Hired by Ronan
Since the Sakaarans were considered close friends with the Kree, the Sakaaran mercenaries were hired by Ronan to aid him in his goals of destroying the planet Xandar as he finds the Kree-Xandar treaty to be an embarrassment for his Kree belief. Striking a deal with the infamous warlord Thanos, Ronan sends over Gamora and Korath the Pursuer to steal the Orb (containing an Infinity Stone) so that Thanos would use it to destroy Xandar for Ronan.
Searching for the Orb
However, the orb was stolen by Peter Quill (the protagonist of the film), who ends up being jailed alongside Gamora, Drax, Rocket Raccoon and Groot. Ronan eventually learned that Gamora actually intends to deliver the Orb to the Collector, so he summons Nebula and the Sakaaran mercenaries to track her down and kill her. They tracked Gamora down to a prison, where they learned that Gamora has already escaped with the Orb and intending to deliver to the Collector as promised. As such, Ronan angrily orders the Sakaarn mercenaries to burn down the prison, killing all officers and inmates in the process.
However, Ronan was able to track down Gamora thanks to a message from Drax, who intends to kill him for the death of his family. As Ronan easily defeats Drax, Nebula managed to steal the Orb. With the Orb finally in his place, rather than delivering it to Thanos, Ronan instead fuses the Stone with his hammer, intending to destroy Xandar himself before killing Thanos.
As Ronan sets his ship to invade Xandar, he gets the Sakaaran mercenaries to fire up the ship's weapons systems against the planet; even several Sakaaran pilots resorted to suicide attacks to take down their enemies. Fortunately, Peter and his friends brought in the Yondu Ravager Clan (led by Yondu Udonta) and the Nova Corps to help fight off all of the Sakaaran mercenaries to their deaths. Despite the losses of Korath and the mercenaries, as well as the departure of Nebula, Ronan turned the tide of the battle by using the Stone to defeat the Ravagers and Nova Corps armada, though the Guardians managed to retrieve the Stone and use it to kill Ronan for good.
