Final major update for swsh due in early 2022. It would add some of the new hisui mons and missing sinnoh mon but not all

Gigantamax post game side quest in pla. It's heavily implied to take place at the same time as the darkest day event in swsh. You can't gigantamax, but you do have to investigate Pokémon with a "strange energy" that when transferred to swsh have the gmax factor. Some new gmaxes are introduced including gmax dragapult which takes inspiration from an aircraft carrier. It has a cool gmax move that launches off lots of dreepy from the run way
