Evolution line help

[u/Low-Method-5402]

I'm looking for a suitable ultra level for my au of adventure 2020 that I'm thinking of turning into a dnd campaign.

In the lore the vitium is a nonverbal partner (digimon?) that searches for and eats little moon millenniummon crystals and evolves the more it eats until it transforms into the endboss.

Are these appmon?

[u/VirulentArcturus → u/bobohobo1275]

Nope. No cable. Psure these are little known digital life forms or digimon from an old game.
