Chang Wufei
The stern pilot of the Shenlong Gundam is the proud offspring of a legendary warrior clan, who were exiled from China to a decrepit space colony by a fearful government. Wufei adheres to a strict code of honor and justice, seeking to protect the weak and punish the guilty. But his pride is something of a weak point - when pushed too far, Wufei's huge ego has a tendency to break.
Unlike the other Gundam pilots, even the relatively antisocial Heero and Trowa, Wufei prefers to operate alone and frequently seems to have a better idea what's going on than his blundering fellows. His only companion is his Gundam, which he calls "Nataku" after the Chinese mythological hero.
In Endless Waltz Wufei, driven by his warrior's pride and a burning sense of justice, has found himself unable to adapt to a world at peace. As he sees it, the new era has simply discarded the soldiers who fought to bring it about, and he has no choice but to seek out a new battle. Thus, he declines to join his former comrades in disposing of his Gundam, and instead puts it at the service of the rebel Mariemaia Army.
In an Endless Waltz flashback, we see how Wufei rebelled against the original plan for Operation Meteor, which called for dropping his home colony onto Earth. Instead, he took the Shenlong Gundam and went to Earth to fight the enemy directly. Ironically, the colony was nonetheless destroyed in the course of the war against OZ, leaving Wufei without a home or family to return to.
