I believe after winning the League the trainer is opted a choice on whether he/she wishes to challenge the Elite Four and Champion. As its been seen, you don't even need to defeat the League to challenge them anyway, considering Ash has battled against Bertha (but lost) and Paul has also battled against Cynthia (and also lost).Yeah, I was talking about if it was Ash and Paul in the Finals. They have been bigging Ash up to beat Paul by the amount of defeats he's had at the hands of him, but I just don't see him winning the league. It would be fun and a nice change if he did, but then comes the aftermath of what happens after you win the league. Elite Four? Face the champion? Something entirely new schemed up in the anime universe?
Although the way this series has gone on, it's quite probable he'll win a league so I'm probably utterly and entirely wrong and that 6:45am isn't a nice time to be thinking.
Also on the topic of a female partner challenging in gyms, I'd actually like a female rival. Not a goody nice rival who they make the best of friends, but a Gary, Silver-esque female rival who kicks ass without a second glance.
As for Ash's battle against Paul in the League, I say it'll come down to a one on one match with them. I think it'll be Ash's Infernape against Paul's Torterra. Even though, Ash will have the advantage, Paul's Torterra was his first Pokémon and therefore is his strongest; leaving the battle to be quite epic. However, I'm still in the direction towards Ash defeating Paul. I'm just unclear whether Ash will win the Sinnoh League or not, as it is possible.
Hmm, Misty as Ash's rival in the 5th Generation? It's an interesting idea to ponder about, but I don't think the writers would choose to make such a decision. If Misty is to ever come back, then it'll be as a traveling partner once more. However, it's likely that Misty's return may never come to be seen, other than given cameos. As for a female rival - one who is head up and strong, I think I could go for that. I wouldn't mind Paul going over to the next generation too, but hey a little switch like that for Ash could be a nice change.You're right. Maybe she could be Ash's rival??? That could be better than them traveling together! She'd make a great rival for him! We could see her get jealous of the fifth gen girl!
