Percival

is one of the Four Knights of the Apocalypse, and named a Holy Knight of Kingdom of Liones with his companion's as the Percival Platoon. His Magical Power is the extremely rare Hero-type, Hope. He is the main protagonist of the eponymous series.

After prevailing against Mortlach, Percival believed he was doomed to bring his companions to their end and chose to abandon his human vessel, thus returning to his existence as a Life Spirit and ending the life of his human form.

Appearance
Percival looks like a very young boy showing a small and lean figure, despite being in his late adolescence, with green hair and purple eyes. His outfit composes of tunic cloth and short. He later wears his grandfather's purple horned iron helmet and an orange cloak with a brooch shaped like a serpentine creature biting his own tail.

After an encounter with Ironside, Percival harbors a very large cross-shaped scar on his upper body, tilted slightly to the right. The same scar also extends to his right arm, which aligns perfectly with the scars on his body when standing with arms down; the position of his body when he received the scar. In the anime, the scar is larger, and travel all the way around his body and left arm to the back.

Personality
Despite being a teenager, Percival acts like a very young boy with extreme innocence and naivety and is easily mistaken for a young child due to his short stature and attitude, surprising him that people see him as such.

Because he has grown up in an isolated environment, away from the outside world and humanity, with his grandfather as the only acquaintance, he overflows with curiosity towards everything he does not know, and since there is much that he does not know, he is always excited with the prospect of new experiences and aventure.

Due to his lack of experiences in life, he is extremely naive, easily relying on people he barely knows, to hand over all his belongings, or to follow them where they went.

Having lost his grandfather, whom he loved more than anyone else, Percival leaves his home, in large part to find his murderer, but also because he wants to go on adventures just as his grandfather inspired him to do so.

Appreciating the words of his grandfather, Percival tries to act as a Holy Knight should, facing the evil and protecting the weak.

He seems to be quite interested in women, observing Elva's body (and pawing her breasts) when they were bathing in the lake, but instead as a genuine curiousity rather than lustful intent.

History
Percival was born sixteen years ago, during the year of the New Holy War.

According to Ironside, he found Percival, the seventh prince of an unspecified Kingdom, in a wagon that fell off a cliff. Taking him back to Kingdom of Camelot, he intended on using the deceased child as the vessel of a powerful Life Spirit using a forbidden spell which cost some of his life-force, with the intention of transferring the soul of his son into him, so that he could have an immortal body which would allow him to live outside of Camelot and live on for millennia.

That same night, Varghese betrayed Camelot and King Arthur Pendragon, due a combination of his change in personality due to Chaos' power and Ironside's intentions for Percival. Hoping to one day change Arthur back to his old self and stop the Holy Knights of Camelot who blindly followed their king without question; all while being hunted by his former colleagues until he finally made his way to Camelot's enemy, due to their conflicting ideologies about to co-existence of the five races: the Kingdom of Liones.

There, he was met by the new king, Meliodas, who had the injured knight treated as where Varghese explained his reasoning for betraying Camelot, which Meliodas believed in. He then bestowed upon his an ouroborus medallion as a token of eternal friendship and carved two stars onto his helmet as a token of trust and cooperation. Despite this, seeing as Varghese was now a fugitive of Camelot and with nowhere to go, Meliodas gave the offer to raise Percival for him but Varghese was insistent that Percival would be his responsiblity and would raise him to be the kindest boy he could be in opposition to his cruel son's blind loyalty to King Arthur.

After this, he traveled with Percival to God's Finger, where he raised him in total isolation until the beginning of the series, teaching him to fight since he was only three through Gouren.

At some point when Percival was no more than a year old, he ended lost in the Demon Realm by accidentaly crossing an entrance in a cave of God's Finger. There he was adopted by the current Demon King, Zeldris, who cared for him alongside Gelda until they were finally able to return him to his world. During this time, the demons came to worship Percival for he saved the race from Behemoth, healing the demons whose life force had been taken and restoring the beast to its sleep, considering him their "savior". It is around this time in the Demon Realm that Percival learned the Demon's language.

Due to being raise by Varghese and surrounded by his love, Percival forgot that he was a Life Spirit and gained self-awareness.

Percival arc
Percival is first seen chasing a Roc Bird while being assisted by his grandfather, Varghese, while the two live in isolation on top of God's Finger. After eating the creature, the two take part in a match of Gouren in which Percival loses and vents on his loss but his grandfather reassures him of his strength.

