Bro'dee Walker is a priest living on the planet of Astonia with a wife and two children. Astonia is doomed, as its ancient sun is dying. Walker manages to calm his despairing people and give them hope in the face of extinction. A power ring chooses him to become a member of the
Blue Lantern Corps, stating that he "has the ability to instill great hope". With his ring, Walker sets his sun's age back 8.9 billion years, thereby saving Astonia. Saint Walker and his fellow Blue Lanterns are introduced during the
Final Crisis event as part of the build-up to the
Blackest Night storyline. During the Final Crisis,
Hal Jordan and
John Stewart of the
Green Lantern Corps are ambushed by the
Red Lantern Corps, who take the rogue former Green Lantern
Sinestro from their custody. Jordan is injured during the conflict, and his wounds are healed when he first comes into contact with Saint Walker. In the
Blackest Night storyline, having joined Hal Jordan's and Indigo-1's efforts to rally one member of each Corps to attempt to destroy the
Black Lantern power battery, Saint Walker agrees to use his power ring to ease
Larfleeze's hunger while they work together. When deputizing an Earth hero to assist in the current crisis until the rest of the Blue Lantern Corps can arrive, Walker's ring selects
Barry Allen as a temporary Blue Lantern. After
Nekron is defeated, Walker works with
Carol Ferris to heal
Mera of the influence of her
red power ring. In
Justice League of America (vol. 2) #55 (2011), Saint Walker joins the titular team in battling
Eclipso and attempts to assist the resurrected
Hank Henshaw against
Doomsday on
Batman's orders. In the
War of the Green Lanterns storyline, Saint Walker and the rest of the New Guardians make their way to the planet Ryut.
Krona and the emotional entities are nowhere to be found but the group does come upon the Book of the Black. When former
Sinestro Corps member
Lyssa Drak appears, she quickly subdues the New Guardians, trapping all but Hal in the Book of the Black. Hal escapes with the rings of the New Guardians, later passing Walker's ring on to
Kyle Rayner when Krona infects the Central Power Battery with
Parallax to bring the Green Lantern Corps under his influence. In the final battle, Walker is freed from the book by Kyle. His blue ring returns to him and the Guardians of the Universe return him to Odym.
The New 52 In the series
Green Lantern: New Guardians, Saint Walker assists Kyle Rayner when he becomes a "magnet" for other power rings, helping Kyle escape the attacks of the other four Corps members who have tracked the rings. They travel to Oa to try to seek the aid of the Guardians. This plan backfires when it is revealed that Ganthet has been stripped of his emotions by the other Guardians, to the extent that he attacks Walker when Walker tries to help Kyle directly after he is briefly overwhelmed by the rings. Ganthet proclaims that the Blue Lantern Corps was a mistake that he will now rectify. After being forced to escape the Guardians, Walker heals
Arkillo's severed tongue using an illusion of Sinestro. In the subsequent confrontation with Archangel Invictus, Walker is unable to heal Invictus' anger at the Lanterns, although his actions help Invictus see that the Lanterns are not completely tainted. Returning to Odym to regroup after Invictus releases the New Guardians only if they agree to kill Larfleeze, Walker learns that Odym is being attacked by the
Reach, forcing him to call the other New Guardians for help when he attempts to teach the other Blue Lanterns how to channel their auras to increase their offensive capabilities so that they can fight on their own. Although he and the other New Guardians aid Kyle against Invictus, the team splits up after learning that
Sayd was responsible for drawing the rings to Kyle as part of a plan to assemble a team to save Ganthet, feeling that her actions have tainted the team before it began, regardless of her motives in bringing them together. Following the defeat of the Third Army and the fall of the Guardians, the Blue Lantern Corps relocate to the planet Elpis. They are soon attacked by the cosmic entity Relic, who seeks to rid the universe of its "lightsmiths", considering it the only way to keep the universe safe. The rest of the Blue Lantern Corps are destroyed, with Walker being taken to safety by Kyle Rayner, Carol Ferris and the Templar Guardians. Although Walker recovers, his ring abandons him after he learns that the emotional spectrum is being depleted. Walker regains his hope and his ring after witnessing Kyle Rayner's
White Lantern abilities on
New Genesis, confident that the emotional reservoir can be refilled.
