BigUkkomon is an Ancient Fairy Digimon. It is a Digimon thought to have emerged the very moment that the ancient Digital World was destroyed. It is said to have sacrificed its own life to summon a Digi-Egg from the sadness of the Digimon that disappeared one after another during the great destruction. However, information regarding whether or not this Digimon was able to complete this act does not exist within any records. There are records of the existence of the Mega Digimon known as the Ten Legendary Warriors during the era of the ancient Digital World, but BigUkkomon was also estimated to have possessed an amount of data equivalent to a Mega Digimon. This cannot be verified, however.[2]


  • Violent Punisher: Brandishes an innumerable number of supermassive tentacles to smash and gouge targets over a large area.


BigUkkomon's design is based on the Naked Sea Butterfly (Clione limacina). In its "predatory form", in the center of the funnel-like mouth, there's a figure resembling a Buddha and although it looks like the main body, it's not actually the main body. It's a structure similar to bait, designed to make people think it's the actual body.[3]
