Hmm. That's interesting. Here's what I've gathered from that...
I'm now even more sure that the pokemon bug thing is a bug, grass or bug/grass. But it might not be, I can't predict stuff, as much as it seems like it at times. They sort of look like a bug-reptile thing. Perhaps a new type 'reptile' or something will come, but its not likely. Lol.
They look like they have some sort of gem pattern thing on their back I think. Well that's what I could see in the video. They also remind me a bit of a single celled organism, for some reason. And towards the end, this new thing is letting out a burst of energy or something? Or maybe it's evolved form? I can't tell...
Chespin is glowing??? I take it that the men in white lab coats are scientists. What have they done to that chespin? :O
As for what I've taken in from the scans, hoopa looks like its pulling out its other form in that portal (can I called it that?). And it's pulling something else out. I'm too lazy to try an figure what it is, though. Or its 'sucking' it into the portal?
