Namorita returned to Atlantis, only to be denied entry as the Atlanteans discovered her clone nature. This seemed to be the final catalyst for Nita. 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. Because of this, Namorita gave herself the name Kymaera. While fighting alongside the Warriors, she was captured and brainwashed by a terrorist organization, only to be rescued by Night Thrasher (who received a tip from the Mad Thinker).
