The Invaders were created by Roy Thomas and Sal Buscema in Avengers #71. Thomas continued to write their own self-titled book, while Frank Robbins was the first artist. The Invaders originally consisted of Namor, Captain America, and the Original Human Torch and were retconed as a WWII team. They were partially inspired by the real post-WWII, Golden Age team, the All Winners Squad, and shared a few members. Bucky and Toro were added to the team in the first issue of the book. The next members to join the Invaders were Union Jack and Spitfire. Later, Miss America and the Whizzer would join. Following that the Invaders would dissolve and become the All-Winners Squad following the war.
