Island (1995, Super Nintendo). Carried by the stork alongside his twin brother Baby Luigi, he is torn away from him during an attack by Kamek. Rescued by Yoshi, he becomes the green dinosaur's travelling companion, setting off a quest to find Luigi again.

That debut marks the birth of a “baby” timeline running in parallel inside the Mario universe.

• Outfit: blue overalls, red T-shirt, red “M” cap, bare feet
• Personality: energetic, fearless, impulsive, loud but full of willpower
