John Walker was the field leader of the Invaders and America's first super soldier. He appeared in The Invaders and was played by John Barrowman.


John is in his 40's and has short brown hair and a fair complexion. He often wore a black Kevlar battle suit similar in appearance to Steve Roger's first costume. He usually wore a trench coat over it.



  • Walker's film portrayal has some inspiration from Captain Jack Harkness from BBC's Doctor Who.
  • In the comics, Captain America and Bucky led the Invaders, not John and Lamar.
