Approximately 1000 years old, he has vast knowledge of events surrounding the world, as well as remarkable foresight regarding the events and flow of causality. It is the Skull Knight who breaks into the fifth Eclipse and saves Guts and Casca from their demise. He later resurfaces during the Midland-Kushan Holy War atop the twice-reincarnated Ganishka, seemingly attempting to assassinate Femto and, with his Sword of Actuation, creating an astral tear used by the angel to trigger the World Transformation.
An ancient being, he is aloof and mysterious with a great understanding of the deterministic nature of the world. He seems to know when certain events are predestined and which are in flux. Only at temporal junction points does he actively target the God Hand, such as during the Eclipse and when Femto reveals himself atop Ganishka's Shiva form. However, despite the Skull Knight's stance as a foe of the inhumans, he has spared two apostles: specifically, the Count and Rosine, after they slaughtered the Hawks traveling with Rickert.
The Skull Knight has a long-spanning rivalry with Nosferatu Zodd, who is always excited to fight the Knight, calling him his "old friend". The Skull Knight is normally indifferent to Zodd, only showing irritation at the apostle's efforts to stand in his way when trying to save or protect Guts and his company, though the Skull Knight acknowledges their history and rivalry. He has also known and apparently had a close relationship with the witch Flora for at least several hundred years.
In spite of his coldness and deathly appearance, the Skull Knight is quite heroic, having saved Guts and Casca from the Eclipse, as well as Luca from falling to death and from the Egg-Shaped Apostle in Albion. Though he is a force for good, the Knight possesses a hopeless outlook on life, having even stated Guts and Casca's corrupted demon child would only bring them grief if allowed to live. He is, however, very insightful, having informed Guts that Casca's ultimate desire might differ from the Black Swordsman's.
The Skull Knight values the human will to survive and defy fate, even encouraging Guts to contend against causality and aptly naming him "struggler".
The Skull Knight's past is shrouded in mystery. He harbors a particular grudge against Void of the God Hand. Additionally, Slan refers to him as "Your Majesty" when he attacks in Qliphoth. He has also confirmed himself to be a former owner of the Berserker Armor, with the armor having even possessed a skull shape prior to Guts acquiring it; additionally, according to Schierke, the previous owner of the Berserker Armor fought until it bled them of every last drop of blood. He also has a history with several ancient characters, such as Zodd the Immortal and Flora, the latter whom he considers dear.
Golden Age ArcEdit
On the night of Guts' departure from the Band of the Hawk, the Skull Knight approaches him for the first time to leave him with a prophecy. While nearing Guts' campfire, his aura alone throws Guts off kilter initially, resulting in the former Hawk becoming anxious and uneasy. He begins to speak of a perilous event, coined "the Eclipse", that will take place in a year's time stating that Guts and his companions will be swept away in a torrent of madness and death. Further cautioning the "struggler", the Skull Knight tells Guts to fight and survive in spite of his impending doom before leaving the campsite and vanishing into the night.
As the Eclipse nears a year later, the Skull Knight re-surges to aid Rickert when his party of Hawks are ambushed by the Count and Rosine, among other apostles. Just as the Count prepares to engulf Rickert, the Skull Knight intervenes and demands that the apostles cease their slaughter. Surely enough, the threatened apostles withdraw from the scene, and with their departure the Skull Knight, too, retreats into the night.
On the day of the Eclipse, the Skull Knight encounters his old-time rival Nosferatu Zodd, who he presumes is guarding dimensional gate to the Interstice where the Eclipse is taking place. However, Zodd's true purpose for being there is to engage in combat with the Skull Knight. Accepting that his encounter with Zodd was within the current of causality, the Skull Knight engages in combat with Zodd, handily besting his rival and then breaking into the nearby temporal junction point.
Upon entering the Eclipse, the Skull Knight immediately attacks Void, who diverts the attack back at his assailant via a dimensional portal. After blocking his own strike and having a short stare down with his archenemy, the Skull Knight sets his sights on rescuing Guts and Casca, quickly dispatching the apostles in his wake. In his approach, however, he is targeted by Femto, who uses his newfound abilities to form a compaction ball of demons around the former. Completely undeterred by the angel's attack, the Skull Knight acquires Guts and Casca and leaves the temporary interstice.
After exiting the Eclipse and returning to the physical world, the Skull Knight orders Rickert to tend to Guts and Casca's wounds. A blood-lusted Zodd returns to resume their battle, but the Skull Knight asks that he delay their confrontation. Seeing that Guts in fact survived the Eclipse and proved his prediction wrong, Zodd leaves the scene rather intrigued by the turn of events. With Guts and Casca's wounds seen to, the Skull Knight takes Rickert and the branded survivors to a nearby elven safe haven.
