He starts as one of the two talented strategists at Nagashino in Samurai Warriors 3. He is responsible for ensuring the enemy's complete elimination while Hanbei blocks the Takeda's escape path. Both he and Hanbei use their talents once more when Motonari raises an uprising at Kizugawa. They win the conflict, but Hanbei tires from the effort and soon collapses. Kanbei visits his bedside and Hanbei assures that he will always be the "light" for his friend. Hanbei eventually dies but Kanbei acts unaffected by the loss, stating that an obstacle in the path for peace has just been eliminated.
Hideyoshi suppresses the Mōri family after the conflict, but Nobunaga is soon assassinated at Honnoji. At first, Hideyoshi denies his lord's death and doesn't seem intent to take action. However, Kanbei goads for Hideyoshi to take Nobunaga's ambition for himself as there are no other in the land who could stop him. Stating that the flames at Honnoji have merely opened the gates for Hideyoshi's ambitions, Kanbei's words convince Hideyoshi to march against Mitsuhide at Yamazaki. Though Hideyoshi achieves his dreams, he passes away due to illness and power shifts to Ieyasu's favor. Kanbei decides to serve Ieyasu for the land's peace and faces the Tachibana and Motochika at Ishigakibaru.
Suppressing the Western army at Ishigakibaru, Kanbei is unimpressed by Kiyomasa and the remaining Toyotomi officers and sees their survival as the last "flame of chaos" that needs to be extinguished. He therefore continues to serve under Ieyasu during the siege of Osaka Castle, facing Kiyomasa in battle and defeats him. After Ieyasu's victory, Kanbei inspects Kiyomasa's body, states that the Toyotomi are now finished, and walks away. Kiyomasa, who was playing dead when Kanbei had his attention to him, uses the last of his strength to strike down the strategist. Although he tries to make a snide remark about Kiyomasa's effort, Kanbei figures that he possibly stands as the greatest threat to peace and accepts his fate to die with the rest of the Toyotomis.
Role in Super Smash Sisters
Kanbei Kuroda appears in Super Smash Sisters as a non-playable strategist. He can use dark magic to help the girls in combat and his green orb which he creates next to him from his crystal ball before battle. Kanbei can even use telepathy like Krystal and levitate his opponents to break their limbs. He may seem kind to the girls yet will get grumpy when asked to bond with Glass Joe for Kanbei will just telepathically punch him.
