A new Terra named Atlee appears in "Supergirl" #12 (January 2007), sporting a new outfit and black hair. She emerges near a party Supergirl is attending, fighting a creature from a civilization under the Earth's surface. While Supergirl expresses disdain for the superhero activities which interfere with her personal life, Terra counters by saying that being a superhero is simply the right thing to do; she does not comprehend Supergirl's complaints. Together they defeat the monster by collapsing the ground under it. Terra then departs. The "Terra" miniseries revealed that she is a member of an alien race called Stratans who live below the Earth's surface in a massive cave called Strata which is actually the empty spacesuit of a long dead cosmic extraterrestrial, and possesses a rare mutation granted by a unique ore called "quixium" that grants her the earth powers she wields.
