Leigi

Leigi is the artificially created brother of Merio. He was created by Weegee and Merio when Merio wanted a brother. Leigi came out, and has been with Merio ever since. Leigi is the slightly weaker, yet slightly smarter and nicer version of Merio. Unlike his brother, who likes Weegee and hates Malleo, Leigi hates Weegee and likes Malleo. Despite this, he still works with Weegee nonetheless. He lives in a mansion he won in a contest he never entered, which he once had to save Merio from. Leigi, unlike Luigi, isn't scared of ghosts. In fact, Leigi LITERALLY eats them for breakfast. He is scared of Pervy Robotnik after a misunderstanding about a "play date".

Trivia:

 * He hates Owli for reasons unknown (like his brother)
