History
When Maestro first conquered the Sakaar region of Primary Earth, Tony Stark, Steve Rogers, Bruce Banner, Jim Rhodes and Valkyrie organized a revolt against his tyrannical rule. Unfortunately, it in disaster. Using a gladiatorial control disk, Maestro temporarily took control of the Hulk, making him lose control and kill Tony. The rest were devastated and abandoned the cause, retreating into seclusion across different corners of Sakaar. Captain America faked submission to Maestro by agreeing to train gladiators for his arena games, while in truth secretly preparing an army for the future rebellion.
In time Valkyrie was inspired to pick up the fight once again and sought out Rogers, whom she believed to have turned over to Maestro's side and was relieved to learn the truth. With her assistance, Captain America rallied his most trusted lieutenants, such as Korg and Miek, to lead the gladiators against their slave masters. The Warbound were initially successful, only to have their advance stopped when Maestro send his champion Ares to deal with them. Ares accomplished this by personally confronting and killing the Captain, forcing the rest to flee and regroup.[1]
