Kilowog is a fictional superhero from DC Comics, and a member of the Green Lantern Corps.

Biography

Origins
A towering alien with a brutish cross of porcine and bull-doggish appearance, Kilowog is renowned throughout the Green Lantern Corps as the primary trainer of the Corps' newest recruits. The Guardians of the Universe recruited Kilowog, a gifted genetic scientist, from the planet Bolovax Vik, located in Space Sector 674. Kilowog was trained by Lantern Ermey (reference to Gunnery Sergeant R. Lee Ermey), who would often use the word "poozer", which means "useless rookie" (a word Kilowog would later adopt, albeit in a friendlier way). In the middle of a particularly arduous training session, Ermey had Kilowog and his fellow rookies help stop an attack on a group of Lanterns, one of whom was the future renegade Sinestro. Ermey, fatally wounded in battle, commended Kilowog on his abilities, telling him that he had the makings of a great leader. In addition to serving with distinction as the Green Lantern of that sector, Kilowog also began to spend extensive periods of time on the Green Lantern Corps' home planet of Oa instructing new recruits on how to handle and best utilize their power rings. In this capacity, Kilowog acted as the first trainer to a young Hal Jordan, the ring-recruited successor to the slain Abin Sur of Ungara, the Green Lantern of Space Sector 2814. Kilowog and his new recruit helped the Guardians confront Abin Sur's murderer, the hive mind interstellar malefactor known as Legion.


Crisis
During the Crisis on Infinite Earths (referred to as a "great crisis"), Bolovax Vik was destroyed. This was a powerful blow to the giant Green Lantern, as his race lived a highly communal lifestyle, and to be alone was one of the worst things imaginable. Owing somehow to this genetic similarity to and affinity for each other that all Bolovax Vikians possessed, Kilowog was able to rescue the entire population of his homeworld (billions of beings) by storing their collective life essences within his ring upon that world's annihilation.

The Crisis saw the immortal Guardians ethically divided (a faction of six Guardians broke away from the majority, deciding to follow the example of their estranged brethren The Controllers and create their own Green Lanterns to directly combat the Anti-Monitor, but five of them were killed shortly after they chose their first and only recruit, Guy Gardner of Earth) and their ranks depleted for the first time in millions of years (only 22 of the 36 Guardians survived). The Corps as well suffered hundreds of casualties. The Guardians then decided to end their direct leadership of the Corps, and left for another dimension with their former mates, the Zamarons.


Earth years
Before leaving, the Guardians informed the remaining Green Lanterns that the Corps was now theirs to administer; they were no longer bound by their former assignment to one particular Space Sector and could deploy themselves as they saw fit. Adrift following the destruction of his Sector and the end of his role training new Green Lanterns for the Guardians, Kilowog relocated to Earth with his former pupil Jordan and the group of Green Lanterns that had decided to make their base there. They ultimately became the Green Lantern Corps of Earth. While his appearance at first frightened most humans, Kilowog briefly became a celebrity following his defeat of the villain Black Hand on live television in a battle over Anaheim Stadium.

This goodwill was soon squandered, though, when he was approached by a KGB agent and invited to live in the Union of Soviet Socialist Republics, as the society of Bolovax Vik was somewhat similar to a communist system. During his time in the USSR, Kilowog was instrumental in the creation of the Soviet Union's first super-powered force, the Rocket Red Brigade. Kilowog ultimately became disenchanted with the U.S.S.R. and the flawed communist nations of Earth.

While adventuring with the Green Lantern Corps of Earth, Kilowog found a world in Space Sector 872 which would make a suitable "Bolovax Vik II". Moved to action, he tapped into his ring and reconstituted the entire population of his world, some 16 billion beings. No sooner had he done this, though, than the world was obliterated by the renegade Green Lantern Sinestro, and all 16 billion Bolovax Vikians were permanently killed. The trauma of this drove Kilowog temporarily insane, but he was helped back to his senses by fellow Green Lantern Arisia, to whom he confessed his love. He was also supported by other Green Lanterns, who made an effort to be near him, as they knew Kilowog's race enjoyed being in crowds.

Shortly after this adventure, the Corps was finally and completely destroyed when they voted as a body to execute the captured Sinestro for crimes against the universe; this set in motion a chain of events that led to the dissolution of almost all power rings. Around this time, Kilowog is allowed to be one of the honor guard at Superman's funeral.


Emerald Twilight
When the Corps began to expand again, Kilowog returned to Oa to train the new generation of Green Lanterns. During the Emerald Twilight arc, numerous Green Lanterns were sent to stop the supposedly insane Hal Jordan. The very last Green Lantern to oppose Jordan was Kilowog himself, on Oa. He attempted to prevent his old pupil from entering and absorbing the power of the Great Battery itself, which destroyed the Corps. Kilowog was disintegrated with a blast by Jordan's ring, leaving nothing but a seared skull and ashes, and a shaken but undeterred Jordan stole the energies of the Great Battery. The remaining guardians sacrificed themselves by merging their life forces into the final green lantern ring. The only Guardian left to bestow the ring was Ganthet.



