I am glad that you like it! I actually have the sprites for everyone except Sloane made up so when it comes up I will post their sprited so you can see what they look like. As for generations and such, I felt there needed to be sort of a class system since every person's DNA is different, meaning they can only tolerant certain DNA implants. Plus, you have to think about it. When this first started, they weren't just instantly able to fuse an Arceus' DNA into a person. They had to start small and work their way up. That's why there are different generations with different restrictions and strengths. As for natures and characteristics, because they have Pokemon DNA in them, I felt it was understandable that they would share as many qualities as possible with these pokemon, which included natures and characteristics. While the natures and characteristics don't usually reflect the individual, they do reflect something else that may become more clear in the next chapter or so.

Just as an update I am working on the next chapter but I do plan for it to be a much larger chapter. Currently I am debating whether I want to split the events into more than one chapter or not. So what is your opinion? Would you prefer quicker but shorter updates or longer but slower updates?
