Okay so lets use our imaginations here for a second and pretend that Pokemon are real. You have yourself a pretty awesome and balanced team, you just beat the Elite 4 and made your rival look like a b!tch in front of his grandpa, when all of a sudden. BAM! Zombies! And they are EVERYWHERE!!You are already a Pokemon master, but does that mean you can be a zombie killin master too? My suggestion to you is to take the trusty bike out of the ol' backpack and make your way down to the nearest unaffected Pokemon Center. Or you could just fly there if you are lazy. Once there, you should go to the PC and withdraw your Scyther! He just has Zombie killer written all over him! With 2 huge blades for hands and the ability to fly, Kabutops aint got nothing on this guy! He will ngle handedly keep you safe against the zombie horde, decapitating random zombified trainers left and right.
Thats my choice for my pokemon zombie killer. Whats yours?
