It features the introduction of "Batch SW6" — time-displaced duplicates of the regular, adult version of the Legion — who become key participants in a war to free Earth from the control of the Dominators.
In the year 2995, teenage Daily Planet journalist Devlin O'Ryan, who has been accompanying the recently reconstituted Legion of Super-Heroes,[1] is seriously wounded by Dominion soldiers.
When the SW6 Legionnaires discover that Universo has been secretly working with the Dark Circle, they leave his compound and join Jacques Foccart's faction of the resistance.
Dirk Morgna's lover Circe and Legion associate Bounty infiltrate Earthgov headquarters,[9] where they are later joined by Sussa Paka (Spider Girl).
Meanwhile, Jan Arrah (the former Element Lad) learns that his former lover Shvaughn Erin is transgender after she is deprived of the medicine she had been using to become male.
The Earth-based Dominion troops find their resources cut off when their homeworld Elia is attacked by an unknown alien force.
The SW6 Legion works with Troy Stewart (the former Tyroc) and the resistance to stage a massive ruse which permits them to rescue the freedom fighters trapped at the underground chambers in Metropolis.
However, Grinn — a resistance member loyal to Universo — activates the chambers' self-destruct device, killing the metahumans in the Dominion pods.
Searching the wreckage, the young Legionnaires locate several survivors, including sorcerer Xao Jin, Jacques' younger sister Danielle Foccart, the feline metahuman April Dumaka, and the Crystal Kid.
Circe (the former commander of Science Police Earth) uploads a virus into the Earthgov computer network, eventually purging the entire Dominator military intelligence database.
Her teammates discover the adult Dirk Morgna — who survived the destruction of the chambers, but remains in pain as he burns alive.