Four days later, in a moonlit valley near Godo's cottage, the Skull Knight appears before Guts and informs the swordsman that, as one branded, he now resides in the Interstice and will be preyed upon incessantly by demonkind and evil spirits alike. He continues on with his monologue as specters of the night begin prowling Guts, but after being silenced by Guts for his mentions of "destiny" and "sacrifices", and witnessing the struggler's declaration of war against demonkind, the Skull Knight begins to understand how Guts survived the Eclipse. When the spirits finally cease their assault, the Knight informs Guts that the specters haven't been defeated, but have merely found another "torch" in the Interstice to prey upon, alluding to Casca's endangerment. After he and Guts arrive to Casca's location, the Skull Knight observes that the spirits are merely surrounding her, as she gives birth to a creature he comes to realize is Guts' tainted child. As the sun rises and the child fades into the astral realm, the Knight advises Guts to follow the guidance of his brand and heed the darkness he will inevitably confront, so as to not be enveloped by it, afterwards bidding the struggler good luck and taking his leave.
In the scorched land that was once the Misty Valley, the Skull Knight treads through the decimated vale, realizing that Guts had some part in the destruction. Realizing Guts hadn't fallen to evil, the Skull Knight begins to wonder just how long the swordsman will be able to continue on his path of carnage. Upon arriving at Rosine's tree, he dismounts his horse and reaches into a small gap between the tree's roots, extracting Rosine's behelit and subsequently ingesting it.
At a later point, the Skull Knight appears to Guts and explains the significance of the Tower of Conviction in the God Hand's design, as the entire area is a haven for the restless dead ripe for being the stage of an Incarnation Ceremony, where Femto will regain his corporeal form as Griffith. He states the Incarnation Ceremony cannot be stopped, as it has been preordained by fate. Guts becomes skeptical of causality's supposed ultimate nature, however, pointing out how both the Skull Knight and Zodd predicted his own death during the Eclipse, yet he still survived. The Skull Knight, impressed by Guts' resolve, reasons that the Incarnation Ceremony could differ from the Eclipse and that Guts might indeed be a "jumping fish" in the river that is causality. Just before leaving, he leaves Guts with a parting message: "Fight, or rescue. Your lover will be left alone. It won't be as simple as catching two birds."
In the nick of time, just as the Tower of Conviction partially collapses, the Skull Knight saves Luca from falling to her death and takes her to the Tower of Conviction's burial grounds. There, after encountering the Egg-Shaped Apostle, the Skull Knight proceeds to strike the apostle down; his attack misses, however, causing him to temporarily question the confidence of his sword, though he soon concludes it simply wasn't the apostle's time to die. Not long after the encounter, the two witness the large-scale manifestation of the malice pervading Albion. Realizing that the malice was taking form without the occurrence of a temporal junction, the Skull Knight comes then realizes the Incarnation Ceremony had begun.
Having distanced themselves from the commencing ceremony, the Skull Knight cautions Luca not to return to the tower if she cares for her well-being, though she returns regardless. As Luca leaves, the Skull Knight muses over her "ignorant fool-hardiness", somewhat perplexed by her calm perspective of the situation, unmoved state of mind, and her not soliciting his assistance. Despite this, he notes that he would be unable to aid her regardless, stating that, "All moves as if parallel to that time..." Shortly after, he is again approached by Zodd, an encounter indeed parallel to their previous one outside of the Eclipse. At daybreak, the Skull Knight reappears atop a penetrated tower wall in the midst of battle, motioning the combatants to look in the direction of a reconstituted Griffith.
Long after all parties have left the city, the Skull Knight looks down at the ruins of Albion atop a cliff, contemplating the events to come in wake of the White Hawk's return.
Falcon of the Millennium Empire ArcEdit
Hinted to have been the one who told Flora Guts and his group would visit her, the Skull Knight appears to witch after Guts' group leaves the Mansion of the Spirit Tree for Enoch Village. When Flora presumes that he has a favor to ask, he replies that, "Even if I don't do it myself... that one may also be a factor guided by the law of causality..." He later comes to Guts' aid in Qliphoth just as the swordsman is overpowered by Slan, disappointed to see only her and not the other angels of the God Hand. When Guts finally musters the strength to damage Slan with his Cannon Arm, the Skull Knight reassures him that his Dragonslayer – "tempered by the malice of hundreds... thousands of dead" – will be able to run through the angel. Heeding the Skull Knight's advice, Guts pierces Slan in her abdomen, resulting in the decomposition of her assumed form. Slan's abrupt disappearance has adverse effects on Qliphoth, however, as the heart of the interstice becomes chaotic and the den begins to collapse. This forces the Skull Knight to reveal his Sword of Actuation, which he then uses to seal the multiplying swarm of felled beasts into the Abyss and return Guts to safety.
