In the north of Verdanturf Town lived a young man who was very passionate about pokemon.
"North" isn't a place, so someone can't live in the north. I think this would work much better worded as, "In the area north of..."
“Hello?” he called through the phone.
You don't need to add "through the phone", as that is already implied by the context of the story. Also, the first quotation mark on just about every dialogue segment looks really weird. It didn't translate here, since your formatting changes didn't transfer, but if you look at your post, you'll see what I mean.
“I am guessing other groups are already aware also and will be making plans for this also,” Ben said.
You said "also" twice, and the entire segment is just awkwardly written. I would recommend revising it.
The first thing I noticed is that your dialogue is a little choppy. In other words, it doesn't quite sound like human speech. Here's what I mean:
“I am guessing other groups are already aware also and will be making plans for this also,” Ben said.
Well, other than being awkwardly worded, there are a few things that tip off the reader. The first, is the apparent lack of contractions. When speaking, most people don't say "I am", but rather shorten it into "I'm". If you want realistic speech, you have to follow the patterns of everyday speech. If you're having trouble with this, try saying it out loud. I can guarantee you're going to struggle with it the first time because I tried saying it out loud, and got about halfway through it before I had to start over. Think about how you would explain it, and use something like that instead. If it's awkward to say, then it's going to be awkward for the reader to read.
The other thing I should touch on is showing v telling. This is arguably the most difficult aspect of writing, and it's something the most experienced writers struggle with from time to time. So, don't be mad or disappointed if you don't get it right away. It takes a lot of practice to get even the basics down. I will once again provide an example:
In the north of Verdanturf Town lived a young man who was very passionate about pokemon. This man was called Ben or to give him his full name, Ben Gallagher.
Ben was a 25 year old working for the Pokemon Protection Squad or PPS for short. His job was to protect any pokemon from unnecessary harm whatever the circumstances may be.
Right now, you're telling us all this information, and I have one word for you, boring. I don't mean to be harsh, but this section could use a bit of spicing up. In order to show, try to think of examples. Instead of telling the reader he likes pokemon, show an example of when he climbs a tree to help a stuck Skitty, or something. It's less about words, and more about examples. Anyone can be friendly, but it's a matter of examples to show the reader how friendly.
Instead of plunging the reader right into the plot, you have to take the time to show the reader their surroundings and let them get their bearings. I'm not talking about describing what's around them (although, that would be nice too), I'm talking about walking your reader through a normal day for the character. Have him help a pokemon, and then call it back to headquarters, or have him march right into headquarters for a monthly agent check, or something. Just don't tell the reader. I can guarantee that the first couple paragraphs could have made up one, two, maybe even three chapters. It's all about letting your reader slide comfortably into your story, instead of dropping a brick of information on their head. Which, I kind of felt that brick in the introduction.
Also, I would give a little more thought about description. Don't describe everything at once, like Fiona's appearance, but rather reveal the information as it becomes relevant. Have Fiona brush her short, blue hair out of her [enter eye color here] eyes. It's that simple. It seems like you're rushing through the description and heading straight into the dialogue. I do the exact same thing, and description is a really hard thing to get down, but keep working at it. I'm sure we'll get the hang of it eventually.
I know I pointed out a lot of negatives, but don't feel bad about it. It just means that there's some stuff to work on. This isn't bad, but there's room for improvement. However, with just a bit of polishing and elbow grease, I guarantee you that the quality of this will skyrocket. The potential is here, there are little glimmers of potential throughout this chapter, I'm just trying to help you reach it. I'm sorry if I sound a bit harsh, but I'm not really one for sugar-coating things. Just keep the things I have said in mind, and I think you'll be surprised with your improvement as you progress with the story. Good job, and I wish you luck with future chapters!
