A male Arthur could be explained as the Male is based on the LEGEND of King Arthur while Arturia is the true King Arthur. They did the same thing with Jack the Ripper, remember?

Only as an April Fool's joke. I'd take anything from Strange Fake with more than a pinch of salt, unless it's been shown somewhere else. XD

Rumours cannot become Servants. The entire mechanism by which a Heroic Spirit exists requires a person in the first place.

[hider=The Short Explanation]A Heroic Spirit starts off as a person, they do something REALLY amazing and legends form around them, they end up in the Throne of Heroes, the Holy Grail War uses a bit of the Third Magic to pull the Servant entirely out of the Throne for a bit and sticks them in a magical construct. No person = no Servant.[/hider]
