Blue. hes the original. Plus hes in Gen 2. in that cave or whatever. and damn did he whip my butt the first time. I had just beat the elite four and i had that "Im god! The champion of the land!" mentality we all used to get when we were younger after beating the league. He took a lot of grinding to just barely scrape by him. I just wish i could have gone in that cave and beat him repeatedly. The main rival in Gen 2 was that "im so superior and your weak" guy, who i always swept with my typlosion. Wally was more of like a guy who aspired to be you i felt. May/brendan was just kinda.. there? lolz no offense. i cant even remember battling the rival in pearl. As for Gen 5. Bianca was a softy. More like a friend who wanted an occasional battle, she was nice sure. But i want a rival i feel compelled to demolish, and with Bianca i kinda just wanted to protect her, which is what you did most the game. Cheren was kinda lame. Someone said he had good caracter develupment? how? All he did was ask why he wasnt as strong as you. (The reason is because im the best. like no one ever was). I feel as if "N" was a better rival than Cheren or Bianca, and he's not even listed. He's not a true rival, sure, but he felt like more of a challenge and rival figure than the other two.
