FUKs are anyone who opposes the rule of King Dedede and The Other Gods. There are not very many FUKs, as they are almost always killed by Sharpy or Ryan. Some friendos used to be FUKs, and some FUKs used to be friendos, but usually when you are a FUK, you stay a FUK forever. The OSC has many FUKs. Some people say Da Quintet might be FUKs, but you're not allowed to say that because the Da Quintet will say YOU are a FUK instead. You FUK.
