Goh Gettem!
I mean, Legends Arceus came out this year and is entirely about catching every pokemon. It's a viable goal. Gotta catch em all.I felt that Goh's purpose was an experiment to see if he could carry on with the anime as the primary new protagonist. However, I felt the writers just didn't know what to do with him, besides incorporating his gimmick of being an expert catcher and wanting dream of catching every pokemon in the world. However, the problem with that goal was once he caught a Pokemon he never or rarely ever used it. Which defeats the purpose of why he was ever considered a Pokemon trainer.
I mean, the writers couldn't place Goh into doing gym challenges or pokemon contest performances as that would make him more so a copy of previous protagonist.
With Ash being the center main protagonist of the story, it seemed that the writers couldn't give Goh a proper goal as a trainer to make stand out mor, besides some mini arc story with Project Mew.
I mean, it begs to question the reason Goh was made out to be trainer. Whats the purpose of being a pokemon trainer if all you do is simply catch Pokemon but never train or use them for a primary purpose such as battling or other competitive competitions such as contest, to bring out their potential and establish a true relationship with them.
