Master Shaper Nei Rin, a benevolent character that worked diligently upon a genetic project to reform the ecosystem of a planet devastated by her people in the past. She was a very selfless woman focused upon healing the sick and curing the diseases that plagued them along with trying to improve the appearance of her people and atone for their crimes. Note, the Yuuzhan Vong war cost over 65 trillion lives.
Tsavong Lah, the one in the image with the orange eyes holding the serpent. He was the Warmaster of the Yuuzhan Vong longer than many that had held the rank, he oversaw the initial attack and deaths of trillions with his campaign. However his ultimate downfall came with his obsession over Jacen and Jaina Solo, believing they were religious figures brought out to test him that he had to capture and defeat personally.
Nas Choka, a military leader that rose up through the ranks from being a simple grunt. A powerful fighter and intelligent Warmaster that adapted often to his enemies and led successful campaigns until the end of the Yuuzhan Vong Empire. It should be noted that rather than kill himself at the end of the war he became the voice of the Empire's people, and surrendered them to the Galactic Alliance and helped in creating a more peaceful end rather than the mass suicide attack that was planned.
