The Haimatsu Power Suit, also known simply as Power Suit, or HPS, is a heavily-armored deep sea diving suit manufactured by Haimatsu and used by PATHOS-II staff to protect themselves from the crushing pressure in the Omega Sector.


As the name suggests, Power Suits are powered exoskeletons, containing machinery that amplifies the wearer's movements and enhances their effective strength. They were developed from modern atmospheric diving suits, of which in the early 21st Century had a maximum operation depth of 700 meters (a pressure of 70 atmospheres). By the early 22nd Century, this capacity had been greatly increased to 5,000 meters (500 atmospheres) for the purpose of enabling manned exploration and working presence in the oceanic abyss.



When a WAU-corrupted DUNBAT escapes from Theta without Simon Jarrett and Catherine Chun, their backup plan involves traveling to Omicron and retrieving a Power Suit, allowing Simon to safely use the climber to descend into the Abyss.

Simon acquires a Power Suit from Omicron, of which the headless body of Raleigh Herber occupies. Simon crudely rejiggers Raleigh's remains using a cortex chip, battery pack, and structure gel. This enables the Power Suit to become a cybernetic platform for a brain copy of Simon to occupy and control.

When Simon reaches Tau after traversing the Abyss, he is forced to confront [[Jin Yoshida]], who's power suit and body have been taken over and augmented by the WAU.
