Luigi as Papyrus from the Undertoad AU, standing tall and proud with a confident smile. He wears a green scarf fluttering in the wind, his green hat sharp and clean, and white skeleton-style armor with green accents. His posture is heroic—one fist clenched at his side, the other raised as if ready to catch or challenge. The snowy Cool Cool Forest stretches behind him, with Mario-themed elements like ? blocks and Goombas partially covered in snow. The art style blends pixel art and vibrant cartoon colors, capturing Luigi’s determined and hopeful spirit as the ambitious Royal Guard captain

This version of Mario is quiet, detached, and cryptically humorous. Unlike the heroic, upbeat Mario from the main series, Undertoad’s Mario is haunted by knowledge of resets and timelines, speaking in vague riddles and bad puns. He cares deeply but hides it under layers of laziness and sarcasm. He watches over the underground paths not as a hero, but as a reluctant guardian with a sense of duty.

Luigi is a major character in Super Mario Bros. Z, a fan-made crossover animation series by Alvin-Earthworm. He is Mario's younger brother and one of the central protagonists in the series. Despite often being overshadowed by Mario, Luigi proves himself as a capable and courageous fighter. He plays a critical role in the team's efforts to stop Metallix and the other antagonists threatening the Mushroom Kingdom. Known for his agility and use of power-ups like the Cape Feather and Blue Shell, Luigi combines humor, heart, and heroism in the SMBZ universe.

In a world where the Mushroom Kingdom collides with high-octane anime action, Mario is no longer just the cheerful plumber we know. Transformed by intense training and the power of the Chaos Emeralds, he becomes a fierce warrior ready to face threats far beyond Bowser. This version of Mario, inspired by Super Mario Bros. Z, channels raw energy and determination, standing as the last hope against overwhelming destruction. (Become anyone you like)
