Liang Zhuge

Zhuge Liang is a placid and calculating man who is always thinking one step ahead. He often states that every turn in battle is a part of his effortless planning. Like the novel, he speaks with a polite and proper manner at all times, albeit terrifyingly so when he completely stumps his enemies. Though his intentions are sometimes questioned, he is indeed loyal to Liu Bei as he admires his lord's humble and noble qualities.
Perhaps a bit too confident of his abilities, he only half acknowledges his rivals from Wei and Wu, Sima Yi, Zhou Yu, and even his own colleague Pang Tong. While they are intent on befuddling him and proving their mental superiority, Zhuge Liang will haughtily denounce their efforts.
