In fearful day, in raging night,
With strong hearts full, our souls ignite,
When all seems lost in the War of Light,
Look to the stars-- For hope burns bright!
The Blue Lantern Corps was founded by Ganthet and Sayd. two former Guardians of the Universe. For daring to acknowledge the Blackest Night Prophecy, they were banished from Oa. After their exile Ganthet and Sayd settled on the planet Odym to create the first Blue Power Ring, and eventually the Blue Lantern Corps itself.
The Blue Lantern Corps were created by Geoff Johns and Ethan Van Sciver and first appeared in Green Lantern # 25.
Ganthet and Sayd started the Blue Lantern Corps, and was then joined by Saint Walker, chosen by Ganthet and Sayd. Protocol in the Blue Lantern Corps has the newest member select the next candidate for the corps. So Saint Walker chose Brother Warth who in turn chose Brother Hymn. Brother Hymn selected Sister Sercy to join, Sister Sercy being the newest member will select the next person to join the Blue Lantern Corps.
Recently, after Blackest Night, Ganthet and Sayd are no longer guardians to the Blue Light of Hope, with Ganthet becoming the GL of Sector 0 where Oa is located, and Sayd enslaved to Larfleeze as the Guardian of the Orange Lantern Corps.

Rage of the Red Lanterns
For more information see: Rage of the Red Lanterns
Appearing just in time to save the Green Lanterns from the ambushing Red Lanterns, the first Blue Lantern reveals himself. Saint Walker, Blue Lantern of Sector One rescues Hal Jordan using his Blue Power Ring, and heals Jordan's wounds before leading him to Odym, home to the Blue Lantern Power Battery. On the way there Hal notices that his ring is functioning at 200% capacity simply from being in close proximity to Walker, revealing another aspect of the Blue Rings. Upon arriving, Hal is introduced to the second Blue Lantern inductee, Brother Warth, and brought before Ganthet and Sayd. They ask Jordan to go with Walker and Warth to rescue Sinestro from the clutches of Red Lanterns, saying that the universe needs him if it is to survive the imminent War of Light.
Hal grudgingly agrees, and leaves with Warth and Walker for Ysmault, home of the Red Lanterns. During their journey, Walker tries to convince Hal of the limitations he faces as a Green Lantern, stating that Hal should join the Blue Lantern Corps as their leader. Jordan is dismissive of these claims however, saying he has no interest in leaving his Corps. Walker, it seems has other plans, telling Warth that they need to make Jordan a Blue Lantern. Upon their arrival, Hal finds Sinestro being held captive, but is immediately ambushed by Atrocitus and his Red Lanterns. The Sinestro Corps appear to free their leader, turning the small skirmish into a planet-wide battle. Using the Blue Light of Hope to extinguish the Red Fire of Rage, Warth and Walker join the fray.
In the midst of battle Hal finds Laira, a former Green Lantern thought to be lost to Parallax, and an old friend. Horrified to discover she has become a Red Lantern, Hal tries desperately to reason with her, and convince her to abandon her ring. Sinestro, losing patience with Hal's compassion takes matters into his own hands, using his own ring to kill Laira, blasting her through the chest. Hal, already bearing strong hatred for Sinestro, is pushed over the edge by Laira's death and loses himself to the Red Light of Rage. Hal's anger is so great that Laira's Red Power Ring chooses him as her successor. Atrocitus, founder and leader of the Red Lanterns Corps arrives, welcoming him into the ranks of the Red Lanterns. Hal's transformation leaves Warth and Walker powerless, revealing the inherent weakness in the Blue Lantern Corps. A Blue Power Ring is rendered nearly powerless without an an active member of the Green Lantern Corps in the immediate vicinity, as willpower is required to make hope into reality.
Knowing Jordan's only chance to escape his all-consuming rage rested with the Blue Light of Hope, Walker puts his own Blue Power Ring on Hal's hand. With a great flash, Hal's Red ring is destroyed by the healing light of Hope, and Hal himself is purged of it's burning corruption. Hal Jordan, the greatest Green Lantern, becomes the Universe's first Composite Lantern, a vessel of both Hope and Will. Now wielding the powers of both the Blue and Green Lantern Corps Hal makes short work of the Red Lanterns, allowing the Sinestro Corps to escape with their leader.
Despite having lead to his rescue, Hal is extremely angry with Walker for forcibly inducting him into the Blue Lantern Corps, saying he has "no interest in Hope". Walker meanwhile seems frustrated at Hal's refusal to accept his new ring, and his inability to acknowledge the Power of Hope. Trying and failing to remove the Blue Ring themselves, Hal, Warth, and Walker return to Odym seek out Ganthet and Sayd. To Hal's dismay, neither of the former Guardians can remove the ring. Seeing no reason to remain on Odym Hal decides to leave the planet. Just before departing Sayd reveals that the ring cannot be removed, and that it would only leave Hal after finding what he hopes for. Walker,expressing his concern at Hal's indifference to the Blue Light, is put at ease by Ganthet, saying that Hal would come to recognize the power of Hope, but as a Green Lantern. After Hal's departure, Sayd expresses the urgency of Walker's need for a new ring, and Ganthet explains the new tasks that lie before them. Warth and Walker are sent out to find new recruits to expand the Corps and to search for the Indigo Light of Compassion, for Hope and Compassion must work together.

Later, Hal meets Agent Orange who controls the Orange Light of Avarice. Larfleeze, aka Agent Orange, notices Hal's blue ring and states his desire for it. Hal explains he is unable to remove it and so Larfleeze chops off Hal's hand with the ring. This is later revealed to be an illusion created by the ring. Hal battles Larfleeze and the Blue Ring keeps asking him what he hopes for. Hal tells it that it hopes for it to stop asking him that question.
