Have the stampede of Dynamax Regiggas be the catalyst for the conflict
- Dynamax Regiggas stampeding causes the Galarian birds to flee from Crown Tundra (animated version of that tree scene from the games) and they arrive at Mew's Island
- Calyrex arrives as well to get the heroes to solve this crisis and factor in its own plot
- We have a dynamax battle with Regiggas debuting G max Urshifu, Inteleon, Cinderace, Blastoise and Venusaur (Tokio's)
- In the end Calyrex's psychic energy causes them to properly locate Mew, and also it being grass/psychic like Celebi causes Tokio to have interest in it
This is how ill structure
Ep1: Expedition starts, at the island, run into trouble thanks to the stampeding galarian birds which they stop by Goh catching G. Zapdos, Tokio G. Articuno and Gary G. Moltres. Calyrex appears at the end
Ep2: They realise the stampede is caused by Dynamax Reggigas awakening, and he is now arriving to their island. They decide to help as technically their actions caused it by helping Calyrex bond with his two horses, as Reggigas arrives
Ep3: G-Max battle with Reggiggas, ep ends with all the regis being released as they have sufficient information and want to appease Regiggas, and Calyrex departs for it's duties now that it's strengthened, helping give them the psychic energy they needed to locate Mew
Ep4: We get a kinda adaptation of the faraway island side quest from the games, with them being on a Mew chase, when they finally locate Mew, Hodaka reveals his true colours and tries to forcefully capture Mew causing the final conflict, ep ends on a cliffhanger
Ep5: Hodaka is defeated, Tsurugi and Asahi help and Mewtwo makes an appearance to tie into its episode and bring it full circle, Goh finally catches Mew but releases it knowing the dangers/ Mew's free-spirited nature, ends with them parting ways as the expedtion is over
This way, we get the debuts of some important Galar mons, its a fun filled climatic arc to end the series and we get some fulfilled plotlines
