Bedivere's Noble Phantasm weapon is a silver arm known as "Airgetlam" ("Silver Arm"). This is a combination of two British myths:
- Bedivere in Welsh mythology was known as a one-armed knight
- the Airgetlam is an Irish treasure that was given to the Irish god Nuada who had suffered the loss of his hand.
Sir Bedivere was previously seen as a female in Subete tooki risoukyou (2006), while in this feature he is a confirmed male.
