This is a 4-part question...
Which is your favorite pokemon of each generation (currently... not 6)
Which pokemon do you think is the most popular from each generation? (which you think most people would say was his or her favorite, this can be the same as your favorite, but that pokemon will only get 1 vote, not 2)
Which is your least favorite of each generation?
Which do you think is the least popular from each generation?
This is meant to be based only on design, and not gameplay mechanics... so saying Magikarp because he's weak isn't what I'm hoping for.
I'm going to try to pick the top 2 liked and top 2 least liked from each generation for a top 20 sort of thing.
You can pick any pokemon, not just fully evolved ones. If some pick Pikachu and others pick Raichu, both will get a score for their family tree to be in the top 20, but the one with the most individual votes will be the one to represent. (let's say 31 people pick mew, 30 pick lapras, 20 pick pikachu, and 22 pick raichu... The top two of gen 1 would be Mew and Raichu, make sense?)
