Green Lanterns, willpower

Main article: Red Lantern Corps
Laira's red power ring.

The Red Lanterns are first mentioned in Booster Gold (vol. 2) #2 in a note written on
Rip Hunter's chalkboard that reads "Beware the Red Lanterns???". In issue #10 of the
same title, another note appears that reads "RED LANTERNS = BLOOD." Atrocitus, a member
of the Empire of Tears on the prison planet Ysmault, forges the first Red Power Battery
from the innards of Qull, the being who told Abin Sur the prophecy of "the Blackest Night".
Laira, one of the "Lost Lanterns", was recruited into the Red Lantern Corps after her
expulsion from the Green Lanterns. However, she was ultimately killed by Sinestro, just
as she began to break free from the Red Lantern ring's control over her.

A red ring feeds on the rage of its user and anyone nearby, and is charged by the blood
of those the user kills.
Contrary to Green Lantern rings, which provide helpful commentary, red rings are depicted
as constantly emitting violent commands ("Kill," "Rage," "Pain," "Hatred," etc.), driving
their wearers insane with rage and reducing them to little more than snarling beasts.[34]
However, Saint Walker states that the rings are deliberately set to select beings with
uncontrollable rage. The energy of red rings replaces the user's blood, which can then
be regurgitated through the bearer's mouth in a highly corrosive form. The red ring's
energy is also capable of corrupting the energies of other power rings, preventing them
from functioning properly.[26] The aura of a red ring is savage and rough in comparison
to a green ring. The Blue Lanterns' energy is the only known power source capable of
neutralizing the Red Lanterns' influences, and in combination with the Green Lanterns'
energy can destroy the red ring.

Some of Larfleeze's orange power rings.

An orange ring is powered by avarice.
According to Ganthet, "the orange light of avarice will be discovered and manipulated by
a being whose greed knows no bounds." Unlike the other Corps, Larfleeze (primarily known
as "Agent Orange") is the only individual to wield the power of the orange light.
The story of how he came to be the sole owner of the orange power battery is detailed in
the Agent Orange story-arc running from Green Lantern (vol. 4) #39-42 (April-July 2009).
The Guardians of the Universe are described as making an agreement with Larfleeze long ago
in return for a box containing the fear entity: Parallax. The agreement allows him exclusive
control of the orange light with the condition that he remain in the Vega system. During
the Agent Orange arc, Larfleeze attracts the attention of the Guardians again through an
act of terrorism prompted by an intrusion from the Controllers on his home planet, Okaara.
 A Green Lantern force confronts him, and (after being unable to decide between releasing
 him and destroying him) create another deal with him at the expense of the Blue Lanterns.

Even alone, Larfleeze is a formidable opponent for the Green Lantern Corps. The power of
the orange light allows Larfleeze to steal the identities of those he kills, transforming
them into an Orange Lantern construct.[38] By being in constant contact with his main power
battery, Larfleeze has become one with his power source. This allows him to maintain a power
level high enough to support an entire Corps of orange light constructs even when separated
from it.[39] Larfleeze and his constructs are shown to be resistant to magic and the abilities
of green power rings, but do not retain the same protection against blue or violet

Main articles: Sinestro and Sinestro Corps
A yellow power ring escaping confinement on Oa.

The first yellow ring was acquired by Sinestro following his banishment to the anti-matter
universe of Qward, and could only be recharged by fighting a Green Lantern. Years later, after
losing the ring to Guy Gardner and reacquiring it, Sinestro created the Sinestro Corps.
The yellow rings used by the Sinestro Corps are fueled by fear, and Lyssa Drak explains
that members of the Sinestro Corps are chosen for their ability to create great fear in
others. Through a string of Green Lantern stories titled Tales of the Sinestro Corps, she
describes the numerous ways in which Sinestro Corps members spread fear through the universe.
At the conclusion of these tales, she explains to Amon Sur that in order to become a member
of the Corps one must free themselves from a small prison. With their yellow power ring
completely drained of its energy, they must provide it with the spark it needs to accomplish
this feat by facing their own greatest fear. According to Ethan Van Sciver, the ring's symbol
is based on ancient carvings made by beings who look into the gullet of Parallax and survive.

Main article: Blue Lantern Corps
The first blue power ring.

As the Sinestro Corps War comes to a close, in Green Lantern (vol. 4) #25, former Guardians
of the Universe Ganthet and Sayd are shown using the emotion hope to create the first blue
power ring. In their discussion, they mention the formation of their Blue Lantern Corps.
The first Blue Lantern introduced is Saint Walker, who comes to the aid of the Green Lanterns
after they were ambushed by Atrocitus and his Red Lantern Corps.It's learned that Saint Walker
is from Sector 1, and he locates their second recruit (Brother Warth) in Sector 2.
In this way, Warth recruits a new Blue Lantern from Sector 3, and so on.

Though Saint Walker describes the blue light as being the most powerful, Atrocitus reveals
that without an active Green Lantern in their proximity they are only capable of the default
flight and protective aura abilities. While inside of the proximity of a Green Lantern's
influence, a blue power ring has the ability to heal wounds, neutralize the corrupting
effects of a red power ring, recharge a green power ring to twice its maximum power level,
and can drain the power from yellow power rings.[26][36][45] A noteworthy ability of blue
rings is the power to scan a target's psyche and create illusions based on their hopes.
A blue power ring is capable of feeding off the hope of other beings, eschewing constant
recharging while still performing impressive feats, including reversing a dying sun's age
by 8.6 billion years. The home planet of the Blue Lanterns and the Blue Power Battery is
the planet Odym, a beautiful and diverse planet orbiting the star Polaris.

