It was a good episode but I'm disappointed Torracat evolved. I've never been a fan of Incineroar's design and its overuse in media. I dislike when quadruped Pokémon change into a bipedal design when it doesn't fit the design of the previous ones. Vice versa as well, Samurott being an example.
The battle was great, I love the use of dual Inferno Overdrives and both Pokémon jumping into the flanes while the Ash-Greninja theme played.
I still consider Lycanroc being Ash's ace for this region due to the fact that it accomplished so much more during its run. Torracat only really had this single rivalry and while it was important, Torracat lacked in other areas.
I did finally get something I really wanted though. A Lucario appeared and its wasn't the writer's pet. We had enough of that species after Riley, Maylene, Cameron, Korrina, and the movie one.
Naganadel did fairly well against a Pokémon with a type advantage against it. We already saw Meltan tank Mareani's Sludge Bomb so idk why we needed the same scenario with Lucario. Why was that move X-Scissor when it could have easily been Fell Stinger? It mist have been so weird for Pikachu to hear Ash command a Thunderbolt when it wasn't him using it.
At least the series is basically over, we won't really get to see Incineroar in action. Unlike May's Blaziken, this one's not a pity.
