Class: Saber
True Name: Hagen
Origin: Nibelungenlied
Height/Weight: 195cm / 77kg

Alignment: Neutral Good

Personality: He is a hero. To many he was the greatest possible hero, and one destined for greatness. But he was a man who was tasked with a mission, and that mission turned him into the villain. The actions he took in life blackened his name, and turned him into the slayer of heroes. As a Saber class servant, he carries the guilt of his actions heavy in his heart. Shamed of what he did, and hopeful to make amends. He is not yet the twisted and heartless killer of heroes, but a man who made a poor choice. It is a wonder what he will be like in later times.
Backstory: Due to Siegfried's nature as someone who did as he asked without question, he was involved in the dilemma between his brother-in-law, King Gunthur, and the woman Gunther desired, Brünnhilde. As the various circumstances came to a head, Siegfried was left with no choice but to die to stop conflict between Brünnhilde and his own wife, Kriemhild. He exclaimed to his friend Hagen, “Ah, the situation is beyond my control. Hagen, I am invincible and so have never once been wounded by you. But even so, if I don’t have you kill me…”

Hagen sought to grant Siegfried's wish, having formulated a plan to slay him after having tenaciously searched for Siegfried's weak point. Though he knew it was a cowardly act, Hagen aimed for Siegfried's back as he drank water from a stream, Siegfried himself not resisting the blow. He died as a "tragic hero who received a sneak attack due to trickery." Hagen became known as "a rare villain who had killed the hero through foul play." The situation after did not go as Siegfried planned, his wife later causing many to die in her revenge plot.

— Parameters —
STR: B| END: A| AGI: B| MAG: A| LCK: E| NP: B

— Class Skills —
- Magic Resistance A+: Cancel spells of A-Rank or below, no matter what High-Thaumaturgy it is. In practice, the Servant is untouchable to modern magi, so it would not be an exaggeration to title the Servant a 'Magus Killer'. Because of his elf bloodline, his strength in this skill sits at this high peak.
- Riding B: Most vehicles and animals can be handled with above average skill, even vehicles that did not exist in the time period one was alive in, for they are no exception. However, cannot ride the likes of Phantasmal Species such as Monstrous Beasts.

— Personal Skills —
- Battle Continuation B: Hagen was one of the last casualties of 'Fall of the Nibelungs.' As such, he was able to refuse the demands of his enemy, and only being beheaded ended his life. His not being fully human can be argued as a part of this unusual strength.
- Half-Elf B: Hagen is a half elf. As a Saber, this part of him is suppressed more than it would be as an Avenger. His power to utilize magic jumps up rapidly, to a degree where his efficiency in magic is beyond anything humans are traditionally capable of. As a Saber, he is more in line with that of a light elf, so the magic he constructs his more pure in nature. More for healing and protecting than for cursing and killing.
- Proof of Friendship A: A Skill to suppress an enemy Servant's fighting spirit to a certain extent, where then a dialogue can begin. However, the enemy Servant must not possess a Mental Pollution Skill. In regard to a Holy Grail War, an advantageous check can be obtained when constructing temporary alliances. This is a skill fit for a man who before his murder of Siegfried, was loved by many, and had many friendships. Something he cast aside when he became a murderer.

— Armaments —
The blade he wields is nothing short of a monstrous weapon, that even heroes look down upon. Dainsleif. The blade that brings the man who wields it to ruin and suffering.
Using Light Conversion, Hagen is able to convert his magical energy into light energy. His main method is to create flashes of light, or to heal those around him. It can be forged into his weapons temporarily, allowing him to strike with bursts of energy.
