History
Nubian Prince was the Black Panther altered by Morgan Le Fay's reality distortion wave. The wave caused the time period to be altered to a medieval setting altering the Avengers' clothing, speech patterns and thought processes. All of the Avengers involved believed themselves to be a part of the Queen’s elite guard known as the Queen's Vengeance. [1]
The Scarlet Witch, with the combined willpower of all the awakened Avengers, pumped power into Wonder Man, shifting reality back to normal, and defeated Morgan in the process.[2]
