What are some good Warrior Cats Kittypet/Loner/Rogue names?

I'm working on a fan fiction, and these cats are NOT going to be in a clan WHATSOEVER. I need more Kittypet-type names than loner or rogue. So, names like uh... Boulder or Raven or something like that... Maybe even Mr.Fluffykins, but that's kind of overdoing it. Thanks!
