Wario

Wario is a recurring character from Super Mario Chronicles. He is the rival of Mario throughout the series, but in sometime Wario will have a change of heart towards Mario, though it isn't confirmed when this happens.

Default Outfit
Wario wears a plumber outfit similar to that of Mario, Luigi, and Waluigi. Unlike Mario and Luigi, his outfit has some details not shared with his counterpart, Waluigi. He has a white streak on the rim of his yellow hat and has white buttons on his purple overalls instead of the usual gold the other men wear. Additionally, the blue W on his cap sticks out of the white spot it is displayed on. Wario's primary color, yellow, is an opposite color of purple, Waluigi's primary color, on the RYB color model, and he wears a T-Shirt as opposed to the other's longsleeved shirts. Wario also wears green shoes with a brown sole that are pointed like an elf's shoe. His gloves are white and wrist-length with his W emblem printed on the forehand.

Super Mario Chronicles Arc 1: Chapter 1
Wario enters with Waluigi in a food eating contest in which he challenges Mario and lost. When Bowser appeared, it was revealed that Wario has a big hate towards him as well. This could be a possibility that Wario could ally Mario in the future.
