"The choice is yours, Klara," stated Saisei, "You can pick either one of us to battle against or you can retract your challenge. Either way, your friend knows what the two of us are capable of."
"He knows he is," Shiranui interjected, "I'm Shiranui Tsukiko, Sea Hero of the Whirl Islands and Champion of the Kanto and Kalos Leagues." He sent out his most powerful partner: Saisei the Mewtwo. "If you truly wish to take on the most powerful Pokémon, I'm right here," stated Saisei.
Shiranui saw the Wailord as well. "It still amazes me that not even Christa lying on their side can compare to the length of a Wailord," he stated, referring to Chuck's Celesteela. He knew of Wailord's extraordinary compatibility with some of the smallest Pokémon, but didn't want to mention that in public.
