Marvel Animation Studios unveiled a first look at Iron Man & Hulk: Heroes United at New York Comic-Con Saturday, debuting the first trailer for the CG movie.

The plot involves two HYDRA scientists giving Tony Stark’s arc reactor technology a makeover using the Hulk's gamma energy. The scientists end up unleashing a bad guy called Zzzax, whom Iron Man and the Hulk must take down.

It looks like the pairing of Marvel’s (arguably) brainiest hero and its most brutish could make for some good comedy. There’s some banter in the trailer, including Iron Man thanking the Hulk for an assist, which resulted in Stark “only” receiving a few broken ribs.

The movie will be on sale April 23, 2013 on Blu-ray, DVD and digital download.

Watch the trailer below.
