you walked to Goldenrod city.You always wanted to visit this place and..and you finally visit it!But you bumped into a red-haired boy..who was shorter than you "Hey!Watch you step,moron." He made a 'tsk' sound ...seems you angered him.And he look like he will give you a hit by his Pokémon..but you decided to just move pass by.. "HEY!NOT SO FAST,IDIOT!" he yelled,holding a pokeball..oh no.You need to do a Pokémon battle with him,or he will chase you
