What was your pokemon "WOW!" momemt? It could be about anything. Like a pokemon that keeps using protect 5 times in a row.
When i went to Red in my hg, me and him were down to our last pokemon. he had a level 86 charizard with a little less than half of his hp, and i had a level 16 kangashkan that i use as a hm slave.
I use quick-attack and barely hurt hit. Then he uses fire blitz and knocks me out.
I was about to turn my ds off when the recoil KOs the charizard! And I won!
