Excalibur

Archer Yoshimoto, known as Excalibur professionally, is a student at the ZPA and descendant of the Japanese villain Shinigami. He is fairly muscular and has choppy black hair. He cannot speak Japanese except for short phrases.

History
Archer was born to a Cornish mother, Tamsyn Penrose and Japanese father, Akihiro Yoshimoto in Portland, Oregon in 1977. Unbeknownst to him until four months ago, he is a descendant of Eiji Yoshimoto, better known as Shinigami, Japan's worst villain in history. He was slain by Archer's father, Akihiro with the very power Eiji gave him: Summoning... Only for him to mysteriously come back to life and exact his revenge on the Yoshimoto family.

Archer barely escaped with his life from the encounter with his grandfather and was scarred for life. The Vanguard heard of this incident and took him in for protection. In exchange, he volunteered to join the students at the ZPA while The Vanguard tracked down his grandfather.

Pre-Season 2
In early February 1998, Archer tracked down his grandfather, the vile Shinigami and killed him with his own sword. He returned to school a changed man, having seen the destruction of Tokyo firsthand... Though he also knew he had to be there for his new allies, who lost someone close to them in return.

After winning the tournament, Archer decided to use the powers his grandfather gave him in war. He was sent to Afghanistan, where he became known as "ʾAlf Suyuf", The One Thousand Sword, or to his American comrades, "The Butcher of Kabul". Archer's power excelled in combat situations... Though it became too much to bear when he was ordered to attack the city of Kabul without warning. Around 10,000 civilians and soldiers alike were killed that day by Archer's volleys.

After that day, he requested to be moved somewhere else. His commander was disappointed at his request, though obliged. In 2002, he was sent to Germany as a peacekeeping officer. There, he met his future wife, Sofia Jonas, a half-English woman from Hamburg. He decided to settle down with her in Hamburg, and started a family with her.

Costume
Excalibur wears an Arvwisk Gwer, "The Green Armour" in Cornish: a suit of emerald-green armour that can never be penetrated. In turn, he can summon the famous sword Excalibur from Arthurian legend, Excalibur, from his Sword Gates. This combination is not just flashy, but extremely effective for one-on-one combat.

Power
Archer's power is known as One Thousand Gates, which can propel weaponry of his choice out of a line of portals. Usually, Archer chooses to go with longswords, if only to look cool. It has immense range and power, devastating all in its path.
