Morgaine

Morgaine, also known as The Sunkiller, Dominator of the Thirteen Worlds, and Battle Queen of the S'rax, was a powerful sorceress from another dimension, who did battle with King Arthur and Merlin.

Profile
Morgaine had a strong sense of honour. She became enraged when, by reading a tombstone, she discovered her son, Mordred, had mislead them and they had fought on the enemy's soil without proper respect for the dead. She had incredible powers, being able to control people and cure blindness.

Mordred, with the Knight Commander, led Morgaine's forces: knights with advanced weaponry and the capability to travel between dimensions.

Morgaine had sealed a a future and/or alternative version of the Doctor called Merlin into the ice caves for all eternity but he escaped. She had been waiting twelve centuries to face him again. (DW: Battlefield)
