You forgot about the champion of the region

that's because the champion was gonna be my first OC. His Pokemon are insanely powerful too.
SAFer123's Pokemon:
1: Gholdengo & Samurott-No Gimmicks (They will be working together in the same party slot)
2: Miraidon-No Gimmicks
3: Floette-Mega Evolution
4: Arceus-Z Moves
5: Galarian Articuno-Dynamax
6: Poliwrath-Terastalization

How tf are you supposed to beat that monster without a full lvl 100 team? I'm genuinely curious

That's the crazy part, they're all level 100. but the final boss will be him using all his Pokemon in a boss rush situation where you'll need to work with your rivals & the Elite 4 since he already captured the Gym Leaders (Similar to the Rouge Mega Pokemon in ZA)

aight I'm calling Volo, I might be cooked

Not even Volo can save you

Wait, have you even played Legends Arceus

Yes, Volo was hard, but I beat him & Giratina

image how hard volo would with a fkn mega zygade that also had 3 health bars?

I'd use Poliwrath
