Oblivion

Oblivion is the title given to the leader of the First Sons. Several members of the First Sons possess it at one point or another.

Torn: Origins
Oblivion is a boss in Torn: Origins. He is the last of six bosses the player must defeat, appearing in the mission 3.5 Cusp of Victory (Good) or 3.5 Feel the Evil (Evil). The player can pick the ending of Torn: Origins, by playing either the Good mission or Evil mission. In the Good ending, A01 infiltrates the First Sons' base of operations in Old Evan, and defeats Oblivion and the Armed Reactor Collider, the First Sons' mega doomsday device. In the Evil ending, however, A01 defeats Oblivion and claims the throne for himself, becoming the next leader of the First Sons, the next Oblivion.

Torn
Oblivion is a boss in Torn. He is the last of four bosses the player must defeat, appearing in the mission Facing Our Destiny. He is the leader of the First Sons. If the player played Torn: Origins before Torn, and chose the Evil ending, then the Oblivion the player is facing is actually A01. However, if the player played Torn: Origins before Torn and chose the Good ending, then the Oblivion the player faces is just another First Son who climbed the ranks after the events of Torn: Origins.

Appearance
Oblivion is a modified First Son soldier with diamond armor and dual swords. Oblivion can be defeated with about 15-20 fully-loaded shots from your Pistol, or about 30 hits from the X.I.A. Wand 420 (Torn) or X.I.A. Melee Wand (Torn: Origins). In Torn, upon defeating him, the player will earn the Achievement Living in Oblivion.
