Someone who favors ONLY the original generation of pokemon. These people are oblivious, or even annoyed of the newer pokemon generations.

An idiot who hates any Pokémon Games made after Yellow, without giving any actual reason. Genwunners continuously voice their opinion in the jerkiest way possible, while refusing to accept the fact that normal people have their own opinions.
Genwunner: How can you stand White?
Normal person: It's actually really good, you should try...
Genwunner: No, you idiot!

A slur used by kids for those of us who grew up with the true 151 pokemon.
"Fennekin is a great pokemon!"

"Are you high? They ran out of ideas five games ago."

"Whatever, genwunner."

Types of Pokefan who only praise gen 1 games and anime.(Occasionally Up to Gen 2). A lots of people in this section claims Pokémon has gone decline since 2003,while it’s still a massive franchise with large fan base.

Most of the top definition of Pokémon in urban dictionary is written by these people,so it can give a person a biased opinion about Pokémon.
Genwunner:True Pokemon games were Pokémon Red,Green,Blue and Yellow.
Normal Pokefan:What a nostalgia-yard Genwunner.Move on with it.

A term given to Pokémon "fans" who only enjoy the original games in the series. Many of them were kids in the late 90's and grew up playing Pokémon Red, Blue, and Yellow Versions on the classic Gameboy (as I did). However, their negative reputation comes from their constant, idiotic criticism of the brilliant innovations made by more recent games in the franchise, particularly the new Pokémon themselves. Some Genwunners have even gone so far as to deny the existence of these Pokémon, maintaining that the original 151 are "the only ones that count". They also often complain that the designs of the new Pokémon "aren't as creative." A single look at some of the newer Pokémon makes it easy to recognize that a solar moth deity, flying gargoyle-shaped scorpion, and an antimatter-controlling basilisk might just be a bit more interesting to some people than a pile of sludge and some eggs. Basically, Genwunners are just biased, nostalgic idiots who can't understand that things need to change in order to progress, and that children growing up these days might see things differently.
Sensible Pokémon Fan: "Hey, did you see the new Mewtwo forme? I can't wait for Pokémon X and Y!"

Genwunner: "WHAT?! How DARE they desecrate my childhood! They've turned my precious Mewtwo into an alien! This is EXACTLY why these games have been going downhill. They should have just stopped after the original three. Anything that comes after is SHIT."

Sensible Pokémon Fan: "Are you kidding me? You're saying that something is bad just because YOU didn't grow up with it? Grow a fucking brain. Every Generation of Pokémon is great!"

A word to describe people who only like the first and sometimes the second generation of pokemon. They hate every pokemon after those gens and claim the first two gens are the best. They usually try to defend their opinion by saying the original designs are awesome, even though some pokemon in the first generation look bad.
genwunner: omg the new pokeon games suck, there's a garbage bag pokemon and an icecream pokemon.

friend: but the original pokemon had a pokeball that evolves into a bigger pokeball, eggs, a pile of ooze...

genwunner: screw you they are the best and original!

friend: *sigh* whatever...
