Since today is Mar10 day, I decided to do this! Q is Mario. Despite her being the second protagonist, she's the braver one. N is Luigi. Despite him being the first main protagonist, he's more cowardly and doubtful. A, C, I, T, and U are Peach because they all get kidnapped. The Toads are M, O, P, and S because they help N and Q through the journey to defeat E. Yoshi is J because she's the only letter who joins the heroes with a special ability (her tittle). Bowser is E for obvious reasons. Bowser Jr. is Æ. Kamek is Œ. Bowser's minions are Æ and Œ clones because Æ and Œ are E's mutant minions. E would clone them with his letter cloner. Wario and Waluigi are L and R for obvious reasons.
