Justice League: Red Justice by Michael Teitelbaum

The Justice League has been called to the Ural Mountains in Russia where a decaying nuclear reactor threatens to melt down. The heroes are able to shut down the reactor, but in doing so they also cut off the power to a long-forgotten cryogenic lab hidden deep under the mountains. A group of genetically engineered meta-humans frozen in the lab are revived. Code-named Red Dawn, they are endowed with powers that rival and mirror those of the Justice League. The Justice League has finally met its match–unless the Flash can save them in time.
