Wei (Warriors Orochi)

From Koei Tecmo Wiki
Cao Pi and Mitsunari Ishida in Warriors Orochi.

The Wei force refers to the mixed army exclusive to the Warriors Orochi series. The characters in this particular faction all follow a character who originated from Wei. As Orochi conquered the resistances against him, Wei was one of the armies determined to destroy the snake demon. Despite their efforts, their army was defeated and Cao Cao was believed dead. The remaining forces were subjugated into Orochi's army. Cao Pi, Wei's designated leader, initially acts as a loyal general but schemes to eventually surpass his overlord. Following Orochi's defeat, Cao Cao resumes command of the kingdom and personally explores their new surroundings.


When the worlds were distorted and combined, Cao Cao organized his troops in the hopes of conquering the new, but strange, land. Originally stationing himself and his loyal retainers near Yi Ling, he was attacked by Orochi's forces, who were lured in by the prestige of the Hero of Chaos. Led by the Wu forces under Sun Quan, Cao Cao's forces remain calm against the new threat, but crumble against the overwhelming might of the Serpent Army. Cao Cao, severely wounded, was forced into hiding with Dian Wei. The remaining forces that were brought to Yi Ling, however, were scattered around, though all made their individual searches for their lord. The rest of the Wei forces would then be led by Cao Pi, who pledged allegiance to Orochi.

The first game has Cao Pi and the Wei army appear prominently in the other stories, often acting as lackeys and commanders of the Orochi Army until the final gaiden stage or at Koshi Castle. In the Samurai story, Nobunaga catches on to Cao Pi's real intentions and makes small moves to quietly assist him, which is repaid by reinforcements at Koshi Castle. For their own story, Cao Pi is tasked with suppressing Huang Gai's rebellion at Kuzegawa, where he recruits Xu Zhu and exchanges words with Xiahou Yuan and Huang Gai before casually releasing both.

Following this, he is called to fight Nobunaga Oda's sudden attack at Tian Shui. Despite Nobunaga's attempt to decipher Cao Pi's true motive, the prince dismisses Da Ji's suspicions of betrayal. Nonetheless, Nobunaga's actions cause Da Ji to place Mitsunari Ishida at Cao Pi's side as an observer, and the pair are tasked with joining Sun Quan to hunt down Sun Ce's deserting forces at Xiakou. Once again, however, Cao Pi chooses to undermine their cause by releasing Sun Ce and Zhou Yu. When Da Ji inquires of the fate of their prisoners, Mitsunari would unexpectedly step in, claiming that the pair could've easily been body doubles.

Cao Pi would finally move to prove himself moves on to stop the insurrection of Xiahou Dun, Pang Tong, and Xiahou Yuan at Yi Ling, convincing all three to join his side. As time passes, he stages his own revolt against Orochi capturing Da Ji at Odawara Castle after defeating her illusion of Cao Cao and Sun Jian and also convincing Huang Gai to join their ranks.

Hoping to bolster their ranks for the upcoming battles, Cao Pi formally declares Wei's return to independence chooses to wage war against the Azai at Chencang, successfully recruiting Nagamasa, Oichi and Gan Ning. Believing they were ready, Cao Pi would launch an attack on Dong Zhuo's forces at Yamazaki, but Da Ji's betrayal and the strategies of both Zhuge Liang and Sima Yi push the Wei forces to their brink until Cao Cao and Dian Wei arrive to their rescue.

Although Cao Cao returns, in recognition for his son's leadership, Cao Pi is allowed to lead their final battle against Orochi at Koshi Castle. Despite attempts to protect bombard the Wei forces with cannons, Cao Pi turns the tables by taking the enemy cannon fortresses and firing them at Orochi's castle to force down the enemy drawbridges. After a final battle, Orochi would finally be slain, and the Wei forces would celebrate the return of their lord.

