Before Johto

After Ash's battle with Gary, he went back home and told his mom about his plan to go to the Johto Region.
"I understand Ash." She smiled. "So I wish you luck on your journey and make sure to look after yourself and Tomo." 
Misty and Brock wanted to go to the Johto Region with Ash and Tomo as well.
"I want to catch water type Pokemon from that region." Misty said.
"Yeah and I would like to catch some Johto Pokemon from there too. Especially some new rock type Pokemon for my family's gym." Brock said.
"Are you going with us?" Ash asked Tracey.
"No." Tracey responded. 
"I'm going to stay here and become Prof. Oak's assistant." He explained.
Ash and the others nodded; Tracey did admire Prof. Oak after all.
When Ash and the others met up with Prof. Oak again he was trying to study the GS Ball.
"Any luck professor?" Ash asked. 
"I'm afraid not." Prof. Oak sighed. "Not a single computer of mine can analyze this."
"Wow, this GS Ball is more mysterious than I expected." Ash said.
"But there is someone in Johto who might be able to uncover the mysteries about the GS Ball." Prof. Oak said.
Prof. Oak explained that in the Johto Region, in a town called Azalea Town lives a man named Kurt. 
"Kurt is a man famous for designing special Poke Balls." Prof. Oak said. "So if anyone can figure out the GS Ball, he can."
"Can you take the GS Ball to Kurt?" Prof. Oak asked Ash.
Ash agreed to take the GS Ball to him and put it in his bag.
"Oh Prof. Oak there is one more thing I would like to do." Ash said. 
He informed the professor that he wasn't going to bring his current Pokemon to Johto as he wanted to capture Pokemon native to that region. Prof. Oak liked that idea.
"I can't wait to find out what Johto Pokemon you catch." He said. He also gave Ash a new Pokedex.
"This Pokedex is from the Johto Region." He explained. "And it has all you need to know about the Pokemon that live there."
"Thanks professor." Ash said.
The next day Ash and the others got ready to leave for the Johto Region. Ash and Tomo were wearing different outfits. Ash was wearing a white shirt with a black and blue jacket and dark blue jeans. The only things he kept on were his hat, sneakers and gloves. Tomo was wearing grey trousers with a white t-shirt and grey trainers. Delia, Prof. Oak and Tracey went to see them off.
"Well I hope you all enjoy your journey in the Johto Region." Prof. Oak said. "And Ash, I wish you luck in the Johto League."
After all the goodbyes and best of luck, the gang set off to Johto for new adventures.
