Haha, I'm glad I'm not the only one who thinks Wally should get Sceptile.
I'm not going to lie but when I first played Emerald I thought Wally will get the last starter. Not only is it canon for Wally to have Sceptile in the manga but it really fits him. If he ever makes an appearance in a future Pokemon game, I hope he gets one.
Barry didn't really need a better team. He has the best competitive team out of all the rivals iirc, with great moveset coverage and generally moves that match his mons better attack stat. And until the Red revamp, he had the highest overall levels of all trainers in the series iirc
You can't call him out for being wrong when he never intended to be right - Stephen Colbert "Bad Mojo" is not a diagnosis - Dr. Foreman, House, M.D.
