Fictional character biography 
Ganthet is one of the Guardians of the Universe. However, where most of the Guardians are very stern 'by-the-book' characters, Ganthet has a personality that is more human-like, including displays of empathy, kindness and concern for an individual, instead of only thinking of the Green Lantern Corps. In various DC crossover limited series such as Kingdom Come, Ganthet is shown as being part of the Quintessence, a group of gods who oversee the universe (or multiverse) in its entirety, although they seem to focus on Earth.
Although he has been portrayed as looking like the other Guardians, Ganthet is often distinguished by tying his hair into a long ponytail, as the other male Guardians have shorter, unkempt hair.
Green Lantern: Secret Origin 
In the Green Lantern: Secret Origin story, Ganthet (without ever revealing himself physically) asks Sinestro to investigate the death of Abin Sur (through non-official channel, bypassing protocol), thus leading to Sinestro's first meeting with Hal Jordan, happening in Earth.
Ganthet's Tale 
The graphic novel Ganthet's Tale by John Byrne from a story by Larry Niven tells the story of Hal Jordan's first encounters with Ganthet. Jordan is asked to help Ganthet battle a renegade Guardian, Dawlakispokpok (or Dawly, for short) who is trying to use a time machine to change history. In the early era of the planet Oa, a scientist named Krona attempted to use a time machine to see the beginning of time. In using his time machine, Krona somehow 'bled' the universe of a billion years of life. Dawly is going to use his own time machine to thrust Krona to the end of time, preventing him from following through on his plan. In battling Dawly, however, it turns out that Dawly is responsible for the mishap that caused the universe to be 'born old'. When Dawly's family is brought before the Guardians, Ganthet shields Jordan's mind, allowing him to retain his memory of one of the biggest secrets of the Guardians.
Emerald Twilight 
After the destruction of Coast City (in the "Reign of the Supermen" storyline), the subsequent "insanity" of Hal Jordan, and the destruction of the Main Power Battery, the Guardians decide to focus all of their remaining power into Ganthet, recognising that he was the only one of them to foresee a catastrophe like Hal Jordan's current attack on them. As such, he becomes the last Guardian. Ganthet creates a new Green Lantern ring from Jordan's ring (which was crushed by the former Green Lantern after murdering Sinestro) and goes to Earth. He appears before Kyle Rayner and hastily hands him the ring, muttering "You shall have to do".
Guy Gardner later claimed that Ganthet first went to him but Gardner turned him down. During Rayner's first few months as Green Lantern, Ganthet is less than satisfied with Rayner and attempts to take back the ring. Rayner eventually earns the respect of Ganthet by facing Parallax without his ring.
The Quintessence 
Ion and the new Guardians 
When Rayner briefly became the godlike Ion, he possessed more power than Hal Jordan did as Parallax. Realizing that he could not continue as Ion without losing his humanity, Kyle traveled to the recently restored Oa to recharge the Central Power Battery. By doing so, he created a new set of Guardians, this time as small children (both male and female), with the intent that Ganthet, as their "father figure," will look after them and teach them how to be better Guardians than their predecessors[volume & issue needed]. After one of the children, Lianna, went missing and was later revealed to have aged prematurely, Ganthet invited the Zamarons to Oa to help raise them with him.[volume & issue needed]
When the Martian Manhunter reverted back to the 'Burning Martian' identity that the Guardians of the Universe had locked away long ago and attacked the Justice League, Ganthet teleported John Stewart to safety and treated his injuries when the rest of the League teleported to the Fortress of Solitude to escape the Burning's initial attack. Ganthet was later able to tell John the history of the Burning Martians and teach him a way to 'reroute' his mind to think in the first language of the universe so that he could rescue his teammates from Fernus in a hit-and-run attack (Although the intensity of this method of thought meant that John could not use it for more than sixty seconds without burning his mind out), allowing them to come up with a plan to defeat Fernus.
Green Lantern: Rebirth 
Ganthet played a crucial role of resurrecting Hal Jordan, who was revealed to be possessed by the fear entity Parallax during Green Lantern: Rebirth. Following the return of Hal Jordan, all the Guardians are aged to adulthood and are just as cold and manipulative as before. The only change is that there are now female Guardians as well as male. Ganthet, of course still retains a sense of individuality amongst the Guardians, believing that they should retain their emotions; Sayd is the only other Guardian who shares his mindset.[volume & issue needed]
Sinestro Corps War 
Just as Parallax (freed from any hosts) attacks the Lanterns for freeing Kyle Rayner, Ganthet and Sayd arrive and draw Parallax into four separate lanterns (Hal, Kyle, John, and Guy's, respectively), reasoning that the Earth Lanterns had proven their superior ability to overcome fear and the division would prevent anyone being able to release Parallax again. As Ganthet explains, he and Sayd were kicked out of the Guardians of the Universe. Ganthet's final act as Guardian is offering Kyle his power ring. He asks if Kyle is willing to downgrade himself to a normal Green Lantern, which Kyle quickly accepts. The four men then take their lanterns and hearing the Sinestro Corps oath, recite the Classic Green Lantern Oath, and depart to confront Sinestro's Corps.
