Kaito Kumon

Kaito Kumon (駆紋 戒斗 Kumon Kaito?) is one of the main characters in the 24th installment of the Kamen Rider Series, Kamen Rider Gaim. He is the founder and former leader of Team Baron, Team Gaim's rival until he chose Zack as his successor, and gave him a mass production Sengoku Driver as a parting gift. Growing up poor, he always believed that the weak warriors are exploited after Yggdrasill took everything from his life. After watching Gaim battle the Shika Inves, he received a Sengoku Driver as well and a Banana Lockseed from Sid, which allows him to transform into Kamen Rider Baron (仮面ライダーバロン Kamen Raidā Baron?). In Sengoku Movie Battle, he was named Kamen Rider Bujin Baron (仮面ライダ武神バロン Kamen Raidā Bujin Baron?), but dropped it after Bujin Gaim's defeat. Kaito is also addressed as Monsieur Banane (ムッシュバナーヌ Musshu Banānu?) by Oren Pierre Alfonzo.

In episode 43, after being left cornered with his Genesis Driver broken and knowing that his Sengoku Driver cannot compete against his foe, he eats a fruit of Helheim and transforms into an Over Lord Inves known as Lord Baron (ロード・バロン Rōdo Baron?).
