Former traveling companion of Ash Ketchum. Brock was the previous Rock-type gym leader of Pewter City before his younger brother, Forrest, took his place. 

He's a passionate Pokemon Breeder, and quite the man with the ladies with his smooth words.  Unfortunately, they don't really like his persuasive romantic assaults. Besides that flirtatious side we all know and love Brock is rather mature, an excellent cook and knows a lot about Pokemon and many areas and regions.

If you were to travel anywhere, you'd want to bring him along for the ride. He now spends his time back home training to become a Pokemon Doctor.
