*GASP* You have Cirrus' approval. If only you knew how much that meant. Well your roleplay sample is beyond great, I can clearly determine your roleplaying abilities. One little thing though, fix up your grammar a bit. Other than that, everything checks out a-okay. [Besides the fact Aggresive isn't a nature. xD]
Now, your character won't be getting a Pokedex I'm sad to say. It just wouldn't fit in the story, he'll be a regular trainer striving to be the League Champ. He'll be traveling either solo, or with another trainer [I'm talking with another person to see if he's interested] so I'll let you know as soon as I know. :3 You will post REGULARLY, so you'll be a main character! Congrats! :D He won't be traveling with the main three cast, but like I said he'll be traveling with the other trainer if he's interested. If not, he'll be solo but his background has him prepared for it.
So ANYWAYS, I'm sure you figured this out already BUT: ACCEPTED! ^__^
