Role in Games

 * "I didn't think you were a mere slave to power."
 * ―Mitsunari Ishida; Warriors Orochi

Dynasty Warriors
Sima Yi is a scholar who thoroughly believes in his intellect. He appears sometime after Chi Bi as the master strategist of Wei. After Cao Cao's death, he is often depicted as the leader for Wei and appears in many of the series's decisive battles. He stars in Zhuge Liang's Northern Campaigns, and he is known in most titles to see through Ma Su's plot at Jie Ting. He also correctly reads the sign of his rival's death at Wu Zhang Plains and orders the army to charge. Depending on the title, he may then live to suppress the remnants of Shu and Wu.

His Legend Mode in Dynasty Warriors 4: Xtreme Legends takes place at Mount Qi. Thinking that Wei Yan will feed him with inside information, Sima Yi is lead into one of Zhuge Liang's traps. Surrounded by archers and trapped in a fire attack, he is saved by rainfall. With the heavens on his side, he fights his way through perilous odds, which forces Zhuge Liang to issue an all-out attack. Slaying the Shu generals, Sima Yi is able to escape safely.

In Dynasty Warriors 5, Sima Yi was born from a prestigious family and studied his life to become a renowned scholar. Summoned by Cao Cao to join Wei, Sima Yi demonstrates his skills as main strategist at Fan Castle and ask Wu for reinforcements. He serves Cao Pi after his liege's demise and kills Ma Su at Jie Ting. During the conflict, he meets Zhuge Liang and deems the Prime Minister to be his greatest threat. However, when his rival perishes at Wu Zhang Plains, he fears nothing while he crushes the other two kingdoms. With Wei as the land's ruler, it's implied that he plans to overthrow his master in due time.

His Legend Mode in the Xtreme Legends expansion pairs him with Cao Pi and Xu Huang. The trio work together to punish the traitor, Meng Da, at Xin Castle. While he holds himself within the castle's walls, he forces several Wei generals to fight their master. Sima Yi notes their weakened resolve and orders his allies to spark mutiny among Meng Da's troops. Striking the final blow against Meng Da, the defector accuses Sima Yi for false loyalties before he dies. The strategist replies that he is only biding his time.

Cao Cao summons for Sima Yi's talents before the Battle of Chi Bi in Dynasty Warriors 6. Originally bored and unimpressed by the land's chaos, he becomes fascinated by Zhuge Liang's tactics and his experience in battle. As he spends more time with his master, Sima Yi begins to form his own ambitions and image for the land. Consumed with his inner desires, he loses interest with his rival and works to destroy the other two kingdoms. Although ordered to keep watch in Han Zhong for rebellion, Sima Yi stages a coup d'état at Xu Chang with Zhang He and others. As he slays Cao Cao, his lord expresses his wishes to make a land for the people with his dying breath. Sima Yi, though acting uninterested, complies with his master's ideals to an extent during his rule.

Warriors Orochi
In the first game, Sima Yi serves Orochi faithfully, gladly breaking his bonds with Wei. He can join the Samurai forces during one of their gaiden stages. If the player successfully executes the two fleeing officers, therefore ruining Sima Yi's trap, he will be in awe of the coalition's genius and joins their cause.

In Warriors Orochi 2, Sima Yi works for Masamune's army. During the Samurai storyline, he faces the Sakon's forces at Chang Ban and is outwitted by Shingen. Impressed by Shingen's tactics, he decides to accompany them. In other faction story modes, he will survive to serve Orochi X.

Kessen
Sima Yi is a confident and talented magician for Wei in Kessen II. He serves as a strategist and adviser for Cao Cao. 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 one of the best ways to fend off an angry Ma Chao.

Personality
Originally introduced as a calm and gloomy strategist, Sima Yi eventually became a man who is more arrogant and conniving. He is known for his maniacal laughter and insulting friend and foe alike as "Fool!" or "Imbecile!" He doesn't truly believe in Cao Cao but is always eager to exploit every opportunity given to him. Prideful of his intellect and believing that he has an unsurpassed wit, he regards Zhuge Liang as a worthy opponent.

While usually known to be contemptuous and seemingly shallow, Sima Yi can also be easily humiliated when he can't predict the results of his actions. This mainly occurs during the spin-off titles in the Dynasty Warriors series, such as the mahjong title and Dynasty Warriors 6: Empires.

He trusts Zhang He's versatility for his plans and relies on him during the later parts of the Three Kingdoms period. In recent titles, he shares a loosely trusted partnership with Cao Pi and the heir refers to him by his style name. Sima Yi is fascinated with Cao Pi's abilities and generally finds him a better ruler than his father.

Dynasty Warriors
In Dynasty Warriors 6, Sima Yi's weapon of choice are gloves that protrude long and thin wires from his fingertips. Despite the claws' small and fragile appearance, the wires that protrude from them have good range. 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.
