As usual, Pikachu got its own Gigantamax just like its own Z-move to defeat Mother Beast, because it is the franchise mascot.
And yeah, Pikachu is surely not used by its own transformation yet, being too bulky and slow that it had to hold its tail to do Iron tail and its Thunderbolt looks delayed, even though those moves are much more powerful under the form.
As expected, Leon won the battle. Even if the continuity is still there with Ash winning the Alola League, Ash is really clueless about Dynamax and the Galar culture, so the outcome makes sense.
Anyways, decent episode. Not so much as a fan of Ash & Pikachu even though the latter own Gigantamax was unique.
