Steven Rogers (Earth-398)

Yeoman America, a knight warrior was Captain America (Steve Rogers) 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 (Earth-398).^[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.^[1]

He was later seen as part of the Howling Commandos, joining the Multiversal Avengers' fight against the Council of Red.^[2]
