Initially depicted as an ally of Aquaman and the romantic interest of his sidekick Aqualad (Garth), Tula also served as a member of the Teen Titans before being killed in Crisis on Infinite Earths.

While she does not actively adopt the Aquagirl codename, the character assumed significant roles within Atlantis such as a high-ranking commander of a covert black-ops faction, a regent for Aquaman's administration, and as an honor guard during Mera's reign as Queen.

Lorena is a teenage girl who acquires Atlantean-like abilities after being exposed to a serum derived from Aquaman's DNA by an ethically questionable scientist.

As part of a catastrophic event orchestrated by the scientist, a portion of San Diego sinks into the ocean following a triggered earthquake.

In more recent continuities, Tula retains most of her original abilities typically seen of an Atlantean as her previous iterations (breathing underwater, superhuman strength, swimming at extreme speeds, enhanced senses and reflexes) though portrayed at a greater degree and unlike Atlantean, is trained to be able to survive outside the surface for extended periods of time similarly to a human.

[15] Lisa Morel is introduced in Adventure Comics #266 (November 1959) as one of several violet-eyed Atlantean children born unable to adapt to the watery world.

[16][17] Selena is a young Poseidonis teenager who temporarily teams up with Aquaman under the name "Aqua-Girl" in World's Finest Comics #133 (May 1963) to make her former boyfriend jealous.

[20] She is named Tula after her father's late girlfriend and is part of a team consisting of the other original Titans' children who end up taking Batman's side in the story's key conflict.

In her appearances, Tula seemingly demonstrates a partial shapeshifting ability, changing parts of her body to resemble those of sea creatures.

3 #17–19 (2005) by writer Geoff Johns and artist Mike McKone, Lorena is Aquawoman, a member of a future, alternate version of the Titans.

An alternate timeline variant of Tula appears in Justice League: The Flashpoint Paradox as a member of Aquaman's army who is eventually killed in battle against Wonder Woman's Amazons.
