"The ruler of ancient Britain. He is the first giant of Britain. It is said that he was born from Amphritite, the wife of Poseidon."
—Shin Megami Tensei III: Nocturne Compendium
Albion is one of the three guardians of the Amala Temple, specifically the White Temple. When the battle starts he will summon the four Zoas to his aid. Each Zoa has a specific elemental property, repelling a certain element while being being weak to another. Should all four Zoas be defeated, Albion will resurrect them, and if Albion is defeated, the Zoas will also resurrect him.
After Albion is defeated, he drops the Adama magatama and can become the Demi-fiend's minion by evolving a Gogmagog.
Shin Megami Tensei IMAGINE
Albion was first introduced during the 2014 Kappa and the Lost Utopia event. By defeating enemies in the Yodobashi Underground, players were able to spawn him alongside Tharmas, Luvah, Urizen, and Urthona. To defeat him in hard mode, players needed to balance damaging him and his Zoa minions, as defeating him while they were still alive caused him to respawn and defeating them would lead to him respawning them after a short period of time. By defeating him, players had the opportunity to acquire his plug-in and gain the ability to create him through a triple fusion of Knocker, Ubelluris, and Titan.
He and the Zoa have a unique feature called Milton, which allows them to gain 100% elemental resistance according to which Zoa are in the party. After mitama fusion, he completely nulls all physical attacks, ice, expel, death, mystic, nerve, and mind affinities. Through this and the Milton feature, it is possible to make him completely resist all damage outside of almighty.
