[9] In the crossover story arc Atlantis Attacks, Namorita allies with the New Mutants, who accidentally found the Horn of Doom and gave it to Namor.

He entrusts Namorita to guard it in her quarters in Atlantis, but three Deviant Mutants steal them by order of their leader Ghaur and his ally Llyra.

[10] A short time later Namorita was abducted by Deviants and reappears in the final battle of this story arc, when Llyra nearly succeeded in tricking Namor into killing her.

She was joined by five other young superheroes, and after Nita and Nova subdued Terrax by severing his contact with the ground, the six formed the New Warriors.

[15] She and her fellow Warriors first battled Psionex,[16] then fought the third Star Thief and journeyed to the Blue Area of the Moon, where they encountered the Inhumans Royal Family and the Watcher.

[21] However, the stress of leading the Warriors, the revelation of her cloned nature, and ruling Atlantis during Namor's absence all proved to be too much for her.

An over-saturation of oxygen, coupled with the DNA Vyrra spliced into her at the time of her creation, caused her to change into a closer version of the original Atlanteans.

[25] While fighting alongside the Warriors, she was captured and brainwashed by a terrorist organization,[26] only to be rescued by Night Thrasher (who received a tip from the Mad Thinker).

Her lover Nova saw her in this state and did not speak in time to reassure the emotionally vulnerable Namorita that his feelings for her had not changed.

[30] After her breakup with Nova, Namorita briefly dated Johnny Storm (the Human Torch),[31] and co-ruled Atlantis in a Council of Three with Warlord Seth and the warrior Andromeda.

Namorita was among the four New Warriors whose actions sparked the public backlash against masked superheroes which is at the core of Marvel's Civil War.

[33] Subsequently, she was listed as "deceased" on the website revealing the secret identities of the surviving members of the New Warriors,[34] and Speedball is then confirmed as the only survivor of the blast.

[36] When the Invisible Woman asks for help from Prince Namor, he tells her that the only reason he would help is due to Namorita's death, and he has already avenged that.

[37] Namorita's remains, along with Dwayne's and Microbe's, are later recovered by the New Warriors and Justice's Counter Initiative team, and given a proper burial.

[41] While having slow adjustment to her rebirth, Namorita was kidnapped by the Revengers, a facsimile of the Avengers originating from the Cancerverse, after determining that she was a quantum anomaly.

As part of the effort against the Cancerverse, she teamed up with an aged version of her old ally Vance Astrovik, otherwise known as Major Victory.

Deirdre Kaye of Scary Mommy called Namorita a "role model" and a "truly heroic" female character.

Namorita joins the Beast's hastily assembled mutant hero team - consisting of herself, Theresa Cassidy, who named herself Banshee in honor of her late father, Rahne Sinclair, James Proudstar, the Scarlet Witch and her brother Quicksilver - to combat Count Nefaria and his Ani-Men, and in the end joins the new X-Men team.
