The Gunpla Force Battle Tournament is a big event held in GBN once per year. Competing in the final round are Avalon, led by the champion Kyoya Kujo, and the elite 7th Panzer Division led by the cunning Rommel. Starting with Kyoya's Gundam AGE II Magnum, a variety of Gunpla take to the field to determine which is the strongest force!

Similar to the previous Battlogue series, the ONA features Gunpla battles based on fan votes including characters from both Build Divers and Build Divers Re:Rise.