Main article: Indigo Tribe
Indigo's power staff.

The Indigo Tribe, wielders of the indigo light of compassion, make their first extended
appearance in Blackest Night: Tales of the Corps #1 (July 2009). Very little is known about
them and they are considered to be unknown within the DC Universe at large. Indigo and her
tribe are first shown speaking a language that is unable to be translated by a green power
ring (which has a full catalog of all known languages).Ethan Van Sciver, who created the
initial design for the Indigo Tribe, explains that members of the group abandon everything
and devote themselves to compassion. As such, their uniforms have a basic, hand-made appearance,
their bodies are adorned with the Indigo Lantern symbol in body paint, and they carry carved,
lantern-like staffs with them. This corps exists to spread goodwill throughout the universe.
The Indigo Tribe is led by a pale female alien named Indigo-1, and Ganthet and Sayd have said
that the Blue Lanterns must seek out and form an alliance with the Indigo Tribe.

The Indigo Tribe has the unique ability to absorb the energies of other rings through their
staffs. The energy is then channeled into their ring and (depending on the motivation behind
the energy) turned against its source. When Indigo-1 encounters a mortally wounded Green Lantern
who attempts to keep her from getting involved in his battle with a Sinestro Corps member,
she uses his power to provide him with a mercy killing. When the Sinestro Corps member
subsequently attacks her, spouting banter meant to intimidate her, Indigo-1 uses his power
to create an enormous, monstrous, yellow light construct that scares her attacker away.
The exact function of indigo power staffs and their relationship to power rings of all colors
is still unknown.

Main article: Star Sapphires
Miri Riam's violet power ring.

At the conclusion of the Mystery of the Star Sapphire story-arc, the Zamarons realize that the
power of the Star Sapphire is too great for them to control and forge a violet power battery
and power ring out of the Star Sapphire gem. This allows them to distribute its powers
throughout an entire Corps of Star Sapphires. The first new recruit to the Star Sapphires
was Miri Riam of the planet Lartnec, who had just lost her husband to an attack by Mongul.
Established Green Lantern characters have also been inducted into the new Corps, including
Fatality and Carol Ferris.

Violet power rings are fueled by the emotion of love, one of the two emotions (the other
being rage) that most influence their user. At present, members of the Star Sapphires have
only been depicted as being female; however, during the Blackest Night panel at Comic Con
International 2009, Geoff Johns explained that "anyone can join, but most men are not worthy."
A unique ability of violet power rings is the power to encase their targets in violet crystal.
While trapped within these rehabilitation crystals, members of other corps have been shown
to be slowly converted into Star Sapphires. During the process their rings are drained of
their original abilities and replaced by the violet light. Violet rings are able to detect
when true love is being threatened, can create a connection to an embattled heart and use
it as a tether, and are also shown as being able to show others their greatest love. The
aura of the violet ring is asymmetric and ornate, reminiscent of vines and feathers. The
Star Sapphires are shown as being connected to an entity called "the Predator", which exists
as the physical embodiment of love.

Main articles: Black Hand, Blackest Night, and Black Lantern Corps
William Hand's black power ring.

In the concluding issues of the Sinestro Corps War story-arc, Superboy-Prime hurls the
Anti-Monitor into space. He crashes onto the dead planet of Ryut and is encased within a
Black Power Battery of unknown origin. The symbol on black power rings (a triangle pointing
downwards, with five lines radiating upward from the base) is the same symbol used by Green
Lantern super-villain Black Hand. It is also the symbol of the Hand family's mortuary.
Black Hand becomes the first Black Lantern after killing his family and committing suicide.
Scar comes to him and regurgitates the first black power ring. It places itself on his finger
and bids him to rise. Scar then explains that Black Hand is the living embodiment of the 
Black Lantern Corps as Ion, Parallax, and the Predator are to the green, yellow and violet
lights of the emotional spectrum respectively.

Black power rings are wielded by the deceased. In addition to the abilities granted to them
by the rings, Black Lanterns retain any superpowers they may have had in life. If the ring
bearer's body is severely damaged or destroyed, the black ring will partially reconstruct
the body, restoring it to a working state. During the creation of Blackest Night, Johns
wanted to resurrect the Black Lanterns in a way that seemed horrifying and emotionally
disturbing to the living characters they encountered. To accomplish that effect, the B
lack Lanterns have personalities and actively seek out those who will be affected by
their appearance. Well known DC characters resurrected as Black Lanterns include:
Earth-Two Superman, the Martian Manhunter, and the original Aquaman and Firestorm.

The first black power rings possess no charge, but each time a Black Lantern kills
someone and removes their heart, .01 percent power is restored to every ring in the Corps.
The exact limitations of black power rings have not yet been fully explored; however,
even at low power levels, black rings enable their user to fly and create black energy
constructs. Black power rings are capable of regenerating typically fatal injuries
inflicted upon their users (including decapitation). Black Lanterns are also able to
read the emotions of the living as a colored aura that correlates to the emotional
spectrum (red for rage, violet for love, etc).
