After the Hulk turns to Banner, Bruce Wayne offers to hire him to build the replacement of the stolen gamma ray gun. Meanwhile, we see the Joker using the Gamma Ray to try to “cure” the Shaper of Worlds (who is revealed as the source of the strange events at the beginning) and the Joker reveals that is goal is to use the Shaper of Worlds to make the universe as crazy as he is.
While Banner is working for Wayne Industries developing the new gamma gun at a ship at sea, the story offers us a hidden gem: in a very funny moment, Alfred offers Banner some tea: “perhaps a spot of tea will calm your nerves, Dr. Banner”… why didn’t anybody think of that before!
The Hulk is then captured by some military types, that we later find out that are operatives sent by the Joker and the Shaper of Worlds, with the idea to capture Banner to make adjustments in the gamma gun the Joker previously stole, to cure the Shaper. The Hulk manages to escape, but the Shaper decides that the cure to his ailments may not be the gun, but the power inside the Hulk himself.
The Joker convinces Batman that they have to find the Hulk to stop what’s happening, and after following him flying tied to Hulk’s ankle by his bat-rope, Batman faces the Hulk again. This time, Batman tries to do the same gas trick on Hulk, but with a single wave of his arm the Hulk disperses the gas.
The Hulk then throws a car at Batman, who manages to escape certain death by jumping through both it’s windows. Batman tries to avoid the Hulk’s wrath by throwing some smoke bombs to hide himself, but Hulh smashes the down the whole building!