The old man suddenly remembers that tomorrow is Percival's sixteenth birthday and explains how turning 16 is the entrance to adulthood and how he will soon set off on his own personal journey. However, Percival expresses no interest and claims that being with his grandfather is enough, much to the latter's shock. Later that night, Percival sneaks outside and remembers his grandfather's words and reveals he does in fact wish to seek these thrills but after waking up the next morning, finds a strange knight in red armor approach the summit on a flying boat.

The boy is shocked and amazed at how one of his grandfather's tales are true while the knight asks if Varghese is around. After directing the knight in the direction of the house, Percival gets an ominous feeling and returns to the house to find the red knight attacking and mortally wounding Varghese. Percival attempts to attack but the knight easily overpowers him and attempts to silence the boy by using his power to give him a star-shaped cut through his body and further attacking Varghese, leaving the two to die in the snow.

Percival, despite his wounds, comes to his dying grandfather's side who explains that the red knight's name is Ironside and that he is his son, thus making him Percival's father. The boy is confused as first due to Varghese having told Percival that his father died when he was very young and his grandfather apologizes as he had to lie for reasons unknown. Before dying, he tells Percival that if he wants to understand why, he must seek out his father and ask him.

Some time later, Percival sits in front of Varghese's makeshift grave while the man's helmet and cape left to the side. He remembers his grandfather's last words and resolves to set out in search of his father to find out why he attacked them.

After two days of descending the height of God's Finger, Percival reaches the land of Britannia, and is encountered with a mysterious talking fox-like creature, Sin.

Abilities and Equipment
As a powerful Life Spirit in a Human vessel who gained self-awareness, Percival's small stature bellies incredible strength and abilities beyond average fighters. It is first shown when he takes out a house-sized monstrous wolf with nothing more than a slap to the face, sending it straight into the ground and cracking the earth. Percival has a unique constitution, affording enough resilience to stand upright showing little-to-no pain despite being hit by Ironside's magical power, leaving a massive scar on him, whereas Varghese, a former Holy Knight was viciously mutilated and blinded. As an infant, after falling into the Demon Realm, Percival survived its harsh conditions and breathed normally, unaffected by the miasma. He has a unique resistant against drugs and sleeping chemicals; waking up shortly after being given Belladonna leaves that were intended to knock him out for ten hours.

Having liked on God's Finger with his grandfather, Percival learned a great deal of hunting and cooking skills from him, making use of a sword to properly and efficiently skin a Roc Bird, and then filleted fish. Despite this, however, Percival's dismal archery skills borders on being implausible, having the apparent ability to hit the targets behind him, despite the fact that he was aiming at the targets in front of him. Percival's breathing ability is much greater than other Humans, running around with ease on God's Finger, despite normally being difficult to breath in such a location, withstanding Chion's Sylph which blocked air around him.

As one of the Four Knights of the Apocalypse, Percival is an extremely talented Holy Knight, managing to awaken his magic power in the middle of a difficult fight; using it to reverse his situation and managing to gain the upper-hand against his opponent, albeit, he wasn't fighting seriously.

His fighting skills seemed to be basic, to the point of barely holding his own against more experienced Holy Knights, such as Pellegarde without aid, who weren't taking him serious. It wasn't until Lancelot's training, emulating the people he couldn't defeat: Talisker, Macduff, Pellegarde, and Ironside. Although, Zarura N'Du passed the second and third level, Percival managed to defeat the fourth level and then training with Lancelot; improving his sword skill, to the point of countering and wounding Mortlach's "Thousand Cross", whose sword skill is described as superior to Ironside.

