Namor was sent to New York after divers were found near Atlantis. However, it was revealed that the divers were Nazis, and Namor joined the Invaders,[31] fighting in World War II alongside men such as Captain America and the android Human Torch (in addition to his solo missions), and later the All-Winners Squad to oppose the Axis. Namor would at times battle, then befriend, the democratic societies of the surface; the explanation for this was later discovered to be temporary insanity as a result of too much time spent away from the sea. For the most part, however, the Sub-Mariner set his sights on Nazi Germany and Imperial Japan. The Atlanteans became involved with the Axis-created Human Torch duplicates the Firebrand Squadron. One Atlantean, his friend Meranno, became an Axis agent known as the U-Man.[citation needed]
