Cú Chulainn, a hero from the Ulster Cycle of Irish mythology. He has been incarnated as five different, distinct characters in the Fate universe:

  • Cú Chulainn in Fate/stay night.
  • Lancer in Fate/Extra; this incarnation is nearly identical to his character in F/SN in both personality and ability.
  • Cu Chulainn (Prototype) in Fate/Prototype.
  • Caster in Fate/Grand Order.
  • Berserker Cu Chulainn (Alter) in Fate/Grand Order.

Height/Weight: 185cm ・ 70kg
Series: Fate/Grand Order
Source: Celtic Mythology
Region of Origin: Europe
Alignment: Lawful Neutral
Gender: Male
As a Caster, he does not put on any metallic equipment.

The hero of the Celtic legends of the Ulster.
He was a member of the Knights of the Red Branch and the greatest soldier of the Ulster.
It is said that, while he trained to wield a demonic spear under the tutelage of Scáthach, the master of an otherworldly realm, his mentor also taught him the magic arts of Northern Europe - runic magic.

Having manifested as a Caster, he underwent a sudden change from when manifesting as a Lancer and now torments his opponents as a user of diverse magics. Has powerful heat and flame attacks as his specialty. Apparently, the 「ansuz」 rune is being employed in this.

Rune Magic: A
Possession of the Magic Crest of Northern Europe - the runes. By making proper use of this, powerful and varied effects are mastered. However, simultaneously employing multiple effects (joint use) is inadvisable.

Wicker Man - The Cage of Scorching Flames
Rank: B
Type: Anti-Army
A giant composed by countless tree branches (wicker tree) makes his appearance. Said giant wears flames on his body and applies intense heat and flame damage by rushing on the target.

The cage on the torso of the giant that appeared as a Noble Phantasm is empty, hence the giant rages while seeking the offerings to the gods. This is not a secret art of the runes, but a Noble Phantasm of the Celtic druids, given to the Child of Light who manifested as a 「Celt magus」 that manipulates sweltering heat.

Having manifested as a Caster, he apparently has imposed upon himself the role as one who guides. Not as a true druid, but as a temporary one... So long they continue together, he shall illuminate the path that the Master walks on.
