It's a good thing beach season is over, because Marvel Comics' newest team just made going into the water a lot more dangerous. Namor the Sub-Mariner has launched his latest crusade against the surface world with the Defenders of the Deep, a new team of underwater warriors.
For Marvel's Atlantis, the last few years have been pretty rough, and Namor and his fishy friends finally reached their breaking point in Avengers #9. Despite a devastating war with Wakanda, the end of the world, and being raised to the ocean's surface, the King of Atlantis and his subjects have rebuilt their undersea kingdom time and time again. However, much of Atlantis was devastated once again in recent weeks when the body of an impossibly big Celestial fell from the stars and crushed it. When Atlantean refugees and warriors were mocked and executed by the surface world, the Sub-Mariner declared open season on "air-breathers."
While Namor has always flip-flopped between being a hero and villain, he's rarely been this serious about attacking anyone who doesn't have an address near SpongeBob SquarePants' home. In the past, Namor has flooded Manhattan and launched a few invasions on dry land, but this time is different; now, he wants to exercise his home-field advantage and kick humanity completely out of the oceans.
While this conflict will partially play out in Marvel's upcoming Invaders series, it's already started in the pages of Avengers. In Issue #9, Namor sends his War Sharks to chow down on his old pal, the ex-Avenger Stringray, and takes on the Avengers all by himself. For whatever he has planned next, Namor will get some help from the Defenders of the Deep.
