Baron Tomsen is one of the main characters in the 7th installment of the Kamen Rider: Armor Warrior. Before the Inves Games, he received a Sengoku Driver as well and a Banana Lockseed, which allows him to transform into Kamen Rider Baron. In one episode, after being left cornered with his Genesis Driver broken and knowing that his Sengoku Driver cannot compete against Victor, he eats a fruit of the forest and transforms into a Helheim Overlord known as Lord Baron.
