Strider: Spider King
A Grass/Ghost would be fun. Hopefully it is the evolved form of the Pumpkin Pokemon rumor that we heard about a while ago--even though Pumpkins aren't trees. I could see a lot of use for a tall Grass/Ghost perhaps you can shake trees in a forest and it actually be one of the Pokemon in question.
That'd be cool. Like a better version of headbutt.
