The newly formed Agents of S.M.A.S.H. - including a Hulked out Rick Jones, aka A-Bomb - invade the Negative Zone to stop Annihilus once and for all.
The explosion caused by the fight against Annihilus' army has turned Rick Jones into A-Bomb (a blue version of Abomination). With the help of She-Hulk, Hulk and A-Bomb travel to the Negative Zone to rescue Red Hulk and defeat Annihilus. In the end, when Hulk also rescued Skaar, he discovers that he is involved with someone else besides Annihilus.—Wikipedia
