Change is good
Constally changing
Too many to choose from but for me it has to be the villains Maxie and Archie because are so much fun to fight, memorable and funny.
Sapphire is where I met Kazami, a level 100 Alakazam currently in my Black2. Sapphire was my first pokemon game (lost it two years ago =3=|) and I've used Kazami in every game onwards as my main partner. One day, I thought I left the game he was in at a restaurant, and I stayed up all night crying. That pokemon has been with me for FIVE YEARS! I found him though. He's safe and sound in my 3DS now. I have owned all the gen IV games and he's beaten the league and entered the hall of fame in every single one. He's like a child to me... ;3;
Replaying this game would mean the world to me. I would probably cry and short it out with my tears because it holds so many memories.... I remember catching it at level 9 in Dewford cave like it was yesterday...
