Doopliss
A duplighost who has been causing trouble at Twilight Town, turning everyone into pigs and stealing Mario's identity and teammates, leaving Mario his shadow. His base of operations is Creepy Steeple. To find out what his name was, the player had to team up with Shadow Siren Vivian to do the same thing the characters did in Rumpelstiltskin: guess Doopliss' name. The only thing Mario and Vivian were missing was the letter P. After getting the letter P, they guess Doopliss' name and Doopliss flees back to Creepy Steeple. While battling Doopliss, Vivian discovers she joined Mario's team, she does a little time to think it over and joins the team, because Mario treated her a lot nicer than Beldam and Marilyn. Upon defeat, Doopliss surrenders Mario's identity and teammates back to Mario, wallows in humiliation and joins the Shadow Sirens for revenge. He becomes a lot nicer at the end of the game and pursues a career in acting.
