23 years ago - 13-year-old Stealth's planet is invaded by the Citadel. she is given to them as an offering, and after her powers are analysed, she is placed in the Starlog.
19 years ago - 17-year-old Stealth escapes the Starlog with Vril Dox, & joins L.E.G.I.O.N. She is given a name for the first time in her life.
now - 36-year-old Stealth joins Adam Strange's Omega Men alongside Vril Dox in order to fight back against Lady Styx.
Stealth is a very singular creation within the ranks of the L.E.G.I.O.N. she's never appeared anywhere else. She's designed to be their resident ingenue character, although she's gone on to be quite a bit more; developing a unstable biological drive that forced her to mate with Vril Dox. The less that is is said about that storyarc the better.
Meanwhile, she goes on to have a child with Vril, which actually is a pretty cool story, but our version of Vril is meant to more closely mirror Brainiac, so he will eventually create clones of himself rather than have biological progeny.
Interestingly, Stealth really isn't given much of an identity outside of her role as mate to Vril Dox, not even her own name. She might be a character deserving of a larger role in the DC Universe at large at some point, if only to see what some really great writer might make with her.
