Otamamon is a Child-level Digimon that resembles a large tadpole. It has an indigo-coloured, ovoid body ending in a short tail with a fin, two arms ending in three clawed digits and two underdeveloped legs. It has circular eyes and a wide mouth filled with short fangs.
Otamamon resides in lakes and rivers upstream of the Net Ocean. When it swims, it uses its legs as rudders. It will occasionally climb up onto rocks with its developed forelimbs and do vocal training.
Otamamon shows clear signs of its upcoming digivolution and is prone to mutations, resulting in a large number of potential forms it could take. These qualities make it highly prized among Digimon Trainers and Tamers.

X-Antibody[]

When imbued with the X-Antibody, Otamamon's body balloons to comical proportions. Its arms become stubby and its hind legs atrophy away while its tail grows longer. It sports a crown atop its body and gold cuffs on its forearms.
In this state, Otamamon is more resilient against attacks, but its own attack power is weak and it has fewer moves. It retains its Lullaby Bubble attack and also resorts to striking enemies with its Smiley Headbutt. Its smile never fades while it is attacking.
