Pang Tong
Pang Tong (龐統) originally wanted to serve under the Wu, but the leader of Wu thought he was ugly and didn't let him serve the Wu. Later, he went to Liu Bei and served under him. When Liu Bei went to meet the ruler of Shu at that time, Liu Zhang, Pang Tong advised Liu Bei to kill Liu Zhang. Unfortunately for him, this idea was turned down.
When Liu bei attacked Liu Zhang, Pang Tong was to go across a pass to meet with Liu Bei. He was ambushed while crossing it, got shot in the chest and died.
His name usually is of the same status as Zhuge Liang.
