Waluigi

Waluigi is a recurring character from Super Mario Chronicles. He is the rival of Luigi throughout the series, mostly of his inmatureness.

Default Outfit
Waluigi's outfit includes a purple undershirt under usually dark purple overalls, orange shoes, and a purple cap that covers his short, brown hair. He has a large, pink nose, a thin mustache which is straight (horizontal) and pointed up at the edge, and gray eyes, his eyes being surrounded by light blue rings. He also has long limbs and a skinny torso. The yellow symbol on his hat and gloves is a vertical mirror image of Luigi's "L" which forms a "Γ", just as Wario wears a "W" in contrast to Mario's "M". "Γ" is also the Greek letter Gamma, which is pronounced similarly to "G".

Super Mario Chronicles Arc 1: Chapter 1
Waluigi appears with Wario in support for the Food Eating Contest with Mario. He throws a temper tantrum so inmaturely when Wario lost. Luigi calls him out being a "Inmature Grown-Up Child".
