I dont know about another character that might be overloading it a little bit. I mean 3 is a crowd but 4 is like a party! And since Dawn has 2 rivals and ash has paul then thats alot now i think. I do think they should do something a little different with brock though!! I just can't see Ash winning a league though. You know what!! I think should happen in this league!! Ash meet up with Richie and battle in like the top 4 or something and have richie win!! I think that would be really cool!!
