PC's Daughter later changes the color on the DV7's grips to match Exmon, Red, PC's son got his arts and crafts skill from PC he also obtained one of his childhood projects, it was called "Puppy-Head" as it was a robotic head of a puppy, but would go through 3 phases before it would gather all of its data into the form of an egg then vanish, PC's son built it and powered it with his DV7 (That he already made),automaticly linking it to the machine and the DV7 dubbed the machine "Puppymon". There are other DFC's all over the world, but the events of Ultimate take place in Canada. Crimson Blood later in the series got a new Digimon after Cthulhumon was permanatly defeated, Minimon.
