"Meet Hilbert/Hilda, the Trainer some claim to be the strongest of all!"
Before battle (first round)
"Everything can be understood through Pokémon battles! Let's go!"
Before battle (second round)
"Words are the source of all misunderstanding! Everything can be understood through Pokémon battles! Let's go!"
