Ash, Leon and others in “Meeting Up with the Monarch!”

Hey Leon, what's it like to be a Champion, anyways?

[a bit glum] I'm scared all the time.

Huh?

I've never lost a Pokémon battle before. And that scares me a lot. I'm scared I reached my limit and I can't grow anymore, that I can't get any stronger than I am now. [cut to a flashback of the Darkest Day arc] But when that happened...

[flashback] The sky!

[flashback] Could that be Eternatus?

[continuing the narration] I tried, but I couldn't put a scratch on Eternatus. [goes back to the present] I was frustrated but excited at the same time. There are still many in this world that are much stronger than I am. But, I'm still chasing after them! I've got a lot of work to do to grow stronger!
