Maelstrom is back (after a short one issue rest)! And the master of kinetic energy has a new plan to destroy the world! Slow down the rotation of the Earth and create a global catastrophe!

In the skies over Tierra del Fuego, eleven of Earth's Mightiest Heroes battle Helio, Phobius, and Gronk! And if the Avengers get past those three lackeys, then Maelstrom awaits! A giant-size Maelstrom! Can the east coast and west coast Avengers knock down the malevolent Maelstrom and save the planet? Avengers Assemble!
