Pictures of the starters revealed!:
The region's name is Isshu (????) and is located very far away.
The main characters are older than ever before; they are not children.
The Pokemon's names are Tsutaaja (?????), Pokabu (???), and Mijumaru (?????). For Tsuutaaja, "tsuta" means "ivy" and "ja" is one way of saying the word "snake." For Pokabu, the name could derive from "po" for "pork," "ka" from the Japanese kanji for "fire," and "bu" is the sound a pig makes in Japanese culture (here it's "oink"). As for Mijumaru, "mijuku" means "immature" and "maru" means "round" or "ball."
It appears the starters are an ivy snake, a fire pig, and a sea otter.
The city shown in the top-left of the scan is Hiun City.
Zoroark's ability is called Illusion (???????). The ability allows it to take on the appearance of other Pokemon.
Two new attacks are Trickery (????), which outputs damage depending on the opposing Pokemon's stats, and Claw Sharpen (????), which raises your Attack and Accuracy.
If you trade over the shiny Entei, Suicune, or Raikou from the the Ruler of Illusions: Zoroark movie ticket preorders, you can battle and capture a Level 25 Zoroark. During the battle, the Monster Fox Pokemon will take on the appearance of the Pokemon you traded over, and at several points it will revert to its original form (probably when weak). When it does, you can attempt to capture it.
