Well done! Your OC is only 20% Mary-Sue/Gary-Stew! That's pretty impressive over all, so you have my congratulations, but... that still makes your OC one fifth Mary-Sue/Gary-Stew. Not a good thing, but not too bad. You should be pleased you've kept well away from the most common Mary-Sue/Gary-Stew traits, just make sure you don't hype them up anymore, or they may well become obnoxious, and frustrating like al those others out there. Nice work! :D
Why not tell me what you got? All you have to do is press that little button, right there. Right down there. You know the one. All input is appreciated! :)
