A new heroine named the Black Widow joins the team and shows the boys she can kick butt even better than them. But we soon learn she is really the shape-shifting Mystique, sent by Doom to infiltrate and get at the fractals. She nearly succeeds and leads the Squad into a Lethal Legion ambush. But Nick Fury may just have provided their ace in the hole… Screaming Mimi turns on the villains, revealing herself to be an undercover SHIELD agent named Songbird!

It's a super-team team-up as the Squad helps out the Fantastic Four with an ambush from the alien Skrulls and Super-Skrull. Meanwhile, Dr. Doom is making a devious deal with a mysterious cosmic villain named Thanos. As the battle rages in the Baxter Building and outer space, our heroes find that both threats are connected and they may have to make a deal of their own to save the Earth!

Doom's ally, Egghead, hatches a scheme to steal a fractal in the Squad's Helicarrier by shrinking to insect-size. Fortunately, the Squad can count on Ant-Man to help them chase down the villains at micro-scale. But being super-small leads them into some very unpleasant places, including Hulk's nose.

Supernatural wackiness is turning the city (and the Squad) upside-down. The Squad goes to the mysterious Dr. Strange for help, but Strange tricks them into battling the dread Dormammu. It seems a wayward fractal is stuck in the Eye of Agomotto – but can the heroes possibly free Dr. Strange from the fractal's influence, defeat Dormammu and rescue the city from an army of Mindless Ones, all at the same time?

When the Helicarrier is embarrassingly smashed, the Squad needs to find a place to crash. The team proves none too welcome at Stark Industries, the Punisher's battle van and Reptil's bedroom. Dr. Strange takes them in, but they dread a creepy, wacky night in his Sanctum Sanctorum. And thanks to the Enchantress, there is even more magical mayhem than they bargained for.
