Power Battery, located on Oa, is the repository for billions of years' worth of willpower in energy form. This energy has been harnessed and focused by the Guardians and is tapped by each GL's power battery. This in turns feeds it to their individual power rings. By applying willpower and concentration, the ring is literally able to accomplish anything of which the wielder can conceive, and is therefore as limited or limitless in abilities as the wielder. In Kilowog's case, he has shown an affinity for creating astoundingly complex machinery using the ring. In terms of combat, Kilowog tends to eschew the "giant boxing glove" fighting style of Hal Jordan and mainly uses his ring to fly and to absorb any enemy's attacks long enough for him to get close enough to batter them into unconsciousness. According to the 2005 miniseries Green Lantern: Rebirth, Kilowog's ring is the only one that Hal Jordan knows of that makes a sound when being used. In addition to his power ring, Kilowog possesses the natural super strength and durability of his species, as well as a powerful intellect that surpasses many of his fellow corpsmen. Under mind control, Kilowog even manages to combine all of these abilities to easily hold his own against Superman. Other versions Elseworlds Kilwog appeared in various Elseworlds tales: including JLA: The Nail, its sequel, Batman: In Darkest Knight, and Superman: Last Son of Earth. Flashpoint In the alternate timeline of the Flashpoint event, Kilowog is killed by Nekron. Fourth Reich In an alternate future where the Earth is controlled by Nazi supermen, Kilowog is one of the thousands of Green Lanterns to participate in a rescue mission. All who participate are slain. Planetary In an alternate universe ruled by evil versions of the 'Planetary' heroes, Kilowog's corpse is one of many Green Lanterns on display in the Planetary headquarters. Injustice: Gods Among Us During the Year Two series, Kilowog and a group of Green Lanterns are sent to Earth to retrieve Superman, who has undergone a transformation into the new ruler of Earth. He and the other Lanterns engage in a battle, seemingly winning until Sinestro kills the Lantern Ch'p and the Green Lanterns are rendered helpless. Not willing to kill them but not wanting to send them back to the Guardians, Superman chooses to take them as prisoners of war. Kilowog and the Lanterns are not seen
