As a member of the Legion of Superheroes, you soon found yourself close with your fellow Legionnaire, Triplicate Girl. However, an invasion from Imperiex, a warlord from the future, decimated the Legion. The tower is in ruins, allies are captured or gravely injured, and as for Triplicate Girl....
The anti-matter waves used to reset the future after he came through went out of control and in the process, DESTROYED Triplicate Girl's white half.
As you all regroup at what's left of the Legion's tower, you walk out to get some air before you see both the orange and purple Triplicate Girls mourn and sob to themselves, trying in vain to comfort one another before merging again. However, wherever Luornu would have white on her, there was instead black.
