Okay, so I have a friend who has the resources that allowed him to obtain images of the entire Kalos Dex (but not the Mega Pokemon), basically little shots of them in-game along with their name, number, and typing. He did not send me the pictures when he first obtained this info, since he can't take that risk, but did share with me the list of them alongside their Typings, as well as a brief description. A bit later on, I met him in person, and finally got to see them for myself...he said that I could post the full list and my own impressions of them, as long as I didn't give away any names or info beyond that. So, well, here is the list I typed up based on what I saw, and the information he shared with me. I have a decent memory, but some of the more detailed ones I don't quite recall everything about them, so they might not look exactly like I described them, but the Typings should all match-up as well as the evolution lines.

Because the list I typed up is quite lengthy, I created a paste-bin for it:
