The Sentinels is a team comprised of The Planet's Ultimate Super-Heroes of the modern Standard Comics Universe.

The team first formed in response to an attack by Cyborilla on the United Nations building in New York in "The Sentinels" #1. The original team consisted of Hydroman, Magno, Man O' Metal, Nelvana, and TNT Todd.

At various times, almost all of the Earth's superheroes have been members of the team.
