The Batta Yummy was one of Amadum's monsters in the world within the Magic Stone. With the Arch Orphnoch and Alternatives 01, they attacked and defeated Beast when he intruded in Amadum's lair as he planned to harness the Kamen Riders power, forcing Beast to his proper place in space and time. The three monsters later appeared to capture the young Haruto and Koyomi, fighting off Haruto, Rinko, and Shunpei, when they tried to stop them. They brought the children to Amadum as Tsukasa Kadoya gave him the thirteenth and last Rider Ring (Fourze). The Kamen Riders refused to fight Haruto, saying they fought for human freedom and not just justice, engaging Amadum's monsters. The Batta Yummy, Arch Orphnoch and Alternatives 01, along with several other monsters, were destroyed by Wizard and Decade.
