from Oa's Central Power Battery and destroying the planet in the process, Proselyte sacrifices himself by passing into the Source Wall in order for the reservoir to be refilled. Powers and abilities The Indigo Tribe harnesses the indigo light of compassion. Robin S. Rosenberg, a clinical psychologist and editor of the anthology The Psychology of Superheroes, describes compassion as being able to have empathy for someone while maintaining enough distance to understand their motivations. The indigo ring has basic power ring abilities such as flight and aura projection, as shown on the cover of Blackest Night: Tales of the Corps #3. Members can use indigo light to teleport themselves and others over vast intergalactic distances; this drains much of the ring's power, so the wearer uses it sparingly. The indigo light can also heal individuals with great empathy but exposes people to the pain they have inflicted on others. The Indigo Tribe distinguishes itself from the other Corps in that a member uses a power staff instead of power battery to charge the indigo ring, as depicted in Blackest Night #5. Unlike the power battery lanterns, the staff appears to be a part of the Indigo Tribe's uniform, appearing whenever a user puts on the ring and transforms into costume. The Indigo ring not only stores indigo light energy, but also is capable of channeling the energy of other emotional lights; the ring can therefore emulate the abilities from other Corps. In Blackest Night, Indigo-1 and Munk use a combination of different emotional lights to destroy members of the Black Lantern Corps. Black Hand is able to charge Hal Jordan's ring with green light although it is not as powerful as a standard charging. In Green Lantern Corps (vol. 2) #42, Munk explains that this ability is only effective from "direct and intimate discharges." Whereas a Corps member projects a light display in front of the emblem on the uniform when using abilities, the Indigo Tribe member projects the Corps symbol in an indigo light display from the "pod" on the staff. When the Tribe member manipulates another light, the symbol of the Corps corresponding to that light is projected in front of the Indigo Tribe emblem painted on his or her forehead. In the bonding process, the indigo ring forces its wearer to feel nothing but compassion. By blocking out all other emotions, the wearer can channel other emotions
