This app has been denied for several reasons, but these are the biggest:
You have El listed as "Unique" but you never explain what she is, or how she got to be that way. You have a handful of powers but never explain how she got them or how they work. The history for the character was all over the place, making mentions to characters, organizations, etc. that we have no idea what they are since you never really say.
Over all, it would take more effort to correct this application than it would to simply start over with a whole new idea. So, while we are denying this character, we welcome you to try again with a different character more in tune with the SPN 'verse.