The ring recognizes sincerity in the Green Lantern's voice and fully charges all the rings of the nearby Green Lantern Corps. After sufficiently weakening Agent Orange, the ring releases itself from Jordan's hand and promptly leaves to find a worthy successor from Hal Jordan's home sector of 2814. The Guardians realize they have to settle everything with Larfleeze so they dismiss the Green Lantern Corps and open negotiations with Agent Orange.
Once it is done, Hal asked what Larfleeze wanted, but the Guardians replied it doesn't concern him. Larfleeze wanted to know the location of the Blue Lanterns and the Guardians reveal it to him, there base is Odym. Larfleeze takes his Orange Lantern Corps to Odym and confronts the whole of the Blue Lantern Corps which is merely Ganthet, Sayd, Saint Walker, Warth, and the two newest members, Brother Hymn and Sister Sercy.
For more information see: Blackest Night
During the Blue Lanterns' struggle against Larfleeze, a number of black power rings come to Odym. Unable to detect any dead bodies on the planet's surface to attach themselves to, the rings hovered in the sky, waiting for a death to occur. The battle goes the way of the Orange Lanterns until Hal Jordan arrived on the planet. Under the influence of Jordan's green power ring, the Blue Lanterns' rings are charged by Jordan's willpower and capable of combating Larfleeze's constructs. The constructs suddenly disappear as Larfleeze finds himself being attacked by the reanimated corpses of his Orange Lanterns, now members of the Black Lantern Corps.
Jordan, Sinestro, Carol Ferris, and Indigo arrived on Odym during the conflict in order to recruit Saint Walker to help form a white light composed of the seven lights of the emotional spectrum that will defeat the Black Lantern Corps.
Saint Walker, Ganthet, and Sayd join the team Jordan and Indigo have assembled, and accompanied them to recruit Larfleeze and Atrocitus. Despite saving him from the Black Lanterns, Larfleeze resisted to join the group due to the nature of his power and an interest in obtaining his own Guardian. In order to secure his participation, Sayd offered him her servitude in return for his compliance. Atrocitus was also unwilling to assist the team, attacking Jordan and Sinestro in his rage. To calm Atrocitus, Saint Walker showed him an illusion where he and a female of his species are happily being invited to the Blue Lantern Corps. When the illusion proves insufficient, Saint Walker convinced the Red Lantern to join them by relating the story of how his family died in an effort to save his world. Atrocitus joined the group, and they headed off to Earth.
While on Earth, and awaiting for Corps back-up, Ganthet activated a ring fail-safe to find nearby Deputy Lanterns. Ganthet was inducted into the Green Lantern Corps while Barry Allen became a Deputy Blue Lantern.
Post-Blackest Night, Saint Walker is seen blessing desecrated tombstones while Ganthet and Sayd are no longer guardians of the blue light.
In the DCnU, Blue Lanterns are a part of the New Guardians series, with Ganthet being emotionally stripped by the other guardians. They have also appeared in the Bue Beetle series.
The Blue Lantern Power Rings
The Blue Power Rings are unique amongst those of the other corps. Simply being in the presence of an active Blue Lantern is enough to charge Green Power Rings to 210.5% capacity, or possibly higher, so long as the Blue Lantern "Hopes for their well being" . The Blue Light of Hope also seems to be the only way to extinguishing the Red Flames of Rage used by the Red Lanterns. Unlike those of the other Corps, the light constructs produced by a Blue Power Ring are created based off of the emotional and psychological state of their target, as opposed to what the wielder can imagine. The Blue Light of Hope has also been shown capable of great feats of healing and restoration, even to the extent of rejuvenating a dying sun, and giving new life to other Power Rings. As the Blue Power Rings draw their power from the collective Hope of the Universe, they have no need to re-charge using a Power Battery.
Placing a Blue Power Ring on a Red Lantern's finger is the only known way to remove a Red Power Ring from its host without killing them, due to the fact that a Red Lantern's Ring essentially replaces their heart, and its removal through any other means would prove fatal. If however, the Red Lantern is also a member of another Corps, the introduction of the Blue Power Ring has the added effect of turning its new host into a "Composite Lantern". The Composite Lantern, now wielding both their original Power Ring in addition to their Blue one, becomes a hybrid vessel for both their original power and those of the Blue Lanterns. The only known example of this phenomenon occurred when Saint Walker gave Hal Jordan his ring in order to save him from the Red Light of Rage. While unable to remove the Blue Power Ring himself, it came off of its own accord when Hal achieved "What he hopes for".
The Blue Light of Hope has but one weakness, one that Atrocitus is also aware of. Hope is useless without the Willpower to enact it, and, as such, without an active member of the Green Lantern Corps nearby, a Blue Power Ring is rendered nearly powerless, left only with the powers common to all Lantern Corps members.
Blue Lantern Corps Recruitment
The Blue Lantern Corps have a very unique recruitment process. Each Blue Lantern is chosen by the Blue Lantern of the preceding sector and brought before Ganthet and Sayd, to be evaluated. The evaluation consists passing on the teachings of the Corps, judging the initiate's character, and training the new recruit in all that they need know to spread the Blue Light of Hope. If, after three days they are deemed worthy the candidate is then inducted into the Blue Lantern Corps and begins the search anew for the next Blue Lantern.
Many members of the Blue Lantern Corps are tend to recite the saying, "All will be well."
