Gao Lan

Gao Lan (rōmaji: Kō Ran) is an officer under Yuan Shao. Together with Zhang He, he defected to Wei at the Battle of Guan Du. He has very little mention in historical records and the previous sentences are all that is currently known of him. He has an expanded importance in the novel.

Role in Games
In earlier Dynasty Warriors titles, Gao Lan usually only appears at Guan Du fighting for Zhang He. Even if he defects, he does not appear again after the battle is over.

In Dynasty Warriors 6, he is one of the generals who attack Yanjin fort and is also buffed up. If he isn't defeated when Wuchao falls, he will defect along with Zhang He and Xu You.

In Dynasty Warriors 7, Gao Lan leads the ambush unit along the trail Xu You recommends. Taking the left trail allows one to sneak up and defeat his troops. Taking the center trail triggers him berating Xu You for defecting, and more seige towers being built.
