Fushi

Fushi (フシ, Fushi), or Immo in Kodansha's simulpub version, is an immortal being created by The Beholder and placed on Earth to preserve the world.

His name can be written with the kanji 不死 literally meaning No Death/Undying. March, his mother figure, gave him this name. It was called "the Orb" in its original form.

Background
Fushi was dropped onto Earth by The Beholder as a sphere, created to help preserve the world.

Appearance
Fushi is an immortal being that can take the form of anything that has provided him sufficient stimuli.

Upon being cast onto the Earth, his original form was a featureless white sphere. Without consciousness, Fushi copied the first thing he came into contact with, which happened to be a rock. Soon afterward, he became moss and remained as such for some time. When a wounded wolf wandered close in the middle of winter and died, the immortal copied the wolf. He retains the ability to turn into these things.

Later, after the death of The Nameless Boy, he mimicked the boy's appearance and took the form of a young boy with white hair, pale complexion, and green eyes. He wears a short, brown fur cloak and a light blue shirt and pants with fur boots. A rope dangled from his hand and neck as The Nameless Boy died holding Joaan's leash, though the latter soon disappeared. The injury that took The Boy's life is also present on Fushi's left leg. Fushi commented that this form felt like it belonged to him the most.

Other than The Nameless Boy whose form he usually defaults to, he can also take the form of many others; most notably: March, a little girl with long black hair wearing a simple white dress, Gugu, a young man with defined muscles who hid his deformed face behind a salamander mask, and Parona, a beautiful young woman with black hair and a slender body.

Personality
Fushi appears to be a good listener, is curious, brave, and a fast learner. Before learning how to speak, Fushi would learn how to do things by mimicking other people's actions.

After learning how to express himself via words, Fushi speaks his mind - no matter how mean it may sound. He cares deeply for others and dislikes death. He also blames himself for the Nokkers' attacks, believing that destruction follows wherever he goes. Fushi finds it extremely hard to make friends because he knows he will have to see their lives to the end; they will always die while he lives forever.

During different stages of his life, He either becomes more human or a higher being. This is especially demonstrated in chapter 85 where Fushi has spread roots all over an old ship that Bon gave to him as a means to train his power to "make something his own", i.e., his ability to control areas and to replicate things like buildings instead of just specific objects inside it. When Kahaku and Bon visit him to see how he is progressing, they are welcomed by Fushi, who creates a table with food and drinks for them. While eating, Fushi looks mildly concerned for a moment. When asked by Kahaku what's the matter, Fushi says that a Nokker touched a part of him/his territory. Bon and Kahaku are alarmed, but Fushi stays calm as he remarks that he has already killed it. Bon notes this as Fushi distancing himself from humanhood because he seems to be no longer afraid of the Nokkers who had previously caused him immense trouble.

On the other hand, Fushi became more and more human during his time in Takunaha, where he learned to speak fluently, do chores and act (more or less) appropriately around other humans. According to The Beholder, Fushi would be equivalent to a human approximately 14 years of age.

Despite being a good listener and curious, Fushi also has a bad habit, lacks awareness, and seems apathetic, especially about social things, love, and technology. In the New World Arc, Fushi is lightly mocking another person, i.e., Tonari's new outfit, and talking about how "anti-social" Satoru is.

Abilities
As an immortal, Fushi will recover from any injury he receives, no matter how gruesome. His revival speed becomes faster with every death, from five days to six hours to minutes before he revives from death. He also resurrects more quickly as his body adapts to whatever kills him.
 * Immortality

Fushi can take shape and abilities of anything that gave him stimuli. The stronger the stimuli, whether physical or emotional, the better he can shift into said form. However, he can only shift into a living being after said living being is dead. Also, he cannot shift into someone he has never seen alive. When he tries to mimic a corpse, he will simply become a corpse and nothing more.
 * Shapeshifting

When Fushi acquired a body, the last state of the body is like a wound that the person had before their death automatically copied if Fushi witnessed the death. March's form has a bloodstain on the abdomen, and The Nameless Boy's leg has a wound, and whenever he shifted into The Boy's body, he would feel hungry, hinting at The Boy's cause of death being starvation.

