Topaz was the Grandmaster's personal bodyguard and head of the Sakaaran Guards, who had assisted him in overlooking the prisoners involved with the Contest of Champions. When a riot had broken out involving several former prisoners, as well as Thor and Valkyrie, Topaz led her soldiers in fighting back, only to eventually lose her life due to Bruce Banner's actions.
Topaz worked as the Grandmaster's bodyguard present. When Valkyrie presented Thor to the Grandmaster, Topaz revealed her blatant dislike toward the Asgardian bounty hunter. She tried in vain to have Valkyrie's reward reduced. The Grandmaster then decided to execute Sakaaran in attempts to intimidate Thor, Topaz hands the Grandmaster his melt-stick, commenting that the liquefying corpse smelt like burnt toast.
- "Revolution? How did this happen?"
"Don’t know. But the Arena's mainframe for the Obedience Disks have been deactivated and the slaves have armed themselves."
"Oh, I don't like that word."
"What word? "Mainframe"?"
"No, the S word."
"Oh, sorry. The prisoners with jobs have armed themselves."
"Oh, that's better."
- ―Grandmaster and Topaz[src]
When Thor, Bruce Banner and Valkyrie instigated a rebellion on Sakaar, they armed the Grandmaster's slaves with weapons. Topaz reported this back to the Grandmaster, as the Revengers tried to escape. Topaz chased down the Revengers, who were fleeing in the Commodore, one of the Grandmaster's pleasure crafts, Topaz chases after them in her own fighter ship, intending to take them down under the Grandmaster's orders. Though it would've appeared that she seemed to have them on sight, Banner accidentally released the pleasure craft's fireworks, disorienting Topaz and causing her to crash, killing her.
Topaz is very loyal to Grandmaster and always loyally does all his orders. She is highly polite and sophisticated. Topaz takes her job extremely seriously and looks for the prisoners when they escape. She is very willing to administer punishment on the Grandmaster's behalf using the Melt Stick and was even overenthusiastic about using the weapon. She is also very arrogant and confident. It was her fatal weakness, which eventually led to her demise due the actions of Bruce Banner.
