Arriving on the Planet Sakaar in a weakened state (due to the effects of traversing the 'Great Portal'), Hulk was subsequently
implanted with an obedience disk. He was thereafter forced to fight in the Great Arena as a gladiator, where the Red King
intervened and scarred the Hulk's face (earning his gladiatorial moniker 'Green Scar') and the Hulk did the same to the monarch,
gaining an enemy in the person of the Emperor himself. After the initial events in the Arena, the Hulk was put through the
gladiatorial tests of the trainer and himself former gladiator Primus Vand, where he met Korg, Miek, the Unhived, the Brood,
Hiroim the Shamed, Elloe Kaifi and her bodyguard Lavin Skee. This ragtag group of outcasts and undesirables became Warbound
early on in their time as enslaved entertainment following the death of Lavin Skee, pledging allegiance only to each other,
which Miek called 'friends fighting for friends'.
After the Emperor of Sakaar, the Red King, tries to kill them numerous times, the Warbound escaped after the enslaved "Silver Savage" 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.
World War Hulk
When Hulk returned to Earth, the Warbound helped to defeat some of the heroes, bringing them to Madison Square Gardens
to witness the defeat of the Illuminati. However, when the final battle between the Hulk and the Sentry began to cause serious damage, the Warbound collaborated with the heroes to help the civilians evacuate, the Warbound being
unwilling to witness another world die. Miek's treachery of genocidal negligence was then revealed, as he had merely observed
and done nothing while loyalist followers of the Red King plant bombs which will trigger the destruction of Sakaar. He had
not intervened because he believed that it was necessary to 'remind' the Hulk that he was a killer instead of a peacemaker.
The Hulk and No-Name the Brood Queen nearly kill him upon learning of this, and the surviving Warbound subsequently surrender
to the government with the Hulk's defeat. They are held in custody by S.H.I.E.L.D but subsequently escaped after Hiroim (with help from Korg and the Thing) prevented Manhattan from breaking in two.
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 teleported to Nevada 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 dispell 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 Waynseboro, and as the Warbound attacks the Leader, Hiroim tells Korg to kill him in order to destroy the dome.
