Treize is the charming, charismatic leader of Oz - and of the Specials, the elite Earth Alliance taskforce which serves as Oz's disguise. He is a pure aristocrat, who lives by a code of chivalry and conducts himself as a gentleman even while plotting cruel treachery and bloody revolution. Treize's wicked schemes are rooted in a nobleman's conviction that conflict and war serve to strengthen and improve the human spirit. He is admired by Oz's soldiers; feared by his Alliance superiors; and a close, trusted friend to ace pilot Zechs Merquise.

Often called the most difficult-to-understand character, Treize has an idealistic view toward war. As he stated in his own words, "selfishly combine war with one's own value of beauty". His rationale is very much similar to Zechs, though the two sides later on became enemies.
