The Warbound is a group of fictional characters in the . They first joined forces in The Incredible Hulk vol. 3, #94, as a combination of new and existing characters, the former created by Greg Pak and Carlo Pagulayan.
After the Emperor of Sakaar, the Red King, tries to kill them numerous times, the Warbound escaped after the enslaved Silver Surfer was pitted against them in the Great Arena, where the Hulk shattered his one-time ally's obedience disk. Once freed, the Silver Surfer used his returning Power Cosmic to destroy the obedience disks of all present at the arena, allowing the Warbound and many slaves to escape into the Twisted Wood of Sakaar before he himself departed. After a protracted rebellion against the genocidal Red King, the Warbound, the Imperial rebels and the Natives of Sakaar toppled the regime in Crown City with the death of the Red King, placing an initially unwilling Hulk on the throne as the Green King; Korg had concluded that only the Hulk had the strength to hold the many different peoples of the world together.
However, just as everything seems to be going well, the shuttle which originally brought the Hulk to Sakaar malfunctions, causing its warp-core to detonate; the Hulk's wife Caiera, their unborn child, and countless magnitudes of Sakaar's inhabitants died almost immediately. Having pledged to stand and fight side-by-side until the end, the Warbound went with Hulk into the Stoneship (once belonging to the Shadow People), heading straight for Earth to take his revenge on the Illuminati who conspired to blast him into space in the first place, all of which leads to the events of World War Hulk.
The Warbound feature in their own miniseries, entitled World War Hulk Aftersmash: Warbound, in which the Warbound evade S.H.I.E.L.D. capture only to be teleported to New Mexico by the Leader, who used Hiroim's tectonic power to activate a Gamma-powered shield, over a large portion of the desert. They are being chased by S.H.I.E.L.D using information given by an incapacitated and incarcerated Miek to Deputy Director Maria Hill. Trapped inside Gammaworld, the Warbound join forces with a local US Army company to save a nearby town from irradiated (and thus huge) insects, and begin to feel the effects of the gamma radiation themselves. Using Hiriom's Oldstrong power, the group manages to dispel some of the radiation, opening a gap in the Gammaworld dome for the civilians to escape through, but are interrupted by the arrival of a huge, gamma-powered gestalt being composed of numerous townsfolk and a dog fused together by the radiation. The creature, known as Horde, attempts to destroy everyone who tries to leave, but is fended off by Kate Waynesboro, and as the Warbound attacks the Leader, Hiroim tells Korg to kill him in order to destroy the dome. Korg shatters Hiroim and the dome dissipates; however Hiroim reforms, as does the dome. The group are then attacked by S.H.I.E.L.D. sentry robots, which have been placed under the Leader's control. In the ensuing battle, Elloe stabs the Leader in the chest. The Leader then absorbs the Dome's power, turning into a gray skinned giant. Hiroim stops him, killing himself in the process. Before dying he passes on his old power to Kate, who protects the remaining people from an attacking monster. The Warbound haven't been seen since this point and there is no publicly revealed plans to keep their story going.
