Aya Brea is the is the central character and main protagonist of the Parasite Eve video game series developed by Square Enix (formally Square). The character first appears in the 1998 role-playing video game Parasite Eve. In the game, she is a rookie 25-year-old police NYPD officer whose life changes when a date at the Opera Tonight (tonight being Christmas Eve 1997) goes horribly wrong. She faces off against Eve, a being created by sentient mitochondria wishing to conquer life on earth. As the only person to not not-so-spontaneously combust upon the awakening of Mitochondria Eve, she struggles to understand and rein in her own bizarre powers while racing to stop Eve from giving birth to the ultimate being and destroying and/or forcibly evolving humanity in the process. She's immune to Eve because they share donor organs from her twin, Maya. More on that further down. In the 2000 sequel Parasite Eve II, set three years after the events of Parastie Eve as an ace operative of the FBI's anti-mitochondrial mutant task force, MIST (Mitochondrion Investigation and Suppression Team), formed following reports of Eve's mutated animal minions spreading out from Manhattan, and is investigating further activities involving mitochondria. Aya's journey to destroy the newly-monikered "Neo-Mitochondrion Creatures" (NMCs) and put a seal on her own unpredictable powers leads her to Los Angeles. However, an investigation into an NMC outbreak near the ghost town of Dryfield, Nevada hits closer to home. In the 2010 game she is the false protagonist The 3rd Birthday, an amnesiac Aya is found by the Counter Twisted Investigation (CTI) unit to fight against the "Twisted", a mitochondria-spawned creature that has taken over Manhattan. Apart from her name, she remembers nothing about herself or her past. When the CTI (Counter Twisted Investigation team) found her, she was wearing a bloody wedding gown outside the St. Thomas Cathedral in Manhattan, either just before or just after her own wedding. After taking her into custody, the CTI realized her abilities allowed her to dive into a human's past consciousness. Understanding that this was humanity's only chance against the space and time-defying Twisted, the Overdive Investigation Unit was formed to develop a way to use Aya's powers against them.

Except this isn't Aya at all. It's Eve, from Parasite Eve 2, in Aya's body, the result of a failed emergency transformation. As a result, she actually regains a mix of both her actual memories and Aya's, resulting in a huge tomato surprise.

In the first game, the player can rename her, although her default and canon name is Aya (pronounced eye-ya). As she reveals to Gary Douglas in Parasite Eve II, her name is of Japanese origins, possibly as meaning color "彩“ or one of various other meanings.

In the MIST HQ also reveals she got 2nd place in the most recent MIST shooting competition, losing out only to Rupert Broderick. Otherwise has average human level intelligence

Weaknesses: She lost some of her abilities at end of the first Parasite Eve including LIBERATE

Notable Attacks/Techniques:

  • Heal: Aya heals herself
  • Scan: Reveals enemies strengths and weaknesses
  • Slow: Slows down someones movement speed
  • Detox: Aya heals herself from poison
  • Barrier: Aya puts a barrier around herself making herself immune to attacks, but slowly drains her energy
  • Energy Shot: Channels all Aya's energy into a single bullet, which results in a devastating blast
  • Confuse: Confuses the enemies, preventing them from attacking
  • Haste: Increases Aya's movement speed
  • Gene Heal: Steadily regenerates Aya's health
  • Medic: Heal's Aya from all status effects
  • Preraise: Automatically revives Aya when she dies. This only works once, so if Aya is killed again, she will stay dead.
  • Full Recover: Fully stores Aya's health and status
  • LIBERATE: This ability liberates Aya's mitochondria, transforming her. Aya becomes a powerful blue-green mitochondrial creature with wing-like appendages sprouting from her arms. She'll deal out several powerful attacks before transforming back

Powers Regained (Parasite Eve 2):

  • Healing:
  • [Lvl 1] Increases mitochondria to enhance energy output and speed healing until the mitochondria weaken.
  • [Lvl 2] Improved Healing. Regenerates lost cells at cost of mitochondrial energy.
  • [Lvl 3] Advanced Healing. Directly converts mitochondria in the host to energy, promoting rapid healing.

  • Metabolism:
  • [Lvl 1] Uses mitochondria to form antibodies, causing a natural immunizing reaction. Not 100% reliable.
  • [Lvl 2] Improved Metabolism. Speeds up production of white blood cells to counter toxins. Effective, but still requires time.
  • [Lvl 3] Advanced Metabolism. Heightens metabolic rate to lightening speed. Instantly detects neutralizes, and eliminates toxins.

  • Lifedrain:
  • [Lvl 1] Indirectly controls mitochondria in adjacent organisms, using them to generate an electrical current to boost healing.
  • [Lvl 2] Improved Healing. Regenerates lost cells at cost of mitochondrial energy.
  • [Lvl 3] Advanced Healing. Directly converts mitochondria in the host to energy, promoting rapid healing.

  • Pyrokinesis:
  • [Lvl 1] Activates mitochondria in the hands, emitting a flash wave of heat. Targets sustain burn damage.
  • [Lvl 2] Improved Pyrokinesis. Greater accuracy. Fires two simultaneous bursts, searing target.
  • [Lvl 3] Advanced Pyrokinesis. Best accuracy. Fires multiple bursts, causing target sublimation.

  • Combustion:
  • [Lvl 1] Activates mitochondria in skin, causing combustion. Heavy burns on the target complicate cutaneous respiration.
  • [Lvl 2] Improved Combustion. Greater range of effect, Sears target's lungs, causing internal burns. May cause suffocation.
  • [Lvl 3] Advanced Combustion. Best range of effect, Combusts body fat melting target like a candle.

  • Inferno:
  • [Lvl 1] Uses radioactive isotopes to set off nuclear fission. The resulting inferno turns targets into lumps of scar tissue.

  • [Lvl 3] Advanced Inferno. Uses radioactive isotopes to set off nuclear fission. Reduces targets to piles of molecules.

  • Necrosis:

  • [Lvl 3] Advanced Necrosis. Best discharge range. Necrostizes target's osteocytes (bone cells).

  • Plasma:
  • [Lvl 1] Activates mitochondria creating a discharge that detonates air molecules. The blast wave knocks down nearby targets.
  • [Lvl 2] Improved Plasma. Generates an ion discharge, detonating air molecules. The great blast wave smashes down targets.