Later, back in the Mansion of the Spirit Tree, the Skull Knight oversees Flora's finishing touches to the Berserker Armor, stating she must be aware of the danger it poses and its karmic nature. She concedes to his first point, but states that it will be necessary in its intended user's journey, and that the choices she and the Skull Knight have made are not predestined to repeat. Suddenly, both are alerted by the abrupt invasion of apostles in the domain. They step out onto the mansion balcony, from which the Skull Knight leaps, landing on his horse. A surprised Flora asks if he intends to defend her from the intruders, which he confirms, stating her death will be easier if not at the hands of enemies.
Not too long thereafter, Grunbeld and Zodd arrive on the mansion grounds in search of Flora. While Grundbeld opposes Guts, Zodd opts to hold off his rival, commanding the lower-ranking apostles to bring him Flora's head. the Skull Knight finds it odd that Zodd would give chase to a woman, to which Zodd retorts he simply is the only one capable of holding the former off. The Knight then comes to the conclusion that both have different reasons for opposing each other this time. In the midst of their battle, Zodd witnesses Guts donning the Berserker Armor, reminiscing over previous battles between the him and his rival and concluding that the Skull Knight must want Guts to follow in the Knight's path.
On a moonlit beach sometime later, the Skull Knight appears before Guts, warning of the harm that befalls users of the Berserker Armor and revealing that he was a previous owner of it. He cautions Guts to never make light of the armor if he wants to continue on as a human. With the advice received, a curious Guts then inquires of the Knight the reason behind the apostles' attack on Flora's mansion. The Skull Knight reveals that Griffith likely considered Flora an obstacle in his quest for worldly omnipresence, due to her magical abilities; that only those existing outside the confines of the physical realm can confront the Hawk of Light. Before departing into the night, the Skull Knight informs Guts of Sovereign Hanafubuku of Elfhelm, suggesting the elf may be capable of restoring a regressed Casca to her former self, but warns that what Casca desires might differ from what the swordsman does.
At the height of Griffith's defense of Vritannis, as he reverts to Femto and nears Ganishka, the Skull Knight appears and attempts to strike the angel down from behind with his Sword of Actuation. However, his arrival is anticipated and sword stroke manipulated by Femto via space distortion, who then redirects it at Ganshika. This triggers a chain reaction with Ganishka's Shiva form that results in the World Transformation, giving birth to Fantasia – the entire world now a global Interstice with astral creatures fully manifested in the physical world.
The Skull Knight is undoubtedly one of the most powerful known beings in the series, whose abilities allow him to oppose apostles and God Hand members alike. In all of his most recent encounters with Nosferatu Zodd, he has sustained no damage, and even bested the apostle during the Eclipse. Other apostles have even shown explicit fear in his presence, as seen with the Count and Rosine, and several God Hand members have had to actively defend themselves when at the mercy of his attacks.
As his most attributable skill, the Skull Knight's swordsmanship is masterful, allowing him to easily dispatch apostles with merely a single strike from his Sword of Thorns. Relying only on his base swordsmanship and wits, he is able to sever the arm of Zodd the Immortal in combat.
Upon swallowing his Sword of Thorns and coating it in ingested behelits to create his Sword of Actuation, the capabilities of his swordsmanship increase tenfold. One stroke of his Sword of Actuation alone operates on a dimensional scale, as seen in Qliphoth; during the collapse of the domain he is able to use his newly formed sword to not only send a horde of demonkind into an abyssal vortex, but also slice open space-time portals for near instant travel. On the head of Ganishka's god form, a stroke from the Skull Knight's Sword of Actuation, intended for Femto, is manipulated by the angel and redirected at the dying apostle – its large-scale, space-cleaving properties ultimately sparking the World Transformation.
Almost always atop his horse companion, all of the Skull Knight's most recent battles have been fought on horseback. His horse is both fast and agile, capable of swift, precise movements, leaping great distances and even running up and down vertical surfaces. While saving Guts and Casca and concurrently being attacked by a newly born Femto, the Skull Knight has no trouble acquiring the two Hawks, thwarting Femto's efforts, and escaping the temporal junction unscathed.
Most peculiar in the Skull Knight's repertoire of abilities is his foresight; he possesses strong causal awareness – knowledge of that which has yet to occur.
