I fish duck

So I'm wondering, should I keep Charlie as the antagonist throughout the whole story or should I get rid of him soon?
          
          He's so rude and I think maybe I should make pj a new antagonist in a few chapters but I'm not sure, maybe Alfi. 
          
          Okay so I don't know who should be the new antagonist if I get rid of Charlie or maybe I should just have Dan and Phil just have internal conflicts with themselves 
          
          Help!
