EP155: Forest Grumps (2001, dub airing) - Great filler episode where the gang and TR are forced to flee for their lives when they run across an Ursaring.

BW034: Gotta Catch A Roggenrola (2011, original Japanese airing) - One I don't remember much at all asides from Ash catching a Roggenrola.

BW064: Explorers of the Hero's Ruin (2012, dub airing) - A pretty enjoyable episode made all the more entertaining thanks to Cedric Juniper. Love Stuart Zagnit in the role as well.

XY122: A Real Icebreaker (2016, original Japanese airing) - The second part of Ash's gym battle with Wulfric and a great one which made it seem like Greninja was destined for greatness... well at least until Alain thought that light was too bright and thus put the flames out on it during the Kalos league.

SM012: The Sun, The Scare, the Secret Lair (2017, dub airing) - The one where Team Rocket actually somehow managed to beat Ash. Also aired in the UK a day before the US as an extra Brucie bonus.

SM109: A Grand Debut (2019, iTunes store release of the dub) - Ash's last Grand Trial and not a very good one either with the episode cramming too much in and an underwhelming battle against Hapu.

SM124: Living on the Cutting Edge (2019, original Japanese airing) - Was never a fan of most of the Ultra Guardian stuff in Sun & Moon but this was probably one of the better ones though still not without it's problems such as the pointless appearances by Deoxys and Rayquaza.

HZ009: Arrival in Paldea (2023, original Japanese airing) - Only Horizons episode as of now that aired on my B-day and a great introduction to Paldea where Liko stops by to meet her father though it seems he wants her back home.

Funnily enough, mostly Sun & Moon episodes with absoutley nought from Kanto, Johto, Hoenn, Sinnoh or Journeys.
