These issues finally tell us what happened after the Gamma Bomb dropped, when the world thought The Hulk died, and before he became Las Vegas’ Mr. Fixit.
Turns out, a wizard from Jarella’s world for some reason knew he was about to get hit with the bomb and transported him back to her world, where both she and Hulk are “dead” and are worshipped as the martyr figureheads for a cult. And now they need Hulk to save them from bad guys and a giant boar.
Hulk goes along with it, saves the people, and then is worshipped as a hero.
Until someone gets jealous and sends him back to Earth.