Ganthet and Sayd also explain to the four about the emotional spectrum created at the start of the universe that is separated into seven colors: green (willpower), yellow (fear), violet (love), red (rage), indigo (compassion), orange (greed), and blue (hope), each representing different forms of emotion, with green being the most center balanced of the energies. The further at one end an energy color is, the more wild its power is to control, leading to the energy corrupting its user. Ganthet also reveals that in the coming future, each color will have its own forces like the Lantern Corps, and these forces will fight against the others in a battle across the universe that will lead into the event known as "The Blackest Night", the worst of the hidden prophecies of the Book of Oa.
Blackest Night 
At the end of the Sinestro Corps War, Ganthet and Sayd are currently living on the planet Odym, where they harness the blue energy of hope and make plans to create another intergalactic police force in order to aid the Guardians and the Green Lantern Corps of their upcoming battle against "The Blackest Night" by creating blue power rings and batteries. The first of the Blue Lanterns is an alien named Saint Bro'Dee Walker or Saint Walker. The second is Warth, an elephant like alien from Sector Two. According to Saint Walker, Warth will select another candidate from a different sector of space and the process will continue from there. Later, Ganthet reveals to the Blue Lantern Corps that he and Sayd are planning to create an alliance to those who wield the indigo power of compassion along with Oa. However, Ganthet, Sayd, and the Blue Lanterns find themselves being attacked by Agent Orange as the villain seeks the powers they possess. They were eventually rescued by Hal Jordan, accompanied with Sinestro, Carol Ferris, and Indigo Tribe member Indigo-1.
Ganthet and Sayd then seek Atrocitus and Larfleeze's aid to recreate the "white light of creation" with their saviors. In order to get Larfleeze to cooperate with them, Sayd offers her servitude to Agent Orange, who expresses desire of having his own Guardian, over Ganthet's protests. Ganthet and Sayd later arrive at Coast City with the Lanterns to aid Earth's heroes and trying to free the Guardians from the Black Central Battery. Failing that, Ganthet duplicates Hal Jordan's ring and places it on his own finger, inducting himself into the Green Lantern Corps. He and Sayd also duplicate the other Lantern Rings, allowing the other six corps to gain temporary 'deputies' to fight alongside the seven already present until the rest of the Corps can arrive. As a result, Lex Luthor becomes an Orange Lantern, Wonder Woman- after being freed from the influence of her Black Lantern ring- becomes a Star Sapphire, Barry Allen becomes a Blue Lantern, Ray Palmer becomes an Indigo Tribesman, Mera becomes a Red Lantern, and Scarecrow becomes a Sinestro Corps officer.
Brightest Day 
After the Blackest Night is over, Ganthet is seen plotting with Atrocitus and Guy Gardner a new, universe-saving plan against a new, hidden foe. To further advance his new cause, Ganthet renounces his Guardian status, requesting his fellow Oans to fill in the permanent post of Green Lantern of Sector 0, forging his own lantern and power ring in the process. Notably, his new Power Battery lacks the ordinary, rounder design, and looks much similar to the squared, older ones once wielded by the Manhunters and the Halla's. He was later forced to assist Hank Henshaw, who has learned from the hidden foe that Ganthet is apparently the key to Henshaw's permanent death. By threatening to make the Alpha Lanterns kill themselves if Ganthet does not cooperate, Henshaw made Ganthet operate several Alpha Lanterns to try and restore them to organic life-forms, believing that the process, once perfected, can be used to return him to a mortal body. During the process some Alpha Lanterns perished but Ganthet eventually manages to imprint in the Alpha Lanterns insights, values and priorities and gave them a semblance of free will but could not restore their organic life-forms. Henshaw got interference by several Lanterns who come to the rescue and Ganthet turns on him, eventually destroying Henshaw's cyborg body, while his astral form is destroyed by Alpha Lantern Boodikka in the mental plane when he attempted to hide in her Alpha Power Battery. Afterward, all the Alpha Lanterns have their free will restored, thanks to Ganthet.
