Zero Lancer, true identity Diarmuid Ua Duibhne, is a Lancer-class Servant summoned in the fourth Holy Grail War. After battling Meta-Mind in an Honor Duel during Wave 4, he was persuaded to join The Resistance and fight at Meta's side until they could eventually have a true showdown.


Zero Lancer was originally Diarmuid Ua Duibhne, an Irish folk hero. Said to be the first warrior of the knights of Fianna, Diarmuid was known for his "Love Spot" - a small mark beneath his left eye granted by a young girl, which causes any woman who gazes upon it to fall in love with him. Eventually, this spot led to an encounter with Gráinne, the bride of Diarmuid's master Fionn mac Cumhaill. Upon seeing Diarmuid at her wedding party, Gráinne fell in love with the hero, eventually convincing him to run away with her. Though Fionn pursued the two at first, he eventually forgave them and allowed Diarmuid to return and live as his subject.

Some time later, Diarmuid was out on a hunting trip with Fionn when he was mortally injured by a wild boar's tusks. As Fionn could transform spring water into a powerful healing agent, Diarmuid had no fear of death - but with his jealousy towards Diarmuid on his mind, Fionn spilled the water twice. By the time the lord of Fianna had come back for a third trip, Diarmuid was dead.

Diarmuid would later be summoned by Kayneth Archibald El-Melloi as a Lancer-class Servant in the Fourth Holy Grail War.

His reasons for appearing within Castle Lololo, or for serving the Guard, are unknown.

After appearing in Lololo and being fought to a draw by Meta-Mind, Lancer agreed to serve as Meta-Mind's left hand, fighting beside him until the time the two can have a more decisive duel.
