Description
Percival is the main protagonist of the anime The Seven Deadly Sins: Four Knights of the Apocalypse and one of the four knights named in a prophecy that they will bring ruin upon the world. He is a sixteen-year-old boy of small stature with bright green hair styled into two wild cowlicks that resemble wings, and after his grandfather's death he wears the old man's cowl and helmet nearly everywhere he goes. Percival grew up in a remote and isolated region known as God's Finger, a towering rock formation far from civilization, where he lived alone with his grandfather Varghese, a former Holy Knight who quietly raised him away from the outside world.

Because of this secluded upbringing, Percival developed a pure, innocent, and trusting personality. He is curious about the world, somewhat childlike in his thinking, and easily deceived by those with ill intentions, yet he is also genuinely kind to everyone he meets, including talking animals and beings that others would fear, such as demons. His grandfather raised him to have a strong sense of justice, so Percival cannot tolerate cruelty or wrongdoing, and even toward enemies such as the knight who killed his grandfather, he prefers to avoid taking lives and is willing to seek reconciliation with those who are essentially good at heart.

Percival's quiet life is shattered when the knight Ironside appears at God's Finger, kills Varghese, and reveals himself to be Percival's father. Grief-stricken and desperate for answers, Percival leaves his isolated home to find Ironside and learn the truth behind his grandfather's death, a journey that also fulfills Varghese's final wish that his grandson see the vast world beyond their home. Along the way, he discovers that he is one of the Four Knights of the Apocalypse, the knight who represents Death, and that the prophecy ties him to the eventual destruction of King Arthur's Camelot. His personal quest for vengeance gradually transforms into a larger mission as he embraces his identity and the responsibility placed upon him.

Later in the story, a deeper truth about Percival's origins is revealed. He is not actually Ironside's biological son. Instead, he is a Spirit of Life, a magical entity sealed by forbidden magic into the body of Diodora, Ironside's deceased son, as part of a plan by the knight to give his heir an immortal body, a scheme that ultimately went out of control. This revelation shapes Percival's understanding of himself and his place in the conflict between the four knights and Camelot.

In the story, Percival takes on the role of the central hero who gathers companions and grows into a leader. He forms the Percival Platoon with the traveling companions he meets early in his journey: Donny, Nasiens, and Anne. These three become the emotional core of his life, and their faith in him is directly tied to the power of his magic. The mysterious red fox named Sin, who accompanies the group, is later revealed to be Lancelot in disguise, and he serves as both a mentor and the oldest friend Percival gains on his journey. Ironside and his grandfather Varghese represent the two opposing poles of Percival's origin, with Ironside standing as his primary antagonist and Varghese as the source of his values. The Chaos Knight Pellegarde is another recurring adversary who takes an almost paternal pride in Percival, offering a contrast to Ironside's hostility.

Percival's notable ability is his magic Hope, an extremely rare type of power known as the Hero-type. Hope allows him to convert the hopes and feelings of his allies into personal strength, manifesting as small miniature copies of himself that can take the form of swords, wings, shields, and other shapes. He can use this magic for attack, defense, healing, flight, and the creation of small golems that can assist him in various ways, such as tracking enemies or deflecting attacks. He also possesses superhuman strength, speed, endurance, and exceptional pain tolerance, along with advanced swordsmanship and archery skills taught by his grandfather and remarkable control over his breathing. As the Knight of Death, he has the ability to resurrect himself even after sustaining massive wounds, though he cannot revive others. He also displays a mysterious power that can mummify living beings simply by touching them, an ability only his own magic can reverse, and he is able to understand and speak the demon language, resists the effects of magical drugs and sleeping agents, and wields powerful magical swords, including the shape-shifting blade Ouroboros and his primary weapon, the Dragon Handle.

Over the course of the series, Percival develops from a naive and sheltered boy into a genuine hero. Through his experiences with his companions, his training under Lancelot, and his confrontations with the knights of Camelot, he learns to fight not simply for revenge but to protect those he believes in. In the later stages of the story, he reaches a point where he gives up his human existence and returns to his original state as a Spirit of Life in order to stop a great threat, a sacrifice from which his companions manage to bring him back two years later. He also comes to accept his feelings for his close friends Anghalhad and Nasiens, asking them to form a family together, and he is eventually shown as the father of children in the continuation of his story.
