Paldea has the opposite problem with Kalos. Kalos's gym leaders all have pokemon from Kalos as their ace, when an old pokemon capable of Mega Evolving would have worked better, Korrina being the prime example because even though she has two Lucarios, she uses none of them in her gym battle and instead opts for Hawlucha.
Even the anime agrees to an extent, by giving Wulfric a mega-evolving Abomasnow.
Paldean gym leaders, however, all have Paldea pokemon that fit them to a tee that end up being pushed aside for an old mon that has to terrastalize to match them.
Good luck trying to convince me Mismagius fits Iono better than Bellibolt. I'll forgive Larry for ignoring Dudunsparce since Staraptor is basically a substitute for his Flamigo in his elite four battle.
