If you saw the preview for Superboy #1, and thought the the red-head with the round-rimmed glasses looked familiar - turns out you were right!
Bleeding Cool has it on good word from a disgruntled(?) ex-Wildstorm employee that this is none other than Fairchild from Gen 13!
In the WildStorm U., Caitlin Fairchild had the ability to augment her size and strength exponentially, in addition to invulnerability, leading her to become one of the most powerful! She even had the ability to absorb the powers of others.
It is unknown how much Superboy writer, Scott Lobdell will retain from the WU, but Fairchild would certainly make a great ally for Superboy - or opponent!
