On Ysmault, Atrocitus is in a massive pool of blood, when he hears something like a wardrum beat. He sees a Red Lantern Ring, crystalized from the blood of the Five Inversions, whom he killed to form the pool. Allowing the ring to attach onto his finger, it quickly takes over his heart’s functions, and spoils the blood in him, replacing it with liquid rage. Atrocitus rises to the surface of the pool, where the Red Lantern Central Power Battery is located. A Red Lantern Power Battery rises from the pool, and Atrocitus uses it to power his ring, becoming the Red Lantern.