Abilities

 * Percival's Power manifested during his fight against Pellegarde. He is able to tap into the hope of his allies, allowing him to generate a magical aura around his body, or part of it. This aura can be used in several different ways. Pellegarde speculates, due to its multiple uses, that it could be a "Hero Type" magic that only appears in one from among all people. This power seems to come from the ability of Life Spirits to spread life through hope.
 * Enhanced Healing: Covering his body, Percival can heal injuries such as severe burns in a matter of seconds.
 * Resurrection: Attacks that would normally kill him would have him regenerate from fatal wounds such as surviving after having his neck snapped by Macduff. However, it seems he is only able to use that power to revive himself and not others who are dead shown when he failed to bring Jade back to life.
 * Enhanced Strength: Covering his fists, Percival's physical strength increases considerably.
 * Form Taking: The aura can take form of anything Percival imagine. Like a hand to hit his enemy, or a mouth capable of absorbing magic attacks and throwing them back.
 * Magic Golem Creation: Takes the form of minimized clones of Percival. Is unclear how much control he has over these clones, but they seem capable of simple acts such as swarming Percival's enemy, they are able to maintain conversations among them, and they seem to have a certain level of independence. They seem to have considerable physical strength. The golems are also able to heal injuries, track down things and explode causing considerable damage.
 * Absorption: The magical golems are able to take in attacks aimed at Percival and hold them inside themselves before expelling the attack back in the direction of Percival's opponent.
 * Flight: Covering his body, Percival can form wings and levitate in the air through his aura. When in a berserk state, he is seen flying unsupported without Hope.
 * Mummification: A mysterious ability Percival's first used on Chion when he believed that all his friends were dead. By merely touching living beings they are turned into a state of mummification. This state seemingly cannot be reversed by anyone except for Percival himself through Hope. It seems to derive from the ability of Life Spirits to spread death trough despair.
 * Demonic Language: After spending part of his early childhood in the Demon Realm, Percival is said to have learned the "secret language" of Demons from Zeldris and Gelda, which notably allows him to communicate with Lesser Demons such as those of the Dalfare Range or to command directly at the Albions.
 * Percival, together with Donny, Nasiens and Anghalhad, use their swords in a joint attack against an opponent.

Weapons

 * Ouroboros: A magic sword that can change its size, inherited from his grandfather, which Sin described as a first-rate sword. But, instead of using it as an actual weapon, Percival uses it as a carving knife.
 * Dragon Handle: A fragment of the Coffin of Eternal Darkness. As the handle seemed "too heavy" for Percival, Howzer made sure to "reforge" it with a "thick" blade for balance. The sword does not appear "especially magical", but is known for its sturdiness. By concentrating Hope's destructive properties into this sword, Percival is able to make it much sharper. The nickname "Percival Sword" is not very popular.

Varghese
Varghese is Percival's grandfather and was his only family. Percival greatly admired and loved him, as the two had a very good relationship and never showed any signs of anger or annoyance with him. Percival was determined to give up his dream of adventuring in Britannia to accompany his grandfather so that he would not feel alone. In short, Varghese was the special person Percival wanted to protect above all else, and even if he doesn't show it, his death affected him a lot, crying during the cold nights when remembering the warm embrace of his grandfather.

Ironside
Ironside is Percival's father, as well as the murderer of his grandfather Varghese. Although at first he was very curious about its origin and particular means of transport, Percival is very resentful with him, although it is not clear if he hates him to the point of wanting to kill him, he is determined to find him and defeat him to find out why he did what he did.

Donny
Donny was one of the first people that Percival met after leaving God’s Finger. At first, Donny takes advantage of Percival’s naive personality, stealing all of his things and running. But when Percival is able to catch up with the carriage on foot, Donny hazily allowed him to join. Eventually, as they travel together, Percival and Donny become very close friends and allies.

Lancelot
It seems as though Percival looks up to Lancelot quite a bit, originally shocked at the fact he was a “talking fox”. Once he and Lancelot travel for awhile, the two spar as a way to train Percival. Eventually, after unleashing his Life Spirit double, he is able to beat level 1-4 of Lancelot’s fighting ability. This included replicas of Pellegard and Ironside. The only version Percival cannot beat is level five, which is Lancelot himself.

Lancelot sees Percival’s potential, but feels as though he’s not living up to it yet. He believes that Percival doesn’t know how to control his own power, and wants to help get him to the place he needs to be in order to defeat Chaos Arthur.

Nasiens
Nasiens originally thinks very little of Percival, and being skeptic of most people, assumes that he’s trying to lie to him. When it turns out that Percival was telling the truth, and willingly risks his life for the gorge, which has no meaning t him, Nasiens warms up. He admires Percival, and after Percival continuously helps him, he gains romantic feelings for him as well. Percival’s feelings for Nasiens are also unknown but it is implied that he relates to Nasiens, and pities him for the loss of his grandfather. Percival is shown several times to especially empathize with those with close relationships with their grandfathers after Ironside killed his own.

Anghalhad
Anghalhad seems to have romantic feelings for Percival, though she denies them. Percival’s romantic feelings towards Anghalhad are unspecified as of current, but it is shown that he cares deeply for he, as when she gets injured, he rushes to her side to check on her.
