King Uther Pendragon is the father of King Arthur.
yes
Yes, Uther did.
It has not been confirmed. The books have only revealed three of the possible demigods in the Great Prophecy. However, the other four are unknown.
The big hungry great white shark
Uther Pendragon, the King of England, was deeply in love with Igraine of Cornwall. Uther's assistant, Merlin, a magician, promised that they would be married if Uther gave Merlin a son. So, Uther and Igraine fell in love and had Arthur who was sent to live with Sir Ector for safety and because Uther was going to die.
Arthur was the son of Uther and Ygraine - but Ygraine was NOT Uther's wife when Arthur was conceived. Had Uther and Ygraine had other legitimately conceived children, Aurthr would have been .... "inconvenient", and a potential threat to Uther's other sons. For Arthur's own safety, Merlin took the infant Arthur away to be raised separately. One more point; there is only ONE KING AT A TIME. If Uther was King, then Arthur could not be - and Arthur could not be King while Uther lived.
King Arthur's father is King Uther Pendragon.King Arthur's biological father was Uther Pendragon. His adoptive or foster father was Sir Ector.
Merlin gave him a drug that transformed Uther into Gorlois's likeness. Uther then lied to Igraine about how he'd slipped from the seige to see she was safe
In the traditional sources; ie Morte d'Arthur & Vulgate Cycle, Uther doesn't have a "ward". At least none are mentioned. In History of the Kings of Britain by Geoffrey of Monmouth, Uther has daughter named Anna and Arthur his son. In later versions, only Arthur is mentioned as Uther's child.
