In the Digital Multiverse, you became a Chosen One (all generations included).
What is your model of Digivice and with it, who is your digital partner ?
You may choose an answer that technically has the entire standard evolution chart:
Baby 1 - Baby 2 - Child - Adult - Perfect - Ultimate.
If your option has alternative evolutions, you may also choose, as long as it means a power-up from the basic or previous form.
You are allowed only 1 partner digimon.
Have fun !
