Son of Hulk #13
In "Problem Child," the fate of Sakaar hangs in the balance as its crumbling world collapses after the Old Power is devoured by Galactus. Amid the chaos, a group of survivors flee into space, uncovering a shocking truth: Hiro-Kala, long believed to be a mere slave, is actually the true son of Caiera and the Hulk—making him the rightful heir to Sakaar, not Skaar. Written by Paul Jenkins and illustrated by Andres Guinaldo, with inks by Vicente Cifuentes and colors by Jean-Paul Beaulieu, this issue redefines legacy with a revelation that reshapes everything. The cover, by David Palumbo, captures the moment with haunting intensity.
