Halo

"Halo-Girl" is a Quraci refugee living in Markovia.

History
The refugee was avoiding the royal guards inside the palace, while holding a silver platter in her arms. She made her way to the exit and dialed the security code to unlock a door. As she opened it, two assassins stepped inside: one speeds away into the palace and the other knocked the befuddled refugee out.

At some point afterwards, the refugee was put through the Tar protocol but died.

Her dead body was thrown inside a grave by Henchy, Johann Mintz and Piotor Platz, along with other failed Tar subjects. But as she was being covered up, a purple aura beamed from her and she sprang back to life. She tried to climb out of the grave, but Henchy and his men attempted to bury her alive. Fortunately, Tigress intervened and fought Johann and Piotor. When Henchy tried to use an energy whip against them, the refugee unwittingly generated a red force-field, causing his whip to bounce back and knock Henchy out. She ran off with Artemis.

The girl was largely discombobulated and had no memory of what had happened before the grave incident. She could speak English, albeit with some difficulty.

Artemis instructed the still unnamed girl to stay with Sphere while they rescued Superboy. As she watched Artemis and Jefferson Pierce walking towards the cliff, she said "kill".

She followed them inside with Sphere, and when Plasmus was about to strike a deadly blow against Artemis, the girl shielded them with her red-aura power, firmly stating "no kill". Artemis was happy she didn't stay behind, despite her instructions, and dubbed her "Halo-Girl".

She made an escape with the Team, but Count Vertigo was able to track them down. In the ensuring skirmish, Halo-Girl manifested another aura–an orange one that allowed flight–when Plasmus grabbed her and burned half of her face off, though she didn't die and was able to heal herself back to normal with her purple aura.

After Plasmus–now released from Vertigo's control–was shot dead, Halo-Girl tried to heal him, but he was dead and could not be resurrected.

Background information

 * In the comics, Halo was an original member of the Outsiders with photokinetic powers. Violet Harper was a runaway who lived a life of crime, until an altercation with Tobias Whale and Syonide killed her. Her essence was merged with an alien Aurakle, essentially resurrecting her. Plagued with memory loss, she started using the name "Gabrielle Doe". Her original body was later revived by Kobra as Spectra.
 * This is Halo's second animated appearance. She appeared, with no lines, in Batman: The Brave and the Bold.
