I decided to put in my favorite quotes. Most of them are Pokemon quotes.
Ok, fine. All of them are Pokemon quotes.
1.

Trainer N, also known as Natural Harmonia Gropius, has a lot of inspirational quotes. It's amazing, and also hard to choose a favorite.

2.

Alder is the champion of the Unova region, and he, like all the other champions, help you slightly in the game.

3.

This is a Mystery Dungeon quote, and I think Grovyle has a point XD

4.

Another Trainer N quote. This ones even better in my opinion.

5.

This isn't cannon, but I still like it, because it describes all the protagonists in the games. Because, even though they become champion in the end, they're all just average kids. The youngest of them was probably Red when he started his journey, actually. He was ten. And now, he's thirty, if you count the years since the start of Pokemon.

6.

This isn't a quote, but I found it interesting.
Actually, imagine if that happened to someone, where the Master Ball failed XD

7.

No truer words could have been said, Meowth.
I love this quote. Meowth from Mystery Dungeon has a point; everyone is the same in the end. We're all human. We're all living, breathing, things with feelings. And you know what? Those who don't realize this are idiots.

8.

This quote by Mewtwo from the first Pokemon Movie is definitely my favorite. It's true, it's beautiful, and it's all around us.
It doesn't matter who are parent were. It doesn't matter what we look like. It doesn't matter what our religion is.
What matters is what we choose to do with our lives. You can be whoever and whatever you want to be as long as you set your mind to it.
Let's just hope you want to be one of the good guys and not someone with bad intentions.
