re dir said:"In the original Pokémon Red/Blue, when you encounter your rival in Lavender Town he asks whether or not you know what it?s like to have one of your Pokémon die. At this point in the game, he no longer has his Raticate that he used in previous battles. Your rival battle before this took place aboard the S.S. Anne. Your rival?s Raticate sustained serious injuries from the battle? but, because crowding and confusion on the luxury liner, he was unable to make it to a Pokémon Center in time and the Raticate passed away. The real reason your rival is in Lavender Town to begin with is to lay his deceased friend to rest.
Despite all of this, your rival never outwardly tells you that you?re responsible for the death of his Pokémon. He hides his grief and instead channels that energy into the motivation he needed to continue his quest to become Indigo League Champion. The death of his Raticate effectively destroys your rival?s impish, childhood innocence. Although he tells himself that he doesn?t hold you responsible, he subconsciously holds a great deal of resentment towards you which further fuels his ambitions. Tearfully swearing upon his Raticate?s grave to not fail in what he set out to do, he trains hard in hopes of becoming better than you? defeating you? and to eventually make it to the Pokémon League.
Mere moments after he became Indigo League champion, he was defeated? by you. Although he fulfilled his promise to his fallen Pokémon, it was only for a painfully brief instant. In the end, your rival is scolded by his grandfather while you receive the professor?s praise. During the course of the game, you steal your rival?s innocence, crush his dreams, and ultimately snatch away the love of his own grandfather. Oh, and by the way, your rival doesn?t have any parents. He?s an orphan."

Kruxxor said:Also, when you fight your rival, on the SS Anne, I believe, he has a Raticate that he uses in battle, obviously you kick his ass to progress the story. Later he tells you about how he couldn't get his Raticate to the Pokemon Center in time, he doesn't say that it died, but you can guess as much.
In some of the versions of the story it is mentioned that Blue says to red that he couldn't get raticate to the pokemon center in time. This conversation never happens. Here is a rough transcript of your time with blue when you meet him in lavander town's pokemon tower:
He never even mentions his raticate again.Blue before the fight: Hey, red! What brings you here, your pokemon don?t look dead. I can at least make them faint! Let?s go pal!
Blue after the fight: What? You stinker. I took it easy on you too. How?s your pokedex coming pal? I just caught a cubone I can?t find the grown up marrowak yet, I doubt that there are any left. Well, I better get going, I?ve got a lot to accomplish pal! Smell ya later!
There is one more bit of logic to throw into the story. It is said that the reason raticate died is because Gary couldn't get to a pokemon center fast enough. If this is true, why didn't his entire team die? In the game, pokemon in a party are all healed at once. If raticate didn't make it in time, his other party members didn't.
There are plenty of things to insist that pokemon die. The story of cubones skull, Ghost type pokemon, fossils, the marrowak ghost you find in the pokemon tower, but this story isn't one of them.
Mostly because I'm bored
