History of Protometon

Overview

Protometon, Nexial Hijacker, is the Vex boss of the final stage of Terminal Overload. When it loses a third of its health it becomes invulnerable and summons three Oracles that must be destroyed, and it repeats this at the next third. Sources disagree on the order of the later bosses in the stage, such as a Psion or Vex Minotaur.
