Hulk #30

The cover of Hulk #30 makes a bold visual statement: a single massive figure split down the middle, half green Hulk and half Red Hulk, fused into the Compound Hulk — and the cover text makes no secret of the introduction. Ed McGuinness's cover art crackles with electric energy radiating behind this combined behemoth, both halves snarling with raw fury as fists thrust toward the reader. Billed right on the cover as a "Gamma-Sized All-Battle Issue," this 2011 Marvel entry promises wall-to-wall action between two of the most powerful bruisers in the universe.
