blitz233 wanted to inform that this book is based in the Hoenn region.

This book is completed.

*Spoilers Ahead*

Summary: Wally is a new trainer, beginning his journey to become the Pokemon Champion of Hoenn. He, alongside his Pokemon, go through the Hoenn region. Along the way, they encounter a strange team and things start to get really crazy.
Hoenn needs a hero...And, for some reason, Wally decides he wants to become that hero.

Here's the review portion!

Starting out with the usual: grammar. You have a lot of grammar errors, but that can be fixed with spending more time editing your work. If you take your time and process what you want to write, spelling and fluency will be better, especially in your writing.
Going along with grammar, your story has missing punctuation, such as commas and periods. Even though it isn't completely bad, it still needs a lot of work.

When you write your chapters, they seem extremely short and jumpy. The reason behind this is because you don't put enough details behind your characters, settings, etc. As a reader, they want to see what the characters see--feel what the characters feel. They want to feel a connection to the book their reading in order to get attached to it. In order to fully grasp ideas and content inside a book, you need to be able to place extra detail, let alone detail, behind the words.
A book isn't just words on a paper. It's an art--a philosophy that many don't seem to understand. Writing is a way to grasp onto your imagination and let it soar. Describing words is extremely important when writing a story. If you don't have detail, you'll be confusing the readers.

As for the characters, I was often left confused with transitions with each character. I never knew which characters were which, especially when you added in your own characters into the story. Another thing that left me confused was Wally. Originally, as canon as he can get, his is a coward for almost the entire plot line. He changes to a more confident person close to when the game ends, even then he is still somewhat cowardly.
I have no clue what type of approach you wanted to take, but it wasn't anything close to canon.

Overall, this book needs a lot more work than it's been given. A few things that you could improve on, for this story and other ones in the future, can be something along these tips:

First of all you want to know and understand the plot line of your story before, during, and after writing the book. You want to make sure that information, canon or not, is accurate and appealing. If something that doesn't make sense occurs in the book (which would either leave the readers upset or annoyed), they will most likely leave a few paragraphs into the story.

Second of all, go through the review above and imply any and all of the comments I made above.

The last thing that you can do is re-write this story. I seem to say this in a lot of reviews, but it is true. In order to get the best quality you can get in your writing, you need to re-write everything (or most things). The best way to get better is to improve what you have and make it better.

I'm sorry if I'm offending you when I say this, but I had lost interest in this book by first chapter. I didn't really want to review this, but I wanted to be completely fair with you, as you had asked me to do this.
In the future, though, I would highly suggest to take your time when you write and worry about quality, compared to quality.