In the second game, remnants of Orochi's army quickly reform as Cao Cao decides to also build up his own force. Cao Cao, along with the mysterious woman Nu Wa, drift throughout the land, with Zhang He and Dian Wei acting as bodyguards for their lord. At Si Province, Kunoichi informs Cao Cao that an outlandish 'circus' of an army, led by a monkey, had approached. Cao Cao asks if Nu Wa knows anything about it, but she denies to know anything. During the battle, Cao Cao's army combats a force led by a monkey and Dong Zhuo, who hasn't seemed to change at much at all, save for the fact that he now took the position of a "monkey-handler". At Si Shui Gate, Cao Cao finds out that Nu Wa has been testing him, after they face Lu Bu, while absorbing the Xiahou Dun army. After the battle, Cao Cao is suspicious with the appearance of a mystical monkey which he finds out to be named Sun Wukong, Da Ji's involvement, and Lu Bu.

Nu Wa finally reveals that Da Ji has the intention of reviving Orochi, while Sun Wukong seems to be working towards the same goal. With the knowledge of a high level of danger, Cao Cao seeks to find any potential ally. He along with Cao Pi sent letters requesting for allies, and sends Zhang He to gain Yuan Shao's forces at Shizugatake. While Cao Pi would try and spur Wu back into action by attacking them at Nanzhong. Both efforts would yield successful results as a defeated Yuan Shao would agree to merge their forces for the greater good, while Taishi Ci would act as Wu's envoy for Wei.

At Ji Castle, Toshiie Maeda and Magoichi Saika face a Date army, led by Sima Yi. Cao Cao, thinking this as an opportunity to defeat the enemy and gain allies, sends Xiahou Yuan to help them out. The plan works out in success subduing the Date army. Cao Cao leads them to be absorbed into his own army. In the aftermath, Nu Wa ponders deeply about Cao Cao. He successfully gained an alliance with Wu, absorbed two armies into his own, and was even able to see through Nu Wa. She remarks that Cao Cao is more fearsome and deadly than Kiyomori Taira, and if turned down the wrong path, will be almost unstoppable.

Despite Cao Cao's efforts, Orochi is successfully revived, albeit in a weakened and incomplete state. Despite this, their army would attack Cao Pi's position at Komaki-Nagakute, forcing Cao Cao and Dian Wei to rush to their aid. Once their forces combine, Pang Tong uses a fire attack to destroy the enemy center, allowing the Wei forces to surge into the Orochi army's camp. In response, Kiyomori teleports the weakened Orochi away from the Wei army's clutches. Finding Orochi to be oddly incapable, Nu Wa explains that Orochi needed a girl named Himiko to restore his power, to which Cao Cao is disappointed that the woman has been keeping secrets yet again.

The Wei army would pursue Himiko and Da Ji at Yamatai, but Da Ji stalls for time and ambushes Jiang Wei forces. Despite this, Nagamasa arrives and pledges the Azai to Cao Cao's forces. Ultimately, Da Ji would have the last laugh as gives herself up for capture to ensure Himiko's escape to Kiyomori. In a final attempt to stop Orochi's true revival, Xiahou Dun leads a force to hunt the sorcerer at Tong Gate, but are tricked and surrounded by ever-reviving enemies from all sides. As fate would have it, Nobunaga's forces would arrive, exposing the magic used by Kiyomori's forces to revive their allies and helping the Wei forces target these magicians. Though Kiyomori is slain, he reveals that he has already completed the ritual, and that they would have to face his lord in his true strength.

Standing as one, both Cao Cao and Nobunaga would advance towards Orochi X at Guandu, and prepare a large scale ambush by luring the enemy's frontlines to the center of the field before having ambush troops attack them simultaneously. Orochi X would reply to this by instilling fear into his army, pushing them to fight harder, but both Liu Bei and Sun Jian would come to the aid of Cao Cao, and the warlords would come together to slay Orochi for the second time.

