(You were walking down the side walk finding someone to battle, and then you saw Brock looking at his Pokè ball)

You came up to him sitting down next to him

You: Hey Brock! You wanna battle?

Brock: he looked up from his ball to you with an excited expression

Brock: Really?! Yea sure lest go!

He held out his Pokè ball which had Onyx in it, he was ready to use Onyx in the battle
