Todd Rice was built as a part of Infinity Inc, but went on to find a great deal of success in the lager DC universe as both a villain and as a member of the Justice League. While never a hugely popular character, he nevertheless maintained a continual presence for many years.
We've followed along with that story fairly closely, making him first a member of the reformed Justice Society, but then having him join the Justice League after the death of his father. He was present during the attack of the Hyperclan in Grant Morrison's JLA, and we've kept him as a part of the league that is attacked by the White Martians. Other than that, we haven't changed much about him. Even his costume is one of the most consistent in comics, although we really love this redesign by Deviantartist payno0.
Just a quick note about Todd's sexuality. For some time, he was one of the highest profile gay characters in comics. after he was removed from continuity by the new 52, DC made a huge deal about the fact that a huge character was going to be revealed as gay. Eventually we learned, it was Green Lantern. Not current Green Lantern Hal Jordan, mind you, but the newly created Earth 2 version of Alan Scott. so not only was their advertised "major character' not really major at all, but this new reveal that Alan was gay made it very unlikely that we'll ever see Obsidian or his sister jade in modern continuity. So effectively, DC wiped one gay character out, put in another, and then expected a pat on the head for it.
