1. I love your art! 2. About your BATIM Digimon AU, since I never really watched it growing up, and you clearly know more than me, what are the basics of Digimon and their relationship with humans? Can two people share one, what happens if a mon is corrupted, can a human own more than one? And other stuff like that.
Digimon and their partnered humans share an emotional bond: the human’s thoughts and feelings lend power to the digimon, and the digimon protects the human. At earlier stages of their relationship (i.e. early episodes of the show) it just takes a rush of adrenaline from the human getting in danger to trigger a temporary power-up. To achieve a Digimon’s most powerful forms, though, involves the human exhibiting true bouts of emotional strength and maturity in the face of adversity. Ideally, a partnership with a Digimon will lead towards a human becoming their best self.
There have been instances of two human partners sharing a digimon and one human having two digimon partners, but usually it’s a one-on-one relationship. (unless you’re in Fusion but that doesn’t count shh)
Corrupted digimon can happen in a variety of ways: a virus shutting down their individual will, an outside force controlling or corrupting them for their own purposes, or a backlash from their partnered human becoming emotionally volatile and becoming their worst self, resulting in twisting the digimon’s form into something volatile and monstrous... to name a few prominent examples.
