First Appearance: New Avengers # 7-2005
Brief History: The group was formed in the aftermath of the Kree-Skrull War.
Initially, the 6 men below were brought together by Tony Stark, so that the Groups may unite and fend off any further attacks such as the one by the brought to Earth by the Kree-Skrull War.
After consideration, the 7 (The Black Panther was an original member who left) decided that it would be best for the 6 of them to share information and discuss how their individual groups would handle such threats.
The group would not last, however. Namor would leave shortly after it was decided to jettison The Hulk into space, Professor X would seemingly disappear in the aftermath of the House of M storyline, and the rest (with the exception of Mr. Fantastic and Iron Man) would dissolve after Iron Man suggested that act in agreeance with the Registration Act in the Civil War Story.
They would reform, but only for a brief period.
