No trainer, other than your rival, will have a starter Pokemon. Thus, if you have a totodile, and your rival chooses a chikorita, you will never be able to see a cyndaquil through normal game play (e.g., not trading).
your rival is trainer blue
When you first begin your journey, choose chickorita. Then that guy who has red hair and looks like a girl will have a cyndiquil. other than that i cant think of anything......... there are some in platinum...... hope i could help~! yay!
The champion is your rival.

You'll be introduced to him or her.

You actually get to name your rival. So, your rival is whoever you want him to be. The rival is just a strange character that happens to be eying Professor Elm's Pokemon.
