Luigi from Super Mario Bros.
Some might claim that since he is technically included in the name Super Mario Bros., Luigi doesn’t fall under the sidekick title. But from his older brother Mario’s first appearance, the pecking order was clear. Originally a copy of his older brother, simply swapping the red color for green, Luigi soon emerged from the shadows and created his very own personality. His blend of courage and cowardice made him infinitely more relatable, but by overcoming the odds to become a star in his own right, we can’t help admire the best role model a younger brother could ask for.
