It’s really up to the artist/rper/ectra to determine what the personalities are going to be like. Himaruya has only done the colors and slight body language alteration. It’s the fans that are making them all new people. Nothing is really canon from Himaruya in regaurds to personality. If you want me to search for a specific 2P fandom personality I can just ask for the character and I will locate the art for them.
It’s open ended, you can have fun with it.
Also I am sorry for the later reply I am having some computer issues, my personal computer is away for repair and my library’s computers didn’t like tumblr (it’s a conspiracy!) Right now it’s working. Again sorry about the later reply.
