Notice ash isn’t there. Because he would absolutely clap mr World champ

Which show title is may from?

I would say Iris.

Is the only champion here

Was the Nr 7 on the ranking in the Masters 8

Was able to take 2 of Cynthia's Pokemon >Gastrodon + Milotic (Cynthia was in the Masters 8 the nr 2 of the ranking. And Iris was close from winning. Both were on their last Pokemon. Its unfourtunate for Iris that Cynthia had Garchomp's Mega stone and she had no Mega Stone/Z-Crystsl/Dynamax. If she had it could be possible)

Bonnie has a ZYGARDE
