Least Favorite Pokemon Rival

[Arjahn]

Silver, or the Gold/Silver rival. He just seemed like a dick with no purpose who complained constantly after stealing an old guy's pokemon. That's just mean, and he never really had any reason to do it other than he felt like it, as opposed to Blue who you had an actual rivalry with, this guy just shows up and fights you sometimes, then blames it on his Pokemon when you beat him.

Also, not sure if it counts, but Wally. Why? Because that asshole got a Ralts on his first wild pokemon encounter ever. Lucky bastard.
