Onega Town Museum
"Hey you! This is no place for kids! Get lost, now! ... ... ... No, you say? Fine! Athena! Deal with this impudent child."

"Hmm... ... ... no matter! We have what we came for! The Time Caller! You have proven you are a threat to our cause. Watch as we catch a legendary Pokémon and become unstoppable!"

Onega Town
"Since you defeated my assistant, you've proven yourself worthy to watch Team Olympus' rise to power! Sableye, use the Time Caller! ''

"It's Shaymin! Amazing! The Time Caller was succesful in calling Shaymin from another time! Now go, Master Ball! Excellent! Shaymin is ours! The legendary Pokémon of purity! Soon, the most powerful Pokémon in the world will belong to us, and we will be unstoppable! Now stay out of our way, or next time I may not react so mercifully!"

Mt. Press
"So... You've come at last. I've been expecting you. [Player name], is it? You've caused a lot of trouble for me. You've stopped my plans, defeated my commanders and now you're trying to stop me... And you know what? I accept your challenge. When I defeat you, the power of my victory will cause Victini to awaken! Give me your energy, [Player name]! Let us awaken the sleeping god!"

"Impossible! I lost! My victory was supposed to generate the energy to awaken Victini and- What was...what was that? I don't like the looks of this... Could it be? It's Victini! Can... can this mean? Victini was awakened when you earned your victory over me... Since you proved yourself a victor... you are the only one that can catch Victini. Even I will not mess with the rules of the world. Go... go do what I was unable to do... Catch Victini!"

''You... you...You actually caught it... Every time! Every damn time!"''
