Patricia Tannis

Biography
Tannis was born to two blue-collar isotope designers. Her mother died around 16 years before Patricia began her expedition to Pandora.

She became Dahl's chief scientific advisor, assigned to Pandora to find abandoned alien technology as a response to Atlas discovering Eridian ruins on Promethea. On her first day on the planet she believed the existence of the Eridians to be simple 'myths and legends' and considered her expedition a waste of her scientific talents.

Her emotions were deadened as half of her staff were eaten alive and killed by skags after relocating her base, her survival only granted by hiding under the body of a colleague, Carl, as he was devoured. She took his comfortable chair after his death, at which point she noticed a glow on the rocks at the dig site.

She met the Vault Hunters after Helena Pierce sent them to her, knowing both parties were searching for the Vault. The Vault Hunters brought the piece of the Vault Key that they had discovered, and left it with her to run tests on it. She asked Pierce for Class A clearance for the Vault Hunters, and was denied. In response, Tannis stole Pierce's robotic arm and kept it until clearance was given.

When the Destroyer was killed. the Vault Key was given to her to look after.

During the CL4P-TP uprising on Pandora, she recruited the Gen 1 Vault Hunters to accuire parts from them in order to build a robot companion for herself.

After Handsome Jack and the Hyperion Corporation took control over Pandora, Tannis joined the Crimson Raiders.

After Angel's death, her Siren power of phase shifting was passed on to Tannis.
