Wood

Yes, finally a good view of him: youtu.be/sXJJ1pC1jiU?t=30s

Ladies and germs, meet, OOROTTO. A new Pokemon seen in the shadows in various X/Y trailers. It's based on a tree, and hopefully, unlike the last contestant to be paired with Woodman (Sudowoodoo) is an actual GRASS type. As a matter of fact, this one appears to be a Grass/Ghost Pokemon. That's a new type combo, and a cool one at that.

With a spooky looking pokemon paired with on the toughest bosses of Megaman 2, this team is a nightmare from the woods. Latley I've been adding black, crooked shadows to my drawings cuz I'm in a shattered, demented mood at the moment, what 'chall think?

Woodman (Capcom)
Oorotto, or... Rotwood (GameFreak)

Edit:  His official name is Trevenant, very awesome
