Incredible Hulks: Dark Son
All his life, the Hulk has wanted to be left alone - but now, he's got a big, bad family to keep up with! After the events of WORLD WAR HULKS, Hulk is joined by his son from "Planet Hulk," Skaar; his daughter from an alternate future, Lyra; the cousin he's known and loved for ages, She-Hulk; and his best friend, Rick Jones, now in the gamma-charged form of A-Bomb.
Oh, and don't forget his first wife and longtime love, Betty Banner - transformed into the ragingly embittered Red She-Hulk. They'd better stick together no matter how uncomfortable this new arrangement may be for all concerned, because one more addition to the family is making his way across the galaxy: the world-shattering Hiro-Kala - twin brother to Skaar, son to Hulk and unknown to either. But not for long!
