She is voiced by Hynden Walch who also voices Starfire.
Argent is a super heroine hailing from New Zealand, whose backstory in the series is never really explored. She was evidently well-known enough to be a recognized hero by the Teen Titans without having met them previously. Because of her super powers, she was targeted by the Brotherhood of Evil for capture and elimination, and in order to ensure her safety and to connect the Titans around the globe, Robin instructed Starfire to give her a T-Communicator to contact the Titans if she ever met danger she could not handle. Soon after having Starfire's help in fixing a breaking dam in her homeland, however, the Brain set his plans in motion, and Argent was attacked by General Immortus and his robot army. Outnumbered and surrounded, she was eventually subdued and flash frozen as a victory trophy in the Brotherhood's headquarters. When Beast Boy and the remnants of the Titans conducted a massive assault on the base, Argent and the other captives were freed by Más y Menos and joined the fight; she subsequently defeated Johnny Rancid in the fray. After their victory, Argent joined the other Titans in visiting Titans Tower and subsequently assisted them in recapturing Doctor Light.
Argent seems to be very quiet, calm, honorable, and very collected. She usually tends to keep to herself and seems to have a bit of a dry and sarcastic sense of humor. Argent is also a bit of a goth or punk as black is her favorite color. Despite being a solo hero and a bit of a loner she is grateful when someone helps her. As typical of being a super heroine she has a strong sense of justice and works hard to protect the innocent and punish the guilty.
She tends to maintain a calm and cool exterior in her duties as a heroine. She is also very collected and seems to think first before acting. Despite this, when fighting and clearly at a disadvantage Argent can become less calm and collected as seen in the urgency of her distress signal to the other Titans. Despite this, she is no coward and would rather fight to her last breath than surrender to a villain.
Argent can however be slightly arrogant however, as she initially underestimated General Immortus when it seemed he was attacking her by himself. When his army appeared she was clearly shocked upon realizing how outnumbered and outmatched she really was. She also put a fighting mode look on her face possibly to scare her opponents.
