Seeing the Meltan stack up on top of each other to use Flash Cannon really gave me flashbacks to the episode with Ash's Roggenrola.
Also fun fact: you can see the logo of OLM, Inc, the company that animates this anime, on one of James' bottlecaps.
Other highlights include: James' Bakugou face when he confronted the Meltan, Mimikyu clearly not giving a crap and putting as much effort in the battle as I do in my day-to-day life, and the weird spinny thing the Meltan did at the end. I know that's a reference to some sort of thing, but the name escapes me completely.
Also, hi, Muk. It's been awhile. Was it in the Kanto episodes?
Side note: monkey wrenches are apparently still called monkey wrenches in the world of Pokemon. Come on, live up to your title. At least call it a Mankey wrench.
