The Illuminati sent the Hulk on a mission to space to destroy a sentient satellite, but the mission was also a trick to relocate him to an uninhabited world where he could find peace. Instead, he went off-course and landed on the savage world of Sakaar which challenged even his immense strength and invulnerability. Despite months of adversity, the Hulk became the planet’s ruler and even found love with Caiera the Oldstrong, bearer of the earth-controlling Old Power.
When the warp core of the Hulk’s ship exploded, it destroyed Crown City and killed almost everyone there, including Caeira and her unborn child. This spurred the Hulk to leave Sakaar with his Warbound allies and seek revenge on Iron Man, Doctor Strange and the Illuminati on Earth (all during PLANET HULK). Little did he realise, his son was alive and would emerge from the fire pits of Sakaar thirsty for destruction (during WORLD WAR HULK).

Escaping to the surface after his father had already left the planet, the misshapen son of Hulk – who named himself Skaar – spent a month fighting and killing to survive and witnessed the violence of the Fillian warriors of Axeman Bone who killed all the children they encountered children to prevent the prophesied emergence of the Hulk’s offspring. 1st appearance: Fillians |
