Maroon Balloon (マルーン・バルーン, Marūn Barūn) is a Burst Linker.
While he was catching up with Orange Raptor, he was asked if he knew anything about Glass Monarch, which he did. After Skazka Priskazka was formed, they asked him about Glass Monarch, and he asked for a battle from their junior members Aluminum Valkyrie and Iris Alice before telling them. He easily defeated them.
After a day of strategizing, Aluminum Valkyrie and Iris Alice were able to defeat him.
Maroon Balloon is a duel avatar that looks mostly made of balloons. His torso, left leg, and right arm are all balloon-like, with a balloon sash wrapped diagonally across his torso. His right leg looks like a standard duel avatar's leg, and his left hand is gloved. His head is also enclosed in a balloon, which he has to pop before consuming anything. He is vulnerable to fire.
