Lake Madō (魔洞湖 Madō-ko) is the lake which the Darkness of the Land aka Deboss Hell lies underneath. The tenth Zyudenryu, Bragigas, ended up in what became the bed of Lake Madō after being dragged underground by Great Land Devil Gadoma. Bragigas was revived once all 13 of the Guardians’ Secret Stones were gathered by the Kyoryugers, while Debo Tairyon fished out the core of Gadoma so his body could be restored. While the lake was dried up, many Debo Monsters were brought back from Deboss Hell, ingesting items to regain their physical forms before the lake was restored. The Kyoryugers were forced to deal with these revived Debo Monsters.
