Like cockroaches, the indomitable Pokemon will be around well after Fukishima finally explodes in a triumphant, human-obliterating nuclear fireworks show. They will never be defeated — but a bunch of Pokemon enthusiasts will be this weekend at the Pokemon national championships, the final qualifying round before the world championships this August in Hawaii. (Beat that transition!) Admission is free and the competition is open to all U.S. residents “in good standing” — meaning, I suppose, those who have not graduated from Pokemon to a raging Dr. Who fetish. Any upstarts will have to deal with Pokemasters like Ryan Sabelhaus, ranked No. 1 in the world with a rating of 1973.97, and the Indiana-based Dustin Zimmerman, approximately six points behind Sabelhaus in third place.
