Luigi

Luigi is a character from the Super Mario Bros. video game franchise. He is Mario's younger brother who first appeared as a palette swap of him in the arcade game Mario Bros., but gradually evolved into his own characterization and design over time. He usually stars as the second player's character in the 2-dimensional side-scrolling Mario games, but has also accompanied his brother in many other types of games, even getting his own starring role, Luigi's Mansion, in 2001.

In terms of Christmas-related appearances, Luigi starred alongside Mario in the Christmas episodes of the franchise's animated series - "Koopa Klaus", "Santa Claus Is Coming to Flatbush", and "The Night Before Cave Christmas".
