Tieria Erde

Birthday: December 9th
Height: 177 cm (5'9")
Unit: GN-004 Gundam Nadleeh

Tieria seems rather stoic and distant, although also proud and arrogant. Constantly believing he has the best interests of Celestial Being in mind, he rarely acts out of impulse, and has little patience for the impertinent. To this end, he often clashes verbally with the other Gundam Meisters, as well as his "superior", Sumeragi Lee Noriega, on topics ranging from insubordination to ideology. Tieria is often noted for being on an extremely high horse, looking down upon others. Tieria also shows an unnatural loyalty to Veda, the supercomputer of Celestial Being, which Tieria can directly interface with. This link between Tieria and Veda can explain Tieria's holier-than-thou attitude, and his belief that he is a judge of the members of Celestial Being.Tieria is shown to also be rather intelligent, and capable of making competent snap decisions. His direct connection with Veda permits him to know more about Celestial Being than his fellow Meisters.

At the start of the series, he had an extremely rocky relationship with Setsuna; the former does not understand why the latter was chosen by Veda as a Gundam Meister, and believes Setsuna's brash actions and random insubordination will breach the code of secrecy of Celestial Being. However, he eventually found more a common ground with Setsuna in their vehement dislike of Team Trinity, even going so far as to back him up when he decides to combat them; this unexpected move, along with the teamwork strategies used in the battle, surprises the rest of Celestial Being.
