#having a legendary be a bad influence would be refreshing and also takes legitimate resentment a character builds for yours makes it worse

Thinking, putting pieces together...

Leaks about Dokutaro (aka the Poison Peach) who granted the Loyal Three their deepest wishes (to become stronger/wiser/prettier) by fixing them with the toxic chain...

Kieran vowing to become stronger and rumored to be the Champion in the Blueberry Academy arc...

Codes for 'zombie' in the DLC that haven't aired for the Teal Mask...

What I'm wondering if the player is asked to come to Blueberry Academy to help defeat the 'Champion' because they have taken control of the school and made everyone into 'zombies' with toxic chains - all part of Dokutaro's master plan (which may involve Ogrepon, may involve Terapagos) and you, as the main character, have to fight your way through the school and the 'Elite Four' to get to Kieran and free him from Dokutaro's influence. I also think that perhaps the evolution for Dipplin might go from Grass/Dragon to Poison/Dragon (to keep with the theme of caduceus and healing but the opposite, and also tying in with what happens to Pokemon influenced by Dokutaro - wouldn't be surprised if a new poison-move boosting item is introduced as well).

I know there's theories that the professor wearing a scarlet blazer and violet pants might be the villain (and she might still be involved, maybe she releases Dokutaro and introduces Kieran to it in a bid to get Terapagos) but thinking about how the first half of the DLC is more exploration and the latter half is battling makes me think about the Team Star battle mechanics but also how to raise the stakes and what makes sense story and lore wise given everything that's being set up.

Then again, maybe I'm wrong. This is just speculation after all...
