Otamamon X

Otamamon X is an Amphibian Digimon and carrier of the X-Antibody. Since its body has become even larger, its vocals have become louder, and the effects of its Special Move "Lullaby Bubble" have strengthened. It is said that because of a certain Mutant-type Mega Digimon, it looked forward to a promising future with its round body and was gifted the gorgeous crown "Prince no Osagari" (プリンスのオサガリ) and it became difficult to be attacked by the enemy due to its majestic appearance. Furthermore, it also taught Otamamon its Signature Move "Smiley Headbutt".
