Prominence (プロミネンス, Purominensu), also known as the Red Legion, was a Legion founded by the first Red King, Red Rider, and formerly led by the second Red King, Scarlet Rain. The entire Legion was recently disbanded, with all active members being absorbed into the Black Legion, Nega Nebulus.
Prominence is one of the seven Legions led by a level nine Burst Linker – one of the pure-colored Kings. It was formerly led by the first Red King, Red Rider. However, after his death by Black Lotus, the second Red King, Scarlet Rain took over Prominence after an extended period of warfare. Prominence was also involved in the elimination of the fifth Chrome Disaster because of one of its members, Cherry Rook, acting as its host body. Scarlet Rain worked with the members of Nega Nebulus to take it down, even prevailing through an ambush set up by Crypt Cosmic Circus.
In Vol. 19, the legion disbanded, and all of the members will be absorbed into Nega Nebulus. It was agreed between the two kings, However, it not yet officially announced.
Among the major Legions, Prominence is the smallest regarding the number of members. This could be due to the "warring states"-style period after Red Rider's death; many Burst Linkers left when Scarlet Rain finally assumed command. However, this also means that the current members are a tight-knit group. Prominence has three high-ranked members, known as the Triplex. Blood Leopard, as the Legion's submaster, is also one of these three.
Prominence encourages the viewpoint of "specialization over versatility" concerning Duel Avatar builds, much like Nega Nebulus.
Prominence's territory extends to all Combat Areas in the Nerima prefecture, as well as the Northern Area in the Nakano prefecture.

- As is the case with the other major Legions, Prominence takes its name from astronomical phenomena. A solar prominence is an enormous – sometimes bigger than Jupiter – cloud of fire that escapes from the sun then loops around back to it. Some have even been recorded to have a radius almost as large as that of the sun itself.
- In short story 2, there is a 6v6 battle between Prominence and a legion called Helix. Along with Blood Leopard, Mustard Salticid is part of this team. The other four members are referred to as "Rob," "Simon," "Moss," and "Acon."
