Opossummon is a Beast Digimon. It armor-digivolved due to the "Digi-Egg of Kindness". Its cute looks and trademark colorful balloons make it seem like a Puppet Digimon from a fairy-tale village, but when angered, it attacks by spreading around balloons charged with powerful computer viruses, and then detonating them. It's fond of dry, sandy soil, and usually hides under the sand with only its balloons showing above. It hops and bounces through the air when flying, and still keeps a tight hold on its balloons when on the ground. It's an annoying fellow that isn't able to move very fast, but that doesn't mean it's easy to catch.
- Mad Balloon Bombs (Mad Balloon Bomb): A terrifying technique that breeds powerful computer viruses in the balloons it holds in its hand, bursting them as they lightly float over the enemy's head during battle.
- Mystery Hat (Mystery Orb)
Opposumon is a black, stubby furred opossum with a white face and green eyes wearing large red gloves, boots, and cap. It carries balloons in its right hand that enable it to float around.
