Melony and Zamazenta were the reasons I chose shield. I hate Avery and Allister. Despite Zacian having better attack stats, I prefer Zamazenta's design and I'm not a smogon player. I'm sure modders will one day mod Avery and Allister out of the game.
I don’t want to be rude but, Melony is probably the weakest opponents in Pokemon Shield, I always complain and always say “I really wish Gordie was in Pokemon Shield!” So that is why I don’t like Gym Leader Melony.