In the third game, the Wei army begins its path of conquest, and Cao Cao has a very strong rivalry with Nobunaga Oda. At one point, a detachment of Wei forces, led by Cao Ren, assist the Wu army in cornering Kiyomori at Hefei, but Kiyomori uses his newfound powers to take control of many Wei and Wu officers instead. Additionally, Cao Pi and Sima Yi had also succeeded in cornering Da Ji at Tong Gate though she successfully escaped their grasp once more. By the end of Demon army's campaigns, it is presumed that many of Wei's officers had now either become enslaved by Kiyomori, were killed or were separated from each other. Nonetheless, Cao Cao himself disappeared once more and could no longer be found, and many of Wei's officers perished one at a time. The largest group of remnants would end up joining Sima Zhao, who was accompanied by Wang Yuanji, Zhuge Dan, and Zhang Liao at Ueda Castle, though Sima Zhao would leave to try and defend Odawara Castle, the other three officers would be killed in the ensuing battle at Ueda castle.

When Sima Zhao returns to the past with Da Ji, the Wei forces misinterpret her presence as an alliance, and attack the Coalition at Tong Gate. Although Cao Pi is defeated, he and Sima Yi are convinced of the intentions of the Coalition, and various Wei officers are sent to aid Sima Zhao in secret. Sima Yi is then sent to aid the Takeda-Uesugi army at Kawanakajima  once the Coalition starts moving for Chengdu. Meanwhile, Cao Cao, who is unconvinced, defies the Coalition's march to Chengdu at Fan Castle, and is defeated by Ma Chao, who is reluctant to release his desire for vengeance. After his defeat, Cao Cao promises to help the coalition, and aids Liu Bei's retreat from Chengdu.

With all the leaders of the Three Kingdoms and the Sengoku period together, the group would advance towards Orochi X's lair at Koshi Castle, and Cao Cao and the other warlords would fight to prove their mettle against Susano'o.

In Ultimate, many of Wei's officers rejoin the kingdom in the new timeline, but Wei is involved in numerous conflicts resulting from Kyūbi's scattered tails. Believing that the Oda had betrayed their alliance, the Wei officers attacked Nobunaga at Nanjun, but were repelled. Later, a fake Nagamasa convinces Ma Chao into attacking the Wei forces. Later, a fake Pang Tong induces the Shu forces to also attack Wei. Having had enough of these tricks, Cao Cao works with the other warlords to stop Kyūbi, and Cao Pi and Guo Jia play a major role in her final defeat at Odawara castle.

Separated from each other once more when Zeus distorts the worlds, Wei's divisions were lost and many of its officers were unable to find their allies. Many of these lost officers would be found and recruited by the Oda army throughout Nobunaga's conquest of the new land. A small faction under Sima Yi would represent themselves and form an alliance with both the Date and the Oda armies. The largest group, however, would remain with Cao Pi's forces, who had allied themselves with Ares and the Olympian army.

When Liu Bei and Kenshin's rebel army begins gaining ground against the Oda, they attack the Date-Wei army at Tetorigawa, successfully swaying Sima Yi over to their side after defeating him. Once Nobunaga and the rebel army merge together to form the Coalition, all Wei officers under Nobunaga formally join their former enemies and begin investigating the mysterious appearance of the Olympians.

This eventually leads to their conflict with Cao Pi's faction, who stop at nothing to deter the Ares's enemies. Secretly, however, Cao Pi's own faction began leaking important information to the other humans, and many other Wei officers that served him were also aware of the prince's plan to sabotage the armies of Olympus from within. Cao Cao's own group, which had been lost and only arrived late into the world, would be found at Nagashino, sandwiched between Ares and Lu Bu's armies. Upon rescue, Cao Cao begins defeating his son in combat, who leaves a hidden letter for his father, revealing his true intentions as well as the methods to destroy the barriers protecting Zeus.

When Ares betrays and kills Zeus, the Wei Army is among the first to take flight and escape Odin's wrath. Banding together with the other warlords, Cao Cao and the others eventually stop Odin from achieving Ragnarok.
