A Primus l'Cie has gradually lost his humanity over his near-hundred-year life, leaving behind only absolute obedience to the White Tiger Crystal and nothing else. Now that Marshal Aulstyne has taken the Crystal hostage, however, Nimbus answers only to Cid. He hides his face and his emotions behind an intimidating mask, and many in the army find his extremely taciturn nature to be unsettling. In combat Nimbus generates a portal in midair and unleashes arrows of compressed light. He occasionally compresses this radiant energy to wield as a sword.
Nimbus is a non-playable character in Final Fantasy Type-0. He is a Primus l'Cie of the White Tiger Crystal, a taciturn and enigmatic. He has fought many l'Cie in the past and lives only to fulfill the purpose given to him by the Crystal.
After Class Zero defeats Qator Bashtar in the battle for Togoreth Stronghold, Qator is forced to fall back, leading to Nimbus being deployed as a final resort. Rubrum's forces are ordered to fall back as Lord Zhuyu, a l'Cie of the Vermilion Bird Crystal, is deployed to face Nimbus. Being the first l'Cie battle in over five centuries, the aftermath of Zhuyu and Nimbus's clash obliterates the stronghold and all but erases it from the map.
When Class Zero infiltrates a weapon manufacturing plant in the Militesi capital Nimbus confronts them. He unexpectedly appears to strangle the party leader as a warning should they stand in his way. Following the defeat of empire's newest magitek armor, Brionac, however, Class Zero battles Nimbus, but he easily overpowers them even if he is not fighting with his full power. The battle is interrupted by the announcement of a ceasefire, signalling the arrival of representatives from Concordia and Rubrum. Nimbus retreats.
When Finis arrives, Nimbus brings Cid Aulstyne to the site where Tempus Finis will begin. He is implied to have taken his own life and entered crystal stasis afterwards.
Nimbus uses optic weapons like light rays as his weapon. From the sky, he can fire torrents of light into the ground, and penetrate targets with condensed beams of light.
Nimbus is fought during the mission Operation MA Demolition. He is at Level 142, and it is impossible to win this fight. Even should one whittles his health to 1%, it will stay there until he tires of the fight. Although the battle will end normally if all party members are KO'd, it is also possible to avoid Nimbus's attacks for three minutes until the battle ends. This strategy is required to obtain an S rank for the mission.
In Final Fantasy Type-0, Nimbus is voiced by Junichi Suwabe in the Japanese version. He shares his Japanese voice actor with Tseng from the Compilation of Final Fantasy VII and Seymour Guado, Jassu, Zanar, and the Hypello race from Final Fantasy X and Final Fantasy X-2.
Nimbus is Latin for "cloud." It is also a name for the cloud's type from which it rains. This could be a reference to his power, as he is often seen projecting penetrating rays to decimate his opponents in the battlefield.
