Mario's taller brother turned anxious sidekick energy into one of Nintendo's most enduring winning formulas.
Luigi started as the palette-swap second player, then gradually became the patron saint of nervous competence. He shakes, stumbles, and still gets the job done, which makes him feel more human than most mascot heroes ever will.
Example
Luigi's Mansion took a spare brother and turned him into a full franchise lead by leaning hard into the contrast between fear and responsibility.
Why it matters
Luigi proves a character can become iconic by being slightly less confident than the world expects, not more.
