Sima Yi

The Wei strategist, Sima Yi was studying, when he heard that Wei was looking for a stratigist. Sima, who knew he could use his talents to rule the land one day readily accepted.

Dynasty Warriors
In Dynasty Warriors 6, his storyline revolves around him using Cao Cao's ambition as a means of gaining control of the land by any means necessary. Early on into his Musou, he learns of Cao Cao's plans for the future, and feels as if "scales" have fallen from his eyes, or being enlightened. After Cao Cao defeats the other two Kingdoms, Sima Yi is placed to guard Han Zhong. Shortly after, he starts a rebellion, uniting the officers under him as if they were his own. In his final cutscene, he is shown slaying Cao Cao, and ascending the throne.

Warriors Orochi
In the original Warriors Orochi, Sima Yi serves Orochi faithfully, gladly breaking his bonds with Wei. He can be unlocked at the Gaiden stage, Odawara Castle in the Samurai storyline. If the player successfully executes two fleeing officers, therefore ruining Sima Yi's trap, Sima Yi will be in awe of the Coalition's genius, and joins their cause. In Warriors Orochi 2, Sima Yi works in Masamune's army. In the Samurai Warriors story, at Chang Ban, the player and Shingen Takeda can outwit Sima Yi, and, he again, joins the Coalition.

Kessen
Sima Yi is a confident and talented magician for Wei in Kessen II. He is first seen strutting into Cao Cao's throne room midway through the game, wondering why he can't find the "great hero of the land". He bluntly ventures that Cao Cao is the cause of the land's natural disasters as they continue due to the conqueror's selfish desires. He states that the lord will lose to Liu Bei if this continues, which gets an angered response from Cao Cao. Sword drawn to the offender, he growls for his name to which Sima Yi politely bows and introduces himself. Cao Cao likes the sorcerer's fearless nature and recruits him on the spot. His battle strategy is the best way to fend off an angry Ma Chao.

Gameplay
In Dynasty Warriors 6, Sima Yi's weapon of choice are gloves that protrude long and thin of wire from his fingertips. His deadlock attack shows that these wires are strong enough for him to hook them into an opponent, lift them, and smash them to the ground. He gains a good amount of crowd control attacks (especially during higher Renbu levels) and relies considerably less on magic than before. In some ways, he resembles a long range character, as his attack efficiency is somewhat weakened while he is close to his opponent. However, this setback can be bypassed if the player has mastered when to properly evade.
