In Pokemon diamond, who is the person that runs into you in fight area?

Question

In the fight are, there is a blond kid that runs into you and i wanted to know who is he and I would also like to know if you see him again or anything?

Answer 1

Well one of those is your Rival and the other one is blond too and has a green jacket is the Tower Tycoon Palmer and you battle him when you get a 21 win streak on the battle tower. He is your Rival's father.

Answer 2

the blonde kid would be your rival. He appears every weekend (saturday and sunday)

his team never changes (not that I've noticed) so it would be a nice way to level up, gain some EXP, some money, and for the h**l of it, kick his butt.

Answer 3

He's your best friend/rival. How exactly can you not know that cuz he appears through out the WHOLE ENTIRE game!!! And yes he appears again. Hope this helped ^^)
