>>39567865In my Ultra Moon playthrough, I used a Golisopod with a Quiet nature, which given its species I took to mean cowardice. I tried to have a Golisopod battle with Guzma and got forced out by his First Impression, so I decided my Golisopod's goal would be to win that mirror match. I trained him up with Proteins and in the Aether Paradise fight, I lost the duel again. I led Golisopod in Ultra Necrozma and the Elite Four and envisioned his epic training montage atop Mount Lanakila.
Finally, when my second Title Defense battle was against Guzma, I led Golisopod against his, outsped it and forced it into Emergency Exit with my First Impression. That was the battle when he proved his prowess to his enemies and to himself, becoming the strongest of his species in the entire region.
Even though it's just two pokemon exchanging attacks, it felt like the culmination of a deeply held rivalry and made the victory that much more meaningful.
