>>33073995It was never said that Red is the most powerful trainer. /vp/ is stupid when it comes to Pokemon, but denying events that happened in both GSC and HGSS is silly. In SM, Green states that he and Red were once champions in their hayday. Such a statement blatantly and clearly implies that he and Red are no longer champions as of SM.
Even if we accept /vp/'s stupid theory about the Kanto quest in GSC and HGSS being non canon, Red would have lost his title to the current champion of Kanto regardless. For all we know, there could have been two or three champions after Red. If we return to Kanto, Red's not going to be the champion.
