Тіерія Ерде

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 their "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. This direct connection with Veda permits him to know more about Celestial Being than his fellow Meisters.

At the start of the series, he has an extremely rocky relationship with Setsuna
