Iron Man & Hulk: Heroes United (2013)

Two of Marvels biggest superheroes team-up for a super-charged adventure in Iron Man/Hulk: Heroes Unite. When a Hydra experiment to use the Hulk to power a new reactor goes awry and creates a being of pure energy called Zzzax, who then attacks the power-grid, the Hulk and Iron Man team-up to stop him. The plot is a little thin and is patted out with superfluous fights that go nowhere. Still, the fights are pretty entertaining and allow each character to show off their powers. And the voice actors do a good job, and the score brings a lot of energy to the film. The animation, however, is a little rough; particularly in the texturing and fluidity of movement. Yet despite its problems, Iron Man/Hulk: Heroes Unite is a fun animated feature that Marvel fans will enjoy.
