Hereto, you're still fighting Brotad! I left you a VM with the most recent Brotad response. :3
... Yeah, no. Sorry, but you really have to knock it up a few notches for it to be acceptable. You even somehow forgot Team Gaia's name; it's four letters long! If you're using this SU or this SU as an example of what you should try to achieve, please don't.
This SU, however, is a good example of the minimum we're looking for. Also, separated categories.
The appearance is extremely bare. I don't even have the slightest visual of what he's supposed to look like. All I can see right now is a stick figure with anime hair.
The personality needs serious expansion past "he sees good in everything".
I see the history now, and it's completely incongruent with the personality. If he never had friends, and was bullied on a regular basis, and his PARENTS. DIED, why in the world does he have such a /positive/ outlook? If wild Pokémon are what killed his parents, why would he even want one? Just... just no, okay?
I'm sorry, but you'll have to change this SU quite a lot. I honestly don't doubt that you can do it — I think you really can put out a well-made character (that doesn't contradict itself so blatantly) — but as it is now, it's far from being accepted.
I'd also like to suggest that you get a proofreader. If you don't have Microsoft Word, LibreOffice is an absolutely wonderful free alternative.
