As far as the knew evolutions go, they don't mean that much to me since I havent used any of their previous forms in years.
Tangrowth - Never liked Tangela, but when I was younger I would hear about how underneath the vines no one knew what it looked like and I always tried to draw what I thought it would look like.
Electivire - Always kinda liked Electabuzz, but more as a lesser pokemon. It was somewhere in the middle, but Electrivire looks awesome and had it come out earlier it probably would have the electric spot on my personal team (Luxray has that spot)
Porygon-Z - Never cared much for any Porygon (so much so in fact that I called it Polygon through all of generation 1, pesky text skimming), but I was always intruiged by the concept. Also if it was created how come another pokemon hasnt been created in the same manner, and shouldnt it have tons of evolutions from adapting itself to cyberspace viruses and such? and what about his ability to fly into space? wouldnt you think with all the rumors that pokemon came from space that someone would have mobilized an army of these guys to search for some? but all that is off topic...
Glaceon - even though I dreamed this up back in gen 1 I don't care for it but I like the design.
Leafeon - same as Glaceon, thought it up years ago but this one looks a lot better
Magmortar - This one is just awesome. It has the best concept of any of these. The sheer fact it has a megaman like cannon makes it awesome. I'll never use it unless I play through soulsilver using pokemon I other than what I usually do.
Magnezone - It needed to have a better form than just 3 magnemites. I hated how they had pokemon that just came together and evolved (other than slopoke) Other than that though its just another # to catch. Maybe diglet will get one someday.
Rhyperior - I guess I always wanted an evolution of this line, but not this one. It looks like a Rhydon ate a grenade or fell into a volcano. With all that said I am coming around to it but it is still a blemish to rhyhorn (now that I think about it I hated Rhydon too back in the day. Guess I just like the rocky look of Rhyhorn)
Lickilicky - Well not much to say. Never cared enough to even remember lickitung was a pokemon ( when I first saw lickilicky I thought "hey that looks familiar. is it a new evolution? nope, it cant be since i know all pokemon and I cant think of another that looks like this one)
In other words out of all of these I would only ever use Magmortar and Electrivire in any form of my personal party with Rhyperior and Magnezone being close but still stuck in a box in favor of another. I'll always collect the eeveelutions. And as for the rest, give it a few more generations and ill forget them like lickitung
