This might get a little confusing. I'm going to be going through all my character and telling a little about each one. They are all from or will be in the on-line comic http://mintwhelp.comicgenesis.com/ made by a friend of mine. This is confusing because there's some time travel involved so in the comics story and Riki isn't actually guardian yet. Plus some stuff I can't write about them since it hasn't happened in the comic yet even though that event could be an important part of a character. (This paragraph will be posted for each character I do so you can ignore it after the first time)

Nix in the Mint Whelp story is currently just a kid. He's yet to be even named in fact. But in the future he is a new breed of Fechi, a professional soldier. As the Fechi migration went on, the lands became dangerous and the Guardian alone couldn't protect everyone, so the Guardian was forced to train soldiers to serve under him. He takes his job seriously and uses a modified Thompson sub machine gun (custom made for Fechi usage). Can't say much about Nix though, none of his story is explained yet so I want to keep it a secret till it appears in the comic.
