That's why I'm in Galar right now. i left Behemoth the Zamazenta to deal with her in Paldea because I can't take it anymore. I don't think there is a way to change her.
I lived in galar my entire life, I still live here now. My twin is from Paldea she does visit me at times, also my twin is much weaker than me so she will have to look out for Lilly jr
I need to say that Behemoth's sister is in the Galar region right now. She is annoyed that we have to level up this low level Kubfu just to progress the plot the correct way in the Isle of Armor...
