Pikachu and then Lucario are the two most popular and iconic pokemon period end of discussion
I really don't know about that. At all. Most people my age that I know (28) only played the first pokemon game as a kid. Also this is my personal experience.. but I play in a videogame cover band called Kirby's Dream Band..and we all dress in pink with Kirby's face on our T-Shirts and pink short shorts. I remember during Comic-Con we had a show and I was walking around in my outfit and I shit you not, 70% of the people called out "Jiggly Puff!" to me. Not even kirby.. Jiggly Puff!
