Zygarde’s various forms are used as Ride Pokemon - but you can only use the 10% form in battle before the post game. All of them are Dragon/Ground type. Aanungamir is vaguely antagonistic. AZ’s Floette is in the game. A character calls it an “Ascendant form” and compares it to an “Ursaluna found on a faraway island”, so i guess those are a thing now. No new regional forms - the only ones that show up are Galarian Zigzagoon, Paldean Wooper, and Alolan Raichu.
