Great Beast Albion「アルビオン, Arubion」 are giant golems created by the Demon Clan during the ancient war between the allied clans. They were reawakened after the seal on the Coffin of Eternal Darkness was broken.
Albion are gigantic creatures the size of mountains. They appear to be formed from the earth by demonic magic and as a result, possess the black marks that are typical of the Demon Clan.

The Albion were created 3,000 years ago by the Demon Clan as weapons to combat the allied clans.
When the Ten Commandments are revived, they release two Albions in Britannia.
One of them attacks the kingdom of Camelot.

It shoots to a flame to the barrier, however, the Holy Knights succeed to neutralize the Albion's attack, but he is not sure that they will survive the second attack. As Arthur feared, the Albion shoots another flame. The Holy Knights desperately try to shield their king with their bodies, but the Albion attack is reflected by Meliodas' Full Counter. Following Meliodas, Arthur ordered the Holy Knights to climbed the Albion's arm. Arthur got trapped under Albion's hand, but Meliodas saves him quickly, breaking Liz's Sword in the end. After Meliodas gets his Sacred Treasure, Lostvayne, back from Merlin, he slices Albion's left arm easily in one move and finally defeats the Albion using his special technique Jitsuzō Bunshin.
The Other Albion attacks the Fairy King's Forest. When the fairies run scared, the Albion is confronted by King. However, none of the forms of Chastiefol is strong enough to hurt the Albion, who injuries King and slices the Sacred Tree. In the end, King releases the true form of Chastiefol and destroys the Albion with one hit.

When Diane uses her Queen Embrace to ambush them, one of them manages to deliver a direct hit but Diane is unharmed grants to Heavy Metal and ends the Albion with one hit from Gideon. Finally, King uses Chastiefol's Tyrant Tempest to eliminate all the Albions. The rest of the Albions are destroyed by Sariel and Tarmiel's Omega Ark.
