Debo Akkumoon (デーボ・アックムーン Dēbo Akkumūn) is a sheep-like Debo Monster themed after sleep.


Debo Akkumoon was created to serve Luckyuro to invade the dreams of the Kyoryugers to give them constant nightmares. He has a tendency to end his sentences with "Moon" (ムーン, Mūn).

Debo Akkumuun can block blasts with his Memory-Foam Shield (低反発シールド Teihanpatsu Shīrudo), which is soft enough to absorb Gabutyra's charge and send him back flying once enlarged, make anyone fall asleep with his Restful Bomber (安眠ボンバー Anmin Bonbā), and attack with his Explosive Flame Bomber (爆炎ボンバー Bakuen Bonbā).

Luckyro then grows all three only for them to all be killed for good by Gigant Kyoryuzin's Super Zyuden All Gigant Explosion. The group all bowed and bid the Kyoryugers goodbye together before exploding, this time for good. Brave 37: Revenge! The Ghost Deboth Army
