Believe it or not but back when i had all the pokemon games up to crystal. I once beat either gold or silver entirely with just a Machamp (named Yang), and Alakazam(named Yin). it was unnecessarily hard but i felt good doing it so i suppose that's important.

recently while waiting for Pokemon heart gold to come in the mail (fucking sundays) i remembered the fond memories and creepy fantasies of that team and decided to draw them from then i first traded them over from red to the last time i used them to beat ash in mount silver lol.

so that's there story and yes the two sequels will have them in there evolved formes. heh
