-Terapagos: fairy/dragon in both forms, 3rd form is a special tera form "Anti-type"
-Koraidon and miraidon have an anti-type form similar to ogerpon tera form
-"Anti-type makes pokemon lose their type, but tera blast becomes neutral"

>Dipplin evolution Ceucaddle grass dragon with two snakes coming out of an apple with wings
>"Dokutaro" pokemon is ghost/poison to possess and put people and pokemon in a trance when made physical contact. In battle it becomes an ability where the opponent falls asleep when you make contact
>The "peach" form isnt what it looks like, its similar to zygarde's situation and gimmighoul

>Drayten isnt the only relative to a previous trainer, Crispin is the son of seibold who pursues cooking, but prefers the fire type

>Unova elite 4 makes a cameo once the main story is completed. They can be battled at random in the battle facility in the post game similar to the battle tree in usum and Grimsley makes a comment about how he was surprised his Bisharp evolved after so much time

>There are possessed trainers you need to battle to "free" from the "Dokutaro" pokemon, you collect fragments of it once you save people from it

>Keiran is the champion possessed by "dokutaro" which once you beat him, you have to defeat dokutaro which puts everyone into a trance. Terapagos contains one of the last fragments of "Dokutaro" which then leads to the rest of the story in area zero with you, arven, penny and nemona

You use terapagos to defeat "Dokutaro" similar to the paradise protection battle
>you have to use "Dokutaro"'s abilities against it, and pretty much "posses" it, by making it lose its typing using terapagos

(the paradox legendaries, entei is a stegosaurus, fire/dragon and terrakion looks bulkier like a robot ready for war, rock/psychic)
(previous legendary pokemon can be battled in terrarium in tera crystals as they were "displaced")
