Lorena Marquez (2004-current)

A young woman from San Diego who was one of thousands to find themselves submerged when the city was torn apart by an earthquake. Like many of the survivors, she found she could breathe underwater thanks to the experiments of a man named Geist.

With the help of Lorena, Aquaman sought out the remaining survivors of San Diego. They located a number of survivors as well as the man responsible for their condition: a scientist named Geist. Geist used Aquaman's DNA to introduce a genetic anomaly into the San Diego water supply. This self-replicating strand of DNA converted the populace's respiratory, auditory, ocular and muscular systems to a more marine-based model. This experiment was done in the name of science - Geist's effort to save humanity from the upcoming global warming. Geist was financed by a mysterious corporate benefactor , whose identity remains a mystery. The corporation had caused the quake which sunk San Diego to test the results of Geist's' experiments.

When Ocean Master used mystical means to switch lives with Aquaman, Lorena assumed the role of Aquagirl in the new twisted reality. After Aquaman exposed his scheme, Lorena decided to keep the costume she had acquired. She had, in essence, become the new Aquagirl.

Aquagirl joined the Teen Titans for a short time, but later quit. The group remained in constant disorder until Robin returned and reorganized the Titans into a cohesive team.

In the "Titans Tomorrow" future storyline, Lorena has telepathic powers, but whether or not Lorena will develop these abilities in the present remains to be seen.

Aquagirl is a member of the Teen Titans during the events of 52. She assisted Steel in launching an attack on Lexcorp when Natasha was captured by Luthor.

Since the destruction of Atlantis, her whereabouts have mostly been unknown, but she did briefly join up with the Teen Titans (Volume 3) in the turbulent year that followed. In Teen Titans #34 Lorena is shown at Titans Tower arguing with Hawk.