Ganthet brings up more blood, which transforms into Atrocitus' head, who reveals their alliance. Ganthet is forced to admit to his fellow Lanterns that a short time ago that formed into a tapestry of future events, and that, having learned that Atrocitus had the same thing happen to him, he and Guy entered into their alliance.
War of the Green Lanterns 
With Krona having returned Parallax to the Green Lantern power battery and infecting the other six remaining Guardians with the other emotional entities, Ganthet, Kilowog, and the four Earth-based Green Lanterns are the only ones even partly immune to Parallax's influence due to their prior experience under his influence, but he is still forced to take Kyle and John's rings when they are driven to attack each other. Unfortunately, when Ganthet takes their rings and his own, the three rings explode, destroying his hand, forcing John to bandage the amputated limb. With the other Green Lanterns searching for them, Ganthet orders John and Kyle to depart while he uses his own Guardian-based powers to draw the Lanterns away.
Despite the odds against them, the four Earth Lanterns were able to rescue Ganthet from Krona using the rings of the other six Corps: Hal wielding Sinestro's ring, John Indigo-1's, Kyle Saint Walker's and Guy Atrocitus, Ganthet later advising Hal and Guy to use Larfleeze and Carol's rings respectively to remove Parallax from the Central Power Battery to free the other Green Lanterns from his influence. Ganthet was also able to help Guy master both of his rings by encouraging him to tap into something that he loved and something that he hated. Afterward, Ganthet is visited by Saint Walker, who restores his hand. His blue ring shows Ganthet an image of Sayd, revealing that he still misses her.
The New 52 
Following the War of the Green Lanterns storyline, to compensate for the new shortage of Guardians, the other Guardians strip Ganthet of his emotions so that he will rejoin their ranks. Kyle Rayner comes to Oa for help after something has turned him into a 'ring magnet', causing rings from the other six Corps to try and latch on to him. Kyle likens Ganthet's transformation to a lobotomy, though Ganthet himself disputes this because "my cognitive abilities are unimpaired." Kyle then compares the process to taking away Ganthet's soul, as he is now nothing more than another Guardian: a charge to which Ganthet does not respond. After Kyle is briefly overwhelmed by the other rings he wields, Kyle's green ring throws Ganthet aside when he attempts to remove it. As the other Lanterns attempt to help Kyle, Saint Walker appeals to Ganthet for help, but Ganthet simply throws Walker off, now regarding the Blue Lantern Corps as a mistake that must be rectified. Ganthet's dismissive attitude towards his past remains even when Sayd is revealed to be accompanying Larfleeze's attack, although he appears to retain a degree of affection for Kyle, as he offers Kyle a chance to return to the Green Lantern Corps if he agrees to remain on Oa so that the consequences of his temporary period wielding the other six rings can be studied. However, hearing Sayd tell him that the Ganthet they knew will be gone forever if Kyle goes with him now, Kyle rejects Ganthet and escapes with the other ring-wielders, stating that, while he may consider Ganthet a father, he has to do things his way.
It is later revealed that Ganthet told the other Guardians that during his time as a Green Lantern, he found the Corps, like the Manhunters, has serious flaws because of the disobedience of Green Lanterns like Hal Jordan or Sinestro, and announces that it is time to replace the Green Lantern Corps with the "Third Army". Although the 'New Guardians' go their separate ways when it is revealed that Sayd brought them together by drawing rings from weaker wielders to Kyle Rayner due to his connection to Ganthet, Kyle is apparently still trying to recruit other ring-wielders together in an attempt to rescue Ganthet and restore him to what he was, even as Ganthet himself states that he considers the Guardians as having 'saved' him rather than the other way around.
Ganthet arrives on Zamaron to attack Kyle. He nearly kills him with his blasts, while the Third Army invades the Zamaron homeworld, but the injured Kyle transforms into the White Lantern, having mastered the seven powers of the emotional spectrum due to his refusal to give up on Ganthet helping him master the violet power of love. When Ganthet witnesses Kyle being able to destroy the Third Army, he becomes fearful and flees, while the group will apparently be able to stop the Guardians' threat.
When Volthoom is freed, Ganthet finds himself imprisoned on the planet Maltus by Volthoom, who then restores Ganthet's emotions and to his original state before the Guardians stripped him of his emotions. Ganthet comes to feel shame for his actions and for his battle with Kyle. In the final battle, the Guardians are finally freed when Volthoom is destroyed, but they are then executed by Sinestro. Sinestro spares Ganthet and reunites him with Sayd (who has survived the Third Army attack), but exiles them both from Oa.