Dark Lantern
The enigmatic being known as Dark Lantern seemed strangely familiar to those closely acquainted with the legacy of the Green Lantern Corps when he first made his presence known on Earth.

He was created by some of the remaining Green Lanterns who had lost their rings when Hal Jordan went mad. Based on Xudar, they called themselves the "Brotherhood of the Cold Flame". Boodikka was one of their number. They tapped into arcane forces and based on the unusual nature of the Bolovax Vik afterlife, they converted the soul of Kilowog into the Dark Lantern in order to send him after Jordan.

When Jordan became the Spectre, he convinced his old friend Tom Kalmaku to help correct his sins against the Green Lantern Corps. Kalmaku used Hal's old power ring to rebuild Oa and the Great Battery as shown in Green Lantern Legacy: The Last Will and Testament of Hal Jordan. This allowed the vengeful spirit of Kilowog to rest. Soon after this, though, his spirit was recalled to life by Kyle Rayner and Ganthet.


The New Corps
Recently the Guardians were reconstituted, and reformed the Corps in the wake of Hal Jordan's rebirth.

Kilowog retakes the role of Green Lantern drill sergeant, training new recruits (or "poozers" as he often refers to them) for the newest incarnation of the Green Lantern Corps, once again in the service of the Guardians of the Universe. In the Infinite Crisis storyline, Kilowog (along with fellow Green Lantern Kyle Rayner, later Ion) played a key role in the Rann-Thanagar War and its aftermath.

In Superman/Batman #30 (2007) Kilowog is deeply affected by a force that has turned most of the super-powered aliens allied with Earth hostile against all humans. He, or the force controlling him, attempts to violently sway Superman into hating all humans, but a very confused Man of Steel does not fall for it. It is later revealed that Kilowog and other alien heroes are being affected by Despero and an alien armada. The threat is swiftly neutralized by Superman and Batman.

Once again, in Green Lantern Corps #11 (2007) Kilowog is pushed, apparently from a Despotellis-infected Mogo, into a xenophobic hate against the Guardians and the Corps, acting with imagery of his dead people. Kilowog fell victim to the deception.

During the Sinestro Corps War, Kilowog was on the front line during the battle of Mogo. When the conflict moved to Earth, Kilowog battled his Sinestro Corps counterpart, Arkillo. Kilowog defeated the villain and removed his ring. After the war's climax, Kilowog was seen on Mogo, eating dinner with energy constructs of his family members.


Blackest Night
During the Blackest Night event, Oa is invaded by a swarm of black power rings, that turn all the deceased Lanterns in the Oan crypt into Black Lanterns, who promptly attack the living Lanterns. Kilowog is attacked by the reanimated Ermey, who mercilessy berates him for not preventing his death, and for saving the life of Sinestro, citing the deaths Sinestro had caused as being Kilowog's fault. He also torments Kilowog over the death of the current class of Green Lantern rookies, whom Ermey himself had just slain. Gaining the upper hand, Ermey attempts to rip out Kilowog's heart, but is interrupted by the announcement that Black Lanterns' rings have reached one hundred percent power. Subsequently, the Black Lanterns are given new instructions: to devour the Central Power Battery. Ermey departs for his new objective, joined by the rookie Lanterns he had just killed. Kilowog then joined his fellow Green Lanterns in their attempt to protect the Central Power Battery.


War of the Green Lanterns
Kilowog and Arissa accompany Guy Gardner on a mission to the 'unexplored sectors'. The three defeat a powerful telepath. They also avenge the death of several Lanterns, a concept Kilowog is becoming increasingly unable to process.

When Krona launches his attack on the Green Lantern Corps by infecting the power battery with Parallax, Kilowog is the only alien Lantern not to fall under Krona's influence due to his past experience with the entity. However, Krona quickly deduces the reasons for his greater resistance, forcibly placing a new ring on Kilowog's finger to bring him under his control.

Following the war, Kilowog briefly attempts to resign from the Corps after the Guardians discharge Hal Jordan and allow Sinestro to at least provisionally remain a Lantern, but is convinced to rethink his decision by Salaak due to the obvious upheaval the Corps will have to undergo in future due to the destruction of Mogo. Kilowog instead retires from his duties as a drill instructor, which is taken over by the robotic GL 'Stel'.


The New 52
Kilowog is back to being drill instructor of the Green Lantern Corps, and is part of the team that breaks John Stewart out of prison when the Alpha Lanterns sentence him to death. He and Salaak have also uncovered the Guardians' plans regarding the Third Army. Later when the Guardians attempt to lure their Green Lantern members to Oa under a fake inoculation treatment for the Third Army so they would be assimilated into it, Kilowog by then had secretly contacted trusted members within the corps and assembled them into a small army to face the Guardians. By having the now powerless Guy Gardner serve as a distraction, Kilowog used the opportunity to seize control of the Central Power Battery and not only freed the Lantern members the Guardians immobilized, but also ended the communication blackout allowing him to warn the approaching members of the Guardians deceit.

Kilowog stays with the Lanterns through the destruction and overthrow of the Guardians. He accepts the leadership of Hal Jordan. Despite knowing use of the lantern power endangers the universe, Kilowog volunteers to fight back when the actions of the 'New Gods' endangers all ring wielders.
