In the opening sequence of the first season, the Hulk picks up an Infinity Fractal, and is transformed by its power into something different every episode. This feature was later removed for the second season. Additionally, each episode's title card is an homage to a classic comic book cover, as are some of the episode titles.
The Super Hero Squad fights to keep a fractal away from Doctor Doom when he sends Mole Man and his monsters and Fin Fang Foom to attack Super Hero City. Meanwhile, Mole Man incorporates the fractal into his stick, gaining super-speed and mind control powers.
The squad gets frustrated when Silver Surfer cannot get the hang of Earth customs. Doctor Doom sends Abomination and MODOK to capture the Silver Surfer to siphon his cosmic power. The Super Hero Squad and the Thing set out to save him while Doom uses the siphoned Power Cosmic to meld his various fractals together into a Fractal Dagger.
During a chaotic battle with Klaw and Screaming Mimi, a fractal's cosmic power turns the Hulk into the Gray Hulk. His new form makes him highly intelligent and pacifistic, and believing the Super Hero Squad to be childish. To redeem themselves, Klaw and Screaming Mimi rendezvous with Melter and Toad to find a fractal at the local reservoir.
