This masked warrior is Oz's top mobile suit pilot. Up until now, Oz has disguised itself as the Earth Federation's elite "Specials" taskforce, and Zechs has accumulated numerous distinctions during his career in the Specials. He earned the highest marks in the history of the Lake Victoria military academy, received the first two-rank promotion in the history of the Specials, and acquired the nickname "Lightning Baron" for his exploits. Zechs's accomplishments have made him a hero among Oz's soldiers, but this master soldier is cunning enough not to overestimate his own abilities or underestimate those of his enemies.
His real name is Milliardo Peacecraft. Due to the fact that he felt that his hands had been stained with blood, he felt unqualified to be the successor of the Sank Kingdom. In the past he hid his true identiy in the OZ and did so by wearing a mask. He was known as the "Lightning Count".

Zechs is often compared with by other gundam fans to Char. This may be have been the similarity in both looks as well as the aura of tragedy that surrounds both of them. In Zechs' case, tragedy is referred to the events that are brought on by his own actions, not because of his past.

Most GW fans had expressed that they didn't know what he was thinking most of the time. But his point and rationale behind his actions and thinking were made clear in episode 46.
