Nega Nebulus (ネガ・ネビュラス, Nega Nebyurasu) is the Black Legion, under the leadership of Black Lotus. The main goal of the Legion is to defeat the six other Kings and reach level 10 to meet the developer of Brain Burst.
Nega Nebulus was one of the seven Legions that were led by a level nine Burst Linker, commonly referred to as a King. However, after Black Lotus killed the Red King, Red Rider, she took the rest of the legion on an attack on the Imperial Palace. She split her forces into four groups to attack each of the Four Gods simultaneously, but Nega Nebulus was defeated on all fronts. This led to the disbanding of the Legion, and Black Lotus went into hiding.

The Elements is a group of four elemental-themed Burst Linkers who served under Black Lotus until her disappearance. They were the most powerful Burst Linkers of the original Nega Nebulus. The four members are:
Most of them went MIA after their disastrous attempt of defeating the Four Gods of the Imperial Palace, rumored to be the final dungeon of Brain Burst and one of the game's possible "winning conditions." Sky Raker went into hiding, but Ardor Maiden and Aqua Current were both trapped in an "infinite Enemy Kill" status by Suzaku and Seiryuu, respectively. Seiryuu's unique Level Drain Ability also caused Aqua Current to revert to level 1 and lose all her Burst Points but did not lose Brain Burst. Graphite Edge is also in an infinite EK state with Genbu.
As of the end of the ISS Kit arc, all but Graphite Edge have returned as active members to Nega Nebulus.
Latest revelations revealed that Graphite Edge is now part of Great Wall as the First Seat of the Six Layered Armor.
- Like the other six Great Legions, Nega Nebulus takes its name from astronomical phenomena. "Nega Nebulus" is harder to place than the others and translates to "negative nebula," meaning unknown. Also, the Latin word for "nebula" is spelled "nebulas."
