Even most dragonball sites consider Tien to be a human, he just has a third eye, Krillin has no nose, so does that make him not human? I read it some where that he aquired his third eye, I have to get ready for class so I am not going to look it up. Regardless of that Tien is still a human, if he isnt a human then Krillin is not either. Having something extra just makes you a mutant. I would like to know where Krillins nose went.
