Red Noir, real name Baxter Eberusu, is the main protagonist of the Miraculous Red series. He is the younger brother of Ladybug through his Dupain-Cheng heritage and is the third son of Denise Tourneur, the Metallic Blu Beetle Miraculous user, and Ballard Eberusu III, who has gone missing one day, but is regarded as the mastermind of the Golden Knight Miraculous becoming the villainous Doomsday whose main goal is to take the Red and Rainbow Miraculous to wish for chaos into a new world. Baxter also is the holder of one of the most powerful miraculouses in pairs that specific was chosen to him, the Red Miraculous, the power to create, enhance, and turn anything into the color red, including the Eiffel Tower.

Not only is Baxter the holder of the Red Miraculous, but wields a secondary miraculous called the Brown Bat Miraculous, capable of turning him into Bat Marron, however in the game, Red Noir uses it to combine it into the final form, Gold Noir, which is his finishing move!

As Red Noir, Red Noir has the power of Red Aura, a power that allows him to enhance his limbs to make him stronger during combat and surround himself in a Red-colored aura. He can also summon a new weapon called a Special Weapon, which allows him to create a new weapon to counter a akumatized villain's and exploit their weakness.

Red Noir's voice should be able to sound like Giorno Giovanna's from the Dub version of Golden Wind, but make sure he's very arrogant and egotistical minded, similar to Deadpool, but also keep his determination into becoming stronger.
