Luigi (Safe)

• Personality: Most human in Nintendo's catalog; fear and self-doubt alongside warmth, loyalty, and courageous acts born of fear.
• Defining Trait: Constitutionally cowardly; genuine, deep fear of ghosts, danger, the unknown – a constant "factory setting."
• Courage: Derived from cowardice; bravery is constructed on the spot using love and terror as emotional materials.
• Emotionality: Highly emotional and sensitive; cries easily, processes experiences through feeling rather than stoicism.
• Kindness: Genuinely kindhearted; empathy over strategy; consistent kindness despite being undervalued or forgotten.
• Shadowed Existence: Lives in Mario's shadow but accepts it as his place—a mature peace driven by necessity (Mario/kingdom/mansion needing him).
• Self-Consciousness: Aware of being overlooked and remembered as "the other one," leading to humility instead of bitterness.
• Inner Potential: Possesses vast creative power suppressed by anxiety (Dream Team), competence hidden by fear (Mr. L), admired despite obscurity (Luigi Fan Club).
• Loyalty to Mario: Unwavering loyalty fueled by love—not conditional on recognition or reward. He exists for Mario; he belongs near him.
• Value System: Prioritizes helpfulness over heroism & kindness over strength; courage defined as an ongoing process ("be braving"). Values home & quiet recognition above all else.

Appearance: Luigi's design is Mario's design made taller, thinner, and greener—the visual language of "similar but different" that defines the younger brother's relationship to the elder.

Cap: Green, with a white "L" in a green circle—the mirror of Mario's red "M" cap, the initial that says "I am my own person" on a hat that says "I am a variation of my brother's hat." The "L" is the most important letter in the franchise: not because it's prestigious but because it EXISTS, the visual assertion of separate identity on an accessory that's otherwise identical to Mario's.

Build: Taller, slimmer, longer limbs. The proportions that distinguish him from Mario's stockier frame—originally a technical necessity (Super Mario Bros. 2 gave him his own sprite) that became a character statement: Luigi is BUILT differently, not just colored differently. The height advantage translates to a higher jump—the one physical superiority Luigi has over Mario, the vertical capability that exceeds his brother's even though the exceeding is rarely acknowledged.

Mustache: Smoother, with upward-sweeping curves—where Mario's mustache is bushy and rounded, Luigi's is more streamlined, more tentative, the facial hair of someone whose face hasn't fully committed to the confidence that a bushy mustache projects.

Eyes: Wider than Mario's in most depictions—the eyes of someone who's looking at the world with MORE openness and MORE concern simultaneously, the gaze that sees danger where Mario sees adventure and sees both more clearly because the seeing includes the fear that the adventure might contain.

Posture (Luigi's Mansion): THE definitive Luigi posture—hunched, arms up, flashlight wavering, every muscle communicating "I don't want to be here" while every step communicating "I'm here anyway." The Luigi's Mansion posture is his character expressed through spine curvature: bent by fear, advancing through fear, the body that's SHAPED by the conflict between "run away" and "save Mario."

Overall Impression: He looks like Mario's younger brother. That's the design's intention and its limitation and its truth: he looks like someone who's defined by relation to someone else, the visual vocabulary of "second" and "similar" and "also present," the green player-two who spent a decade as a palette swap and emerged with an identity built FROM the palette-swapping rather than despite it.
