Ah, you timed your arrival well. I've just finished reading a book, you see. Allow me to introduce myself. I am Lucian. I am a user of the Psychic-type. I must say, you've already proven yourself to be outstanding by coming this far. They say I am the toughest of the Elite Four. I'm afraid I will have to go all out against you to live up to that reputation.

Hmm... Now what should I do...

I see. You getting past the three before me was no fluke. Your power is real. Congratulations. You have beaten the Elite Four. However, that doesn't mean you're done with the Pokémon league. There remains the Champion. I should warn you—the Champion is far stronger than the Elite Four. Now, go on. Step through the doorway to your final battle.
