Deliberately sent into dimensions by the Apothicons, it was first discovered by miners of Purgatory Point and is later discovered by Dr. Ludvig Maxis with his newly established Group 935 in the original timeline, and was discovered by the Germans during World War I in Northern France in Dimension 63.
It was extensively used by Group 935 in experiments conducting at secret facilities. The first meteor discovered was at the Rising Sun facility in Japan, in the map Shi No Numa. Meteor fragments can be found in Kino der Toten, Call of the Dead, Shangri-La, Origins, Der Eisendrache, Zetsubou No Shima, and Revelations. In the original versions of the original Black Ops maps, said meteors are red in color, emit strange noises, and have electrical pulses flickering across their surface. Origins' meteors are green in colour. Shooting them will cause the characters to react with quotes relating to them.
Element 115 was used to create the zombies as one of its side effects was the reanimation of dead cells. The zombies were to be used as super-soldiers by the Germans. After creating them, the Germans realized that they were uncontrollable and would lead to mankind's destruction. The Ray Gun, the Pack-a-Punch Machine, the Perk-a-Cola machines, the Wunderwaffe DG-2, and other various Wonder Weapons are all powered by Element 115, along with the teleporters. It would appear Element 115 can also control the zombies, as the Focusing Stone is a shrunken-down meteor that Richtofen claims will let him control the world.
In Call of Duty: Black Ops 4, Primis and Ultimis' mission are to banish everything that 115 has ever affected to the Dark Aether. They succeed in this, and the Zombies, Apothicons, 115-corrupted universes, as well as every piece of Element 115 in existence are sent there forever.
In Call of Duty Online, Colonel Harker mixed Element 115 with Nova 6 to create dirty bombs.

This version is also seen in the remastered versions of maps seen with the original look of 115. It is unknown whether 115's color changes due to different dimensions.
