Skaar: Son of Hulk #8 2008

The first time the Silver Surfer came to Planet Sakaar, he was enslaved as a gladiator and became the most terrifying combatant the Great Games had ever seen. But now the whole globe trembles -- for the Silver Savage has returned, not as a mere gladiator -- but as the Herald of Galactus, Devourer of Worlds! The children of Sakaar turn to the Son of Hulk for succor -- but what hope have they now that Skaar has allied himself with his father's greatest enemy?
