Name | Casey "Azelf" DeRuiter
Okay, first off, let me just ask: could you make your SU longer, in general? It's incredibly short in every section. You may want to take a look at some of the other sign-ups to get some ideas.
Also, you might want to start with correcting your grammatical errors. Proper nouns, such as names of places, people, pokemon, and even moves should be capitalized. You also spelled Misdreavus wrong. And dialogue, such as in your writing sample, should begin a new paragraph when a new person begins speaking.
Onto your character himself.
First, why do people call him Azelf? Is it because of his necklace? Why was Azelf significant enough for his friend to make a necklace of it in the first place?
If you want to make his appearance longer (which I suggest you do), you might want to consider things such as build, skin tone, hair length, height, weight, and perhaps some more superficial details such as the shape and size of his facial features, whether he has any odd marks on him, or how well kept he keeps himself and his hygiene.
Personality-wise, what exactly makes Casey a "friendly guy"? And why does someone being from Lavender Town make them odd? Besides, wouldn't most of the people he knows be from Lavender Town as well? Why is he shy? And if he's afraid of being left alone, why exactly would he want to go on a pokémon journey alone? (Suggestion: perhaps to conquer that fear?) As far as making it longer . . . perhaps add in some quirks, more general likes and dislikes, how he behaves around certain people (because everyone behaves differently around different people) and whatnot.
The History section should be longer than the other sections, so keep that in mind.
Why does he, specifically, protect the tower? I'm sure the town would manage it, considering it's essentially a large, highly regarded cemetery. What "invasive species" of pokémon would be troubling the tower, anyways? And that's really all you've put in your history, since the other two sentences focus on his parents. What was his childhood like? What experiences has he gone through, and how have they shaped him into the person he is today? Also, keep in mind that
not just anyone can be invited to the Lost Islands League. They need to have proven themselves somehow, either through displaying their prowess in raising pokémon, or by getting an important individual, like a professor, to notice their potential.
As for your writing sample, once you separate the dialogue into separate paragraphs and fix the grammatical errors, all you should have to do is expand it (substantially) and then it should be acceptable. Work on the other sections first, since they'll probably give you an idea of what to do with this once they're expanded/completed.
Again, I suggest looking at some other SUs to get an idea of what to do. You don't have to make yours exactly like them, or necessarily as long as them. Just make it acceptable.
