>>58191016>Pokemon MasterIt's a meaningless, self-imposed title that was only used in the main series back when those games were localized while the ashnime was still mainstream.
The Pokemon Master is a self appointed goal, Ash confirms this to Pikachu in his last episode where he states that becoming a Champion isn't in and of itself his goal, but rather, a Pokemon Master is someone who can befriend any Pokemon in the world (which also ties into his title as "The boy who loves Pokemon more than anyone in the world" which is commonly featured as a sort of tag-line in many Japanese openings but is absent from the localization).
And as of yet he believes he hasn't achieved that due to his inability to befriend a Latios that a Pokemon Hunter attempted to capture that grew mistrustful of humans.
It should also be noted the title is in and of itself incredibly vague, so much so, TCP actually refuse to answer questions relating to what a Pokemon Master is supposed to be.
Now if we change the question to whether or not he's a good CHAMPION? Considering he's outright fucking worshiped in Alola, he's definitely a good one in the region itself and always gives his people a good show whenever he goes back there.
As a World Champion he doesn't have as much of a presence, though he does occasionally get sighted and swarmed by people, but it can be argued Leon was a better face for the title as well as casual battler considering Ash's Corphish got it's shit pushed in by Misty after the supposed big win. A World Champ should be level grinding