When shifting into another living being, he can assume the ability of the body he borrowed. Sometimes, Fushi's personality and habits depend on the vessel he uses. Fushi's voice is also depend on the vessel it uses. Fushi has its original appearance, for example, yellow eyes. No matter what living form that it uses, it showed yellow eyes.

Fushi only can transform into everyone that he has ever seen. So no matter how old that person he knows died, if he is not with that person, he never knows the state and the growth of the body. So, he only knows the shape and age of the body when the last time he saw them. For example, Parona, Rean, and Shin. Also, when Tonari and Bon died old after the Renril arc, Fushi was not with them, so Fushi only can transform into their body in the condition when the last time he saw them, or the growth he knows.


 * Intelligence & Environmental Adaption

Fushi learns very quickly and is constantly observing the things around him.


 * Empathy

Fushi has the psionic/extrasensory ability to sense bodily pain in others, even if he cannot see them. He was also capable of sensing Gugu and Rean's feelings of love. This allowed him to gain emotional stimulation from living beings around him and enabled him to shift into their form. As of now, he can also sense spirits due to Bon.

When it comes to non-living things, Fushi only needs to receive the stimuli from them once before recreating the objects perfectly for an unlimited amount of time. The greater the stimulus, the deeper it is imprinted in Fushi's memory. The greater the stimulus was, the easier for Fushi to replicate it. Yet, depending on his future growth, the day may come when Fushi is able to replicate even the smallest stimuli. It's the reason why he would often rub food, books and other objects to his arm, though he prefers to buy things after he experienced them to take part in the economy.
 * Replication

When asked by Gugu what else could he do, Fushi was able to replicate the spear made by Parona. So far, he can create corpses of the people he's seen, the shell of a crab, various books, various weapons (including explosive arrows), unlimited money, a doll, and many kinds of food which seemed to be perfectly safe to be eaten by humans.

Later, after being caught by the Church under the accusation of heresy and imprisoned in an iron box and had molten iron poured in, Fushi gained the ability to replicate the molten iron's heat and used it to escaped from his prison after a few days.


 * Resurrection

Using resurrection, Fushi can create a new body for the dead and allowing their "fye" ("essence", "soul" or "spirit) to return to the living realm. However, he cannot revive the people he has never seen alive as he cannot grasp how the person was before their death. But, when he using Bon's body, he can revive everyone who stays in the world as a spirit, because his body can see them, although Fushi never met them. i.e., Fen and Nixon.

Fushi can only revive every living being whose soul or Fye remains in the world. Fushi can't revive every living being if the soul or Fye in paradise.

After being bathed in molten iron, Fushi acquired regenerative powers which allows him to endure extreme
 * Self-Regeneration


 * Heat Generation

The molten bath of Iron also gave him the ability to generate heat, strong enough to melt iron.


 * Willpower

During this hell in the molten iron, he also gained the ability to transmit a strong will across his whole body, which willed him to escape. This will power seems to have increased his endurance, and allowed him to make his flesh like unto iron or harder.

Fushi can replicate several parts, and create his territory from all separated objects, and if Nokkers come to attack in his territory, no matter how far, as long as still in his area, Fushi can easily create his weapons, something like swords, dead trees, to attack. He can also further extend his consciousness via roots and make it his territory.
 * Territory Domination


 * Transferring Consciousness

The first time he creates his form and becomes able to share his consciousness, and it took about 5 seconds to transfer. As long as he connected to his territory, he can return to his main body.

Fushi has the power to reconnect to whatever has been severed.
 * Reconnection

Quotes

 * "A friend to me is someone who remains beyond death." (Chapter 61)
