The Ultimate Being refers to two individual creatures that are both related to Eve and NMC. It can be considered the ultimate NMC and ultimately the pinnacle of Eve and later Neo Ark's plan.
After obtaining a gamete from Dr. Nagashima, Eve inseminates her embryo into a young patient, Mariko Anzai, who almost give birth immediately to a humanoid being. Dr Nagashima assumed that the ultimate being would be similar to Eve and would change its genetic codes by its will. Shortening millions of years of evolution into mere minutes.
Eventually because the sperm Eve obtained from Dr. Nagashima had a line of male mitochondria which will be extinct if Eve's mitochondrial strain becomes dominant, a rebellion takes place within the ultimate being's body causing it to switch between male and female.
Eventually Dr. Nagashima comforts the creature and tells that it can have as many offspring as it or she wants but she will never reproduce her father. He then embraces and hold the creature as it dies to avoid the energy unleashed from killing any more people.
The Ultimate Being, the ultimate mitochondrial life-form, grew inside the womb of the second Eve until she was defeated by Aya near the Statue of Liberty. It was created by Eve with sperm created by Dr. Hans Klamp. This sperm has no paternal mitochondria, so it cannot interfere with Eve’s mitochondria when the Ultimate Being was created.
The Ultimate Being - BabyEditWhen Eve is defeated for the final time, she becomes one with the sea of orange goop. When it first is noticed, it rocks the boat Aya Brea and her companions are on before freeing itself from the womb within the sea of orange goop with a baby-like cry. As soon as it begins to use its wings to pull itself up, nearby ships explode without even being touched. Maeda tries to give Aya something important but is forced to leave by Daniel Dollis. Aya ends up alone on the landing zone of the boat to fight the Ultimate Being in a final battle. After it climbs over the side of the boat, the Ultimate Being zones in on Aya before crawling towards her in determination and the final battle begins.
The Ultimate Being - AdultEdit
This is the final form of the Ultimate Being with its fight with Aya. As they watch from the helicopter above, Kunihiko Maeda shows Daniel what it was he was trying to give Aya before the battle began: bullets specially made with Aya's cells inside them. Daniel takes the bullets from him and jumps off the helicopter and as he falls towards them he spontaneously combusts, but throws the bullets to Aya. Aya catches them and watches in surprise as Daniel falls into the ocean. She then realizes what she must do and loads the bullets into her gun before battling again.
After the battle, the Ultimate Being begins to fall apart before landing in a lightly dazed state. As Aya turns to try and figure out what happened to Daniel, the nearly-dead Ultimate Being begins to chase after her. Running through the interior of the ship, Aya decides to turn the broiler pressure all the way to its limit to use the boat itself as a bomb. She turns on the heat and heads towards her escape as it gives chase again, just as she makes it outside and jumps off the edge of the boat it explodes with the Ultimate Being Adult still inside.
Parasite Eve IIEdit
Unlike the first, this Ultimate Being was created by Neo Ark for the purpose of facilitating their development of ANMCs. While the full extent of the plan is unknown, it is known that No. 9 intended to have the Ultimate Being's cocoon to consume Eve. The result of this is unknown but most likely, based on what happened after the fight with the Ultimate Being, they wanted to create a new Mitochondrial Eve.
Unlike the first version of the Ultimate Being, Parasite Eve II's variant is seen much earlier, stored somewhere within a massive cocoon that can be seen early on in the game. Eventually No. 9 and Kyle are seen trying to offer Eve to it, potentially to create a new Eve or a better form of the Ultimate Being. However Kyle betrays No. 9 and ends up causing him to be consumed by it. The cocoon was heavily damaged shortly thereafter by SDI firing causing the premature birth.
It can be heard crying in a similar manner to when the first Ultimate Being was born. When Aya reached the chamber below, its crying could still be heard and this quickly became distorted and monstrous as it grew into its full size. This version looks virtually identical to the baby form but also much larger and far more powerful. It is on par with its predecessor but it as destroyed, but not before grabbing Eve and transforming her into Mitochondria Eve.
