Skaar

Skaar is the savage son of the Hulk and Caiera the Oldstrong, born from the volcanic chaos of the alien planet Sakaar. Conceived during Bruce Banner's time as a gladiatorial champion and eventual king on that war-torn world, Skaar inherited the gamma-fueled rage of his father alongside his mother's ancient power — the Old Power, a mystical force tied to the very stone and soil of a planet. This explosive combination makes him one of the most formidable gamma-powered beings in the Marvel Universe, equally at home wielding a massive stone sword as he is smashing through armies with his bare fists.

Skaar's first appearance in What If? Planet Hulk #1 (2007) is an important early collectible for Planet Hulk and World War Hulk era enthusiasts, though his true canon debut and ongoing story unfolded in the pages of Skaar: Son of Hulk, which launched in 2008. That series established him as a warrior raised in brutal conditions on a dying Sakaar, hunting prey and building a reputation as a merciless killer of killers long before he ever set foot on Earth. His journey from feral alien savage to reluctant participant in Earth's superhero landscape gave writers rich material to explore the nature of inherited rage, legacy, and identity — themes that resonate strongly with fans of the Hulk mythos.

One of the most compelling arcs for collectors surrounds Skaar's calculated infiltration of Bruce Banner's life, secretly plotting vengeance against his father while posing as an ally. This storyline ran through Dark Son and connected deeply into the broader Hulk titles of the era, featuring brutal confrontations and emotional revelations that redefined the Banner family dynamic. Skaar has also crossed paths with the Dark Avengers, served alongside the Warbound — his father's loyal allies from Sakaar — and later appeared in Gamma Flight and S.M.A.S.H. storylines, cementing his place across multiple corners of the Marvel Universe.

For collectors, Skaar represents a character with serious upside. His key issues span a unique crossover moment in Marvel history when the Planet Hulk and World War Hulk events were reshaping the entire Hulk corner of the line. First appearance copies, the debut issue of Skaar: Son of Hulk, and his early cameos in main Hulk titles are all worth tracking down. As gamma-powered characters continue to play major roles in Marvel media and publishing, Skaar's distinct look, powerful origin, and deep ties to one of Marvel's most iconic characters make his back issues a smart and satisfying addition to any serious collection.
