Galahad

Sā Garahaddo is one of the Knights of the Round Table.

Background
Galahad was a later addition to the Round Table, especially famed for his escapades in the search for the Holy Grail. He was a "saint who was the only one to obtain the Holy Grail, just to return it to heavens."

Appearance
Galahad's father, Lancelot, comments that Mash is wearing her hair in a similar style to him. In Tristan's Ascension art, there is an image of an unknown Knight of the Round Table with similar hair that may correspond to this comment.

Fate/Grand Order
Summoned by Chaldea, Galahad began to disappear as his master was recently killed. The fading Galahad formed a contract with the human Mashu to form the Demi-Servant Shielder. Mashu obtained his fighting experience, skills, and Noble Phantasm, but lacks even knowledge of who is fused with her until later in the story. After granting her his skills and Noble Phantasm Galahad faded away.

Other appearances
He was briefly mentioned in the original novel of Fate/Zero when Saber fought against Berserker. As Berserker revealed his true identity, Saber was tormented on how she led her kingdom. She thought of her knights and wondered if they had left this world with resentment and unwillingness. Saber claims that Galahad had lost his life in the line of duty.

Abilities
Galahad possesses the Noble Phantasm Lord Camelot.
