Ah, I haven't posted a review in a while. Might as well try my hand at this then. I have a few nitpicks before I start going into the story itself:
'It' is improper pronoun usage, as the preceding noun 'winds' is plural and not singular. 'It' should be 'they.'
This one is a Marowak.
And why is a Marowak in Ilex Forest anyway? They're typically in rocky, mountainous habitats that include caves. It could have been Rock Tunnel, which is where Cubone are commonly found.
'In keen sight' doesn't make sense here. Take it out.
The last bolded is a bit funky. At first I thought she ran into a car of some sorts, but that would be kinda stupid if it's blocking her view, which implies that she saw it. 'Banged' sounds weird too - 'ran into' sounds better.
Also, Aggron aren't native to Johto, so the Pokemon choice is weird as well as the fact that Aggron aren't even native in forests.
Also, the battle wasn't really described particularly well. A lot of things just happened, which meant that you listed a lot of attacks. There wasn't much description or imagery. You should try adding in some thoughts or imagery to make the battle seem more interesting.
At this point, I think I've reached my limit. There are a lot of things that just don't make sense, and it doesn't seem like you thought all the way through for this. Even more, the wording gets awkward, and some words aren't even particularly necessary, so you should cut down on a few things. Additionally, your constant use of similes with other Pokemon doesn't provide that much of a description, and it's sort of moot once you consider that the Pokemon making the comparisons shouldn't have that much experience with the Pokemon you want to compare. Besides, you should be trying to describe Pokemon yourself. The similes sort of make everything unclear and even more hazy, because they don't show your interpretation of Pokemon at all.
The battles were really short and simply a series of attacks. There isn't much description there either. You should add more imagery and emotions, especially with the Cubone fighting off the Aggron for revenge. Actually, more descriptions or more words dedicated to the emotions would have helped me feel more for this story, but at the moment I feel nothing. It just reads as a revenge story while there is so much more potential.
