Superman falls for a joint conspiracy between his archenemies Darkseid and Braniac. Through technological nanite manipulation and some mental reforging, the two powerful entities were able to rebuild the man of steel into a willing, obedient servant to Darkseid's machinations. While still retaining much of her old powers, the new being has been enhanced to share essence of her new master, to both bolster her already impressive capabilities, but also strengthen her endurance so that she would be able to perform her other, more pleasurable, responsibilities to her Lord.
