User blog:Justin Holland/Ash in Galar theory

I feel that the Galar League will not only have Ash and everything he knows tested in the most grueling ways due to its competitive nature and grow in ways genuinely worthy of the champion he will be but also put everything he has learned throughout the series, including old tactics like Counter Shield and move combos, to good use.

His performance in the Alola League (hopefully with him in first and his performance against Masked Royal Kukui), and by extension, his rising past exploits, will gain Leon and the Galar leadership's attention and either Leon or a Galar representative will personally invite Ash to the League. When Ash first gets there, a disaster occurs with Ash being the one who quells it, XYZ/DP style. Which in turn will gain Marine and Bede's attention, leading to his first galar rival double battle which ends in a draw.

How about a semi-solo traveling Ash (Marine and others would join and leave at different points in the series) with rotating both his new and old pokemon throughout the series, like in Battle Frontier.

Ash will truly become renown, and his past, present, and future exploits will garner some sponsor support as he traverses Galar.
