Waluigi is an oft-recurring character in Brawl in the Family. Unlike most of the characters, who retain their in-game personalities, Waluigi is represented as a strange, creepy, and ugly person. Waluigi often uses his memetic catchphrases "WAAAAA" and "TOO BAD. WALUIGI TIME"; these phrases first appeared in his comics and have been used in the BitForums and in Internet culture.
In his own inane comic series, Waluigi in the Family (which Waluigi intermittently injects into BitF as April Fools' jokes), he is able to possess other objects to make them look and behave like himself.
Few people aren't creeped out by Waluigi. These people are Daisy, Eario, and, of course, Waluigi's brother (cousin? friend?) Wario.
Waluigi is currently trapped in an Assist Trophy as a result of the other characters' shock at hacking their games.
Brawl in the Family Character Description
Hide your daughters and your modern art: Waluigi’s in town!
Waluigi is a poorly-understood individual who has difficulty fitting in with others. His only friend in the world (aside from his brother Wario) seems to be Daisy, who has more patience and compassion than even Waluigi is capable of wasting.
Sometimes, Waluigi goes on some short-lived adventures. This isn’t common because it quickly becomes tiresome.
Waluigi dislikes many things, but he especially dislikes Luigi, musicals, and Brawl in the Family. He enjoys dancing by himself and relaxing in massage chairs.
