Well, the reason I suggested the change in personality was because in order to enter the Gold Tribe, it doesn't just mean to be a very strong Pokemon. You have to have the determination and commitment to go along with it. Very few Pokemon would die to protect something (not including family or loved ones). It's an honorable road, but also a self-sacrificial one.
Anywaays, on to your SU. Ah, Allen. An interesting choice, but I guess I'll roll with it. I would like to point out, however, that the next time you meet him (or any Sentinel), it won't be easy as in the SU to defeat them. Some may call it godmodding, but I'm the GM, deal with it. xD
Although quite a bit of your history is dialogue, I'm willing to go with that. Still, your length is good enough, but I'm not sure enough detail was put into what you've been doing all this time and such. Like, more about your background, and such. Bah, alright, I guess I'll just make you do it in your first post. You're basically accepted.
Please don't post yet, as I have to figure out where I'm going to put you in the story, as I hate it when new RPers just waltz in out of nowhere right in the middle of the action. (always hated that in other RPs).
When I figure something out, I'll send you a PM telling you where you'll come in. If you've actually been following the storyline and reading the posts, you can give me a suggestion via PM if you have one. If you haven't read through the posts I encourage you to. If you don't want to (I know, its quite a bit), I'll summarize via PM when I figure out where you'll be coming in from.
