Lanturn. Great unique typing, but its stats can't back it up. Rotom doesn't count.
+1 to all of this.
Of the options listed, though, I'm going to go with Pinsir. I don't like it nearly as much as I like Tropius or Absol (or really anything else of that list), but Pinsir does need it more and does deserve it after putting up with so many generations of being total crap. Plus, I could see its design as having potential to evolve into something really cool. --- My NIDOKING brings all the boys to the yard: http://goo.gl/ExAoe
Not really sure where this list came from... but uh, I don't get why some of these are in the list. Namely Absol, Ditto, and Sableye.
Nitpicking aside, my vote would go toward Dunsparce probably. It has the potential to become a decent snake... but it REALLY needs to be a Normal/Ground type or something. --- Shadow Temple... Here is gathered Hyrule's bloody history of greed and hatred... - Shadow Temple Walls
^ exactly my thoughts... they didn't make the cut, but Absol and Ditto did. xD No offense toward the TC or anything. I'm just nitpicky. ;_; --- Shadow Temple... Here is gathered Hyrule's bloody history of greed and hatred... - Shadow Temple Walls
