>SM137: Undefeated Emperor Guzma!

>It's the second match of the semifinals. Scizor suddenly had to battle due to Guzma's partner Pokémon Golisopod's "Emergency Exit" activating, and it ended up losing to Torracat, making Guzma indignant with rage over Golisopod's tendency to do as it pleases. And even though Guzma has been in the lead so far, he gradually loses his pace as he sees his old rival Kukui in Ash's forthright eyes.

>Ash vs Gladion, written by the same guy who wrote Ash vs Hau

So Guzma gets cucked by Emergency Exit again and his Bug/Steel type loses to Ash's Fire type.

And since the Meltan evolution doesn't happen against Guzma, Gladion is probably the one getting cucked by Melmetal.
