What does it mean when a pet evolves incorrectly?

My name is Lin Chen. I transmigrated to the world of Digimon, and was preparing to work hard to become a legendary Digimon Tamer when the system insisted that I was a chosen child, hoping I would save this world from collapse. As the only savior, Lin Chen decided to let this world experience the fear of being dominated by Digimon! ... My name is Su Qingyuan. Every month, I have the same dream. A nightmare that foretells the future. Two years later, the apocalypse arrives, and a dark crisis engulfs the world. In the face of despair, a Digimon beast tears through the sky, saving all people. It is covered in black gold armor, its head is majestic, its back is covered with a metal shield, its arms have dragon claws like blazing blades, and its posture is as upright as a war god. She must find the Digimon Tamer of this beast and end this dark crisis ahead of time.
