Samurai Warriors Edit

Ieyasu is the proud lord of Mikawa and an old friend of Nobunaga. Due to political affairs, he was a former ally of Yoshimoto Imagawa. When Imagawa is ambushed atOkehazama, Ieyasu and his men choose to side with the Oda. In the first game, he plays a relatively supportive role and a secondary villain in other characters' scenarios -such asYukimura or Goemon's stories. He schemes to take the land for his own by heavily relying on his vassals and resourceful shinobi, Hanzō. His leadership qualities are better demonstrated in Samurai Warriors: Xtreme Legends though he still relies onTadakatsu for consolation.

In the second game, Ieyasu is already allied with Nobunaga and aids his ally by attacking the larger Asakura army at Anegawa. He then tries to attack Shingen but falls victim to the elder general's ambush. Escaping with his life, Ieyasu mourns the vassals lost for his safety. Tadakatsu assures him that they died protecting the world of peace his lord envisions, strengthening Ieyasu's resolve. Shingen and Nobunaga eventually pass away and Ieyasu becomes one of the two powerful men of the land. To settle their differences, he challenges his rival, Hideyoshi, at Komaki-Nagakute. Although he won the battle, Ieyasu thought that killing his rival would only throw the land into confusion once more. Therefore, he keeps his ambitions in check and lets Hideyoshi rule for the time. As he assists the western siege at Odawara Castle, he gainsMasamune as an ally.

After Hideyoshi's passing, Ieyasu decides to set his plans into action and clashes with the Toyotomi loyalist, Mitsunari. After winning the battle of Sekigahara, Ieyasu becomes shogun and finally unites the land. Remaining Toyotomi loyalists band together to oppose him at Osaka Castle. Fearing that failure to affirm his grip would throw the land once more into chaos, he leads his army to destroy them. With the land finally at peace, Ieyasu has completed his arduous journey for unity.

His dream stage focuses on a "what if?" scenario prior to the Battle of Sekigahara. Ieyasu and Ina are unexpectedly isolated from their allies when Kanetsugu and the Uesugi army heads straight for their location. His enemies also include the Sanadaarmy from Ueda and Yoshinobu Satake.

In Samurai Warriors: Katana, the final chapter of the Ascendancy scenario mentions Ieyasu helping the Oda ambush the other enemy factions at Sekigahara offscreen. The Swordsman scenario has him cease the attack on Ōsaka Castle out of fear and respect for the protagonist's victory over Tadakatsu. During the Stealth scenario, he and his forces rush back to Mikawa after learning of Kotarō's hostile takeover. Disgusted by the Fūma clan's destruction of his lands, the warlord personally challenges them to the death and loses. He warns the player not to heed Kotarō's philosophy before succumbing to his wounds.

In the Unification scenario, Ieyasu puts aside his feud with Hideyoshi to keep the protagonist's forces from expanding. He launches a decisive battle against the player at Sekigahara after consolidating the eastern regions to his rule. Much to his disbelief, the opposing army gains the upper hand by clearing a path to his main camp. Unable to fight back, he discards his own ambition in favor of peace.

Ieyasu begins his story in Samurai Warriors 3 similar to his previous story and his goal for peace is emphasized. Slaying Nagamasa at Anegawa, the Oda army conquers the Takeda and the land has a brief reprieve from war. Ieyasu stations himself near Kyoto to oversee the growing serenity until Nobunaga suddenly dies at Honnōji. Determined to live and see his friend's dream for peace realized, Ieyasu flees. Breaking through Kotarō andMotochika at Iga, he safely arrives in Mikawa. After Hideyoshi slays Mitsuhide, it became a manner of time before the powerful generals would compete their ambitions against one another at Komaki-Nagakute. During the conflict, they both grow to respect one another and realize that they truly shared similar goals. When Ieyasu defeats Hideyoshi, he insists that they work together to achieve the dream that their lord sought.

He gladly supports Hideyoshi's vision until the latter's natural death. Mitsunari, who disagrees with Ieyasu being the land's greatest man, assembles an army to oppose him. For the hopes of his fallen friends and for the future, Ieyasu defeats him at Sekigahara and Yukimura at Osaka Castle. Naming Yukimura as the greatest warrior in the land upon the younger man's death, he is pleased to see everyone's dream fulfilled at last and desires to treasure the hard-fought peace.

Sengoku Musou 3: Empires gives him the chance to quickly fulfill his ambitions in Masamune's story by allowing the younger man's army to pass through Mikawa in exchange for rulership over the land once the Toyotomi are wiped out. His story route takes place right after Hideyoshi's death. Although Ieyasu is entrusted to look after the Toyotomi clan's welfare, their continuous infighting convinces the warlord to unite the land under his rule. After subjugating the Uesugi at Hasedō, he survives an assassination attempt by Sakon within his own home. He also rebuffs Masanori's pleas for leniency towards Mitsunari, but the former vows to make an era where such requests can be granted.

His army's victory in Sekigahara is kept intact even though the interference of the Sanada and Fukushima clans enables Mitsunari to escape. Rather than execute his enemies for their last stand at Ōsaka Castle, he persuades Hideyori to forsake his family name and send the Toyotomi followers to exile under the pretext of preserving their late lord's will. With the land at peace once more, the Tokugawa officers celebrate their victory by launching fireworks to the sky.
