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 siege towers being built.

Dynasty Warriors 8 has Gao Lan appear only at Guandu. Once Yue Jin takes the garrison north of Guandu castle, Gao Lan along with Chunyu Qiong and Lu Xiang will advance on him and usually be defeated. Contrary to previous installments, Gao Lan will not defect to Cao Cao's forces if he is still alive when Wuchao falls.

Gao Lan appears in Romance of the Three Kingdoms as an officer of Yuan Shao. Most games give him 70's leadership and 80's war, with his other stats being in the 50's or 60's, as well as a high cavalry rating. In the eleventh game's Power-Up Kit expansion, his unit will defect to Cao Cao's forces with Zhang He's in the Guandu challenge scenario once Wuchao is destroyed. Some installments feature an event revolving around the conflict at Guandu, in which Zhang He and Gao Lan usually join Cao Cao's ranks.
