Arcadiamon (Ultra) is a Bewitching Beast Digimon. The form taken when Arcadiamon (Mega) evolved even further when it absorbed energy generated from battles. Capable of rocking the ecosystem of the Digital World, its sheer power makes it known as being exceeding Mega.
- God Matrix: An unblockable attack that instantly dismantles anything and everything into ones and zeroes with invisible waves.
- Dystopia Lances: Absorbs data from Digimon and attack energy with just a touch of its countless feelers.
Arcadiamon (Ultra) in particular, was based on a jellyfish. Ten'ya Yabuno was "scrambling" for ideas for it, and wound up seeing a news report about the Nomura's jellyfish, which lead to him designing the Ultra form after it. Its body was designed to be shell covered like a tortoise. Yabuno also considered a humanoid form like UlforceVeedramon, though after submitting both designs was told to use whichever he wanted, leading him to combine both designs together.
Arcadiamon's design may also come from the concept of the archdevil, as well as a play on the programming term.
Arcadiamon (Ultra) was designed by Ten'ya Yabuno.
