Corneius Kopassus is the Vice-Chairman of Majestic-12.
Corneius Kopasses was presumably born to a wealthy family. At an unknown point, Kopassus created the Kopassus Shipping Group, a shipping company that would eventually become the largest in the world.
Later, Kopassus was invited to join Majestic-12, a group of twelve of some of the richest men in the world. After several years of membership, Kopassus eventually became the group's vice-chairman.
When Majestic-12 decided to enhance their overall fortunes, they began planning to initiate a new Cold War, which their individuals businesses would benefit from and improve their wealth. Through contracts that both Kopassus and Jonathon Killian had with the U.S. government, they discovered a pair of top secret American projects known as Kormoran and Chameleon, which involved disguised battle tankers and clone missiles respectively. By taking over both these projects, M-12 could make several western countries believe they had been hit by terrorist missiles.
In the course of their planning, M-12 discovered that a few individuals could upset their plans due to certain skills or knowledge that they possessed, and so they decided to start a bounty hunt to keep them from doing so. It was soon decided that Killian's Forteresse de Valois castle would be used as the verification point where the heads of the targets would be brought for assessing by Monsieur Delacroix, whom M-12 had worked with in the past.
Among the fifteen targets was Shane Schofield, a U.S. Marine with a reputation for succeeding against the odds. Unsettled by this, Kopassus and M-12 decided that they would arrange a sham mission as an ambush to increase the chances of him being eliminated.
Shortly after the hunt began, Kopassus and the other members of Majestic-12 engaged in a telconference to discuss the current happenings of their plan.
Ultimately, however, Schofield managed to disarm the Chameleon missiles and arranged for the U.S. government to bring down the Kormoran tankers, foiling Majestic-12's plan.
Soon afterwards, Kopassus apparently suffered a fatal heart attack in his sleep, however, having been targeted for assassination by the U.S. government because of M-12's plan, it is clear that they staged the death to appear natural. In the aftermath of his death, Kopassus' heir inherited his company and wealth.
