It matters about the Digimon, if you pass time it might digivolve to another digimon while some of them digivolve to another digimon if you have like 3 or more battles to make it digivolve. for an example: Greymon will digivolve to MetalGreymon with at least 10 battles, or he'll digivolve to MetalGreymon(Virus) if he has 30 Vaccine AP or he'll digivolve to SkullGreymon if you pass time. understand?
