Fictional character biography
Ganthet is one of the Guardians of the Universe. However, where most of the Guardians are very stern 'by-the-book' characters, Ganthet has a personality that is more human-like, including displays of empathy, kindness and concern for an individual, instead of only thinking of the Green Lantern Corps. In various DC crossover limited series such as Kingdom Come, Ganthet is shown as being part of the Quintessence, a group of gods who oversee the universe (or multiverse) in its entirety, although they seem to focus on Earth.
Although he has been portrayed as looking like the other Guardians, Ganthet is often distinguished by tying his hair into a long ponytail, as the other male Guardians have shorter, unkempt hair.
Green Lantern: Secret Origin
In the Green Lantern: Secret Origin story, Ganthet (without ever revealing himself physically) asks Sinestro to investigate the death of Abin Sur (through non-official channel, bypassing protocol), thus leading to Sinestro's first meeting with Hal Jordan, happening in Earth.
