>>26527378The reason I think he could win is because Ash already lost to Alain twice with Greninja. What would losing to Alain a third time accomplish? They can't simply have Greninja lose to Mega Charizard yet again in the league.
Alan also already represents the "older league rival" that Ash usually loses to like Harrison, Tyson, and Tobias...but this time Ash already lost to Alain twice. So I think there's a good chance Ash can beat him.
