Blue Lantern Corps (Justice League/Teen Titans)

"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!"

- Superman quoting the Blue Lantern Corps' Oath The Blue Lantern Corps is a organization of alien superheroes similar to the Green Lantern Corps. Their powers, similar to those of other organizations based around the emotional spectrum, are fueled by the emotion of hope. This version is formed by Superman with the aid of Ganthet and the Corps' guardian entity of Hope Adara.

Superman / Clark Kent / Kal-El
The Corps' core Leader (commonly addressed as the Grandmaster of the Blue Lantern Corps) and founder. He formed the Corps after overhearing the story of Adara, the embodiment of Hope. Later, when his cousin Kara became a member of the Red Lantern Corps, Superman was recruited by Ganthet in the search for Adara. Freed, Adara forged the Blue Lantern Power Battery, passing the first Ring to Superman. In his first mission as a Blue Lantern, Superman helped the Green Lanterns win the War of Light by freeing his cousin from her Red Lantern influence (the progress alos shared his memories with Kara, confirming that he really was his cousin, who survived the destruction of Krypton just the same way she did).

Ganthet
One of the Guardians of Oa. He was the co-fonder of the Corps.

Adara
The Corps' Bird-based Guardian Entity.

Saint Walker
The Corps' Second-in Command, a Blue Lantern of Sector 1 and the second Blue Lantern to receive his ring. Whenever Superman is absent, Saint Walker assumes leadership in the Corps.

Brother Warth
A wise Blue Lantern of Sector 2. He was the third Blue Lantern to receive his ring. He is an elephant-like alien who bears a strong resemblance to the Hindu god Ganesha.

Mala
An Amazon of Themyscira who is one of Wonder Woman's closest friends and companions and is a Blue Lantern of Sector 666. She was the fourth member to receive her ring as well as the Corps' first female Blue Lantern. She was chosen by a Blue Lantern Ring after she gave children of Metropolis Hope when they were scared by the presence of Apokolips' Furies.

Arisia Rrab
A young Graxosian Blue Lantern of Sector 2815. She is Superman's personal Blue Lantern prodigy. She was once a dedicated Green Lantern rookie until she overheard an argument between Kilowog and Kentor Omoto (who infamously called her and everyone of the other rookies as a "Troq" (a term which meant a "Nothing", a worthless person)) and eventually quit. She was later comforted by Laira and Superman, who convinced her not to lose hope and recruited her in the Blue Lantern Corps to overcome her inner doubts and shame.

Solovar
The former king of Gorilla City on Earth until he was overthrown by Gorilla Grodd, Solovar became a Blue Lantern of Sector 666 when he helped some humans escape the Ape Tyrant's clutches. Most currently, Solovar is Superman's adviser.

Oreo the Hawk
A formerly domesticated hawk of Earth who became a Blue Lantern of Sector 1014 after he inspired his deceased owner's family in not quitting or losing Hope.

Collin Hill
An 9-year old Orphan who lost his parents after Vandal Savage's ruthless murder of Ronnie Raymond (Martin Stein's first merging partner as Firestorm) and was abandonned by his ruthless older half-brother. He became a Blue Lantern of Sector 2814 after Adara (in the form of a peacock) gave him a Blue Lantern ring to help him overcover grief and solitude. He is also a member of Terra's Knights of Rao.

Starfire / Koriand'r
The Princess of Tamaran and a founding member of the Teen Titans. Starfire joined the Corps after she felt ashamed of her current look (which only happened to be caused by an unknown alergy) until she was comforted by Superman. Later, she was recruited by Adara as a Blue Lantern when the entity sensed not only Starfire's need for Hope, but also her past actions which brought about Hope on Earth's humans. Starfire was eventually restored to her normal looks when the ring attached to her. Her activity in the Corps is similar to Superman's; while she still chooses to be with the Titans, she still keeps her ring just in case she needs it.
