Marquette Ultraman Mebius (マーケット ウルトラマンメビウス Māketto Urutoraman Mebiusu) is a capsule monster based on the original Ultraman Mebius.
- Height: 49 m (in cyber world)
- Weight: 35,000 t (in cyber world)
- Origin: GUYS Phoenix Nest
Many prototype Marquette Monsters were created in hopes that they would be of use to GUYS in the future to help defend Japan. One of them was a Marquette of Ultraman Mebius himself, in case Mebius was not there to help them (To Mirai's dissatisfaction). When Marquette Zetton went out of control and tried to destroy GUYS's central computer system, GUYS tried to fight back with the Marquette Ultraman Mebius. Unfortunately, the Marquette Ultra was given too many orders by GUYS until it was confused into attacking the Marquette Zetton with his Mebium Shoot, which was reflected back at him in Zetton's signature style. As the real Ultraman Mebius came to the rescue, the Marquette Ultra's Color Timer went out, causing the Marquette to disappear into particles. After Marquette Zetton was destroyed, it is assumed that Marquette Mebius was shelved along with the rest of the prototype Marquette Monsters.
- This is the only capsule monster based off an Ultra.
- Marquette Mebius' defeat is a reenactment/tribute of Ultraman's death in Ultraman.
Powers and Weapons
- Mebius Brace (メビウスブレス Mebiusu Buresu): A copy of himself, he is armed with a Mebius Brace that allowed him to do these following abilities.
- Mebium Shoot (メビュームシュート Mebiūmu Shūto): Marquette Mebius can perform the Mebium Shoot by placing his right palm over the Mebius Brace, then extending his hands in different directions horizontally, and then bringing them together above his head, creating an "infinity loop" before forming the "+" formation. However, it is slightly weaker than the original.
- Mebium Slash (メビュームスラッシュ Mebiūmu Surasshu): Marquette Mebius can fire a tiny arrow-shaped blast from his wrist, like the original can. However, it is not seen as Aide Toriyama told Marquette Mebius to use the Mebium Shoot instead.
- Mebium Blade (メビュームブレード Mebiūmu Burēdo): Although not seen, GUYS confirmed that Marquette Mebius can conjure up an imitation of the Mebium Blade from his wrist.
