Batta Yummy

The Batta Yummy (バッタヤミー) is a grasshopper Yummy created by Uva by using the desires of Susumu Kanbayashi (神林 進), a father with a sense of justice who attended law school and failed to pass the board exam as a prosecutor. As a result, the Batta Yummy develops a warped hero mentality and attacks anyone who Susumu considers evil, attacking Kamen Riders OOO and Birth when they interfere. Managing to evade Kamen Rider OOO Takajaba's Giga Scan due to Susumu's dependence, the Batta Yummy continues his attack on untouchable criminals as Susumu begins to see realize too late that his desire for justice is making him as much of a monster as those he wants to take down. After talking Susumu to not to rely on justice but instead on protecting those dear to him, Eiji becomes Kamen Rider OOO Tajadol Combo and uses his Giga Scan to incinerate the Batta Yummy.

The Batta Yummy is voiced by Daisuke Endō (遠藤 大輔).
