Mega Monster Battle: Ultra Galaxy Legend The Movie
Beryudora was Ultraman Belial's trump card in preventing the Ultras from returning the Plasma Spark to the Land of Light. After being defeated by Ultraman Zero, Belial called forth all his monsters from his Giga Battle Nizer, as well as some more that rested in the Monster Graveyard. Together, Belial and all the monsters came together to form a colossus known as Beryudora. Belial personally rode atop his creation, controlling it from above with the Giga Battle Nizer.
Against the remaining Ultramen, EX Gomora, and the ZAP SPACY crew, Beryudora was unstoppable, effortlessly shrugging off every attack made by everyone. During the battle, Rei notices Belial's Giga Battle Nizer having been disarmed by Zero earlier in the battle. Using his own Battle Nizer, Rei causes all the monsters that make up Beryudora to riot against Belial's control, immobilizing Beryudora. With the opportunity, the ZAP SPACY crew fire the Pedanium Launcher from the Space Pendragon, Ultraman Leo and Astra fire their Ultra Double Flasher, Dyna fires his Solgent Ray, EX Gomora fires his EX Hyper Oscillatory Wave, Ultraman fires his Ultra Slashes, Ultraman Mebius turns into his Burning Brave mode and performs the Burning Mebium Dynamtie, and Zero uses the Plasma Spark to merge his Zero Sluggers into the Zero Twin Sword and attacks Belial directly with the Plasma Spark Slash. With Belial mortally wounded and out of action, Beryudora collapses and explodes, followed by the Giga Battle Nizer.
- Although Beryudora's subtitle is "100 Monsters", and that Belial claims he is comprised of that many kaiju, Beryudora is comprised of almost all the monsters killed by various Ultras, and he is actually made of over 300 kaiju.
- Beryudora is made up of more monsters than Belial can control with the Giga Battlenizer.
- Beryudora's chilling appearance resembles that of Chernabog from Disney's Fantasia.
- Beryudora is actually a giant puppet that is filmed close up.
