Aah, I forgot he learns that! It's not that I dislike Beedrill, it's that I love Vespiquen to a degree which is almost silly. I traded a MEWTWO for a female Combee, fer chrissake! But yeah, I just love Vespiquen's "order" moves, they're so conceptually cool... summon a swarm of bees to DO MY BIDDING!!! Yes!Just because it looks ugly. *sigh*In 4th gen I'd say replace Sableye with Spiritomb and Beedrill with Vespiquen. Shiftry is an awesome Pokemon, totally underused in my opinion.
But I like my beedrill! MEGA HORN!
EDIT: Hey, Beedrill doesn't learn Megahorn (according to Bulbapedia, anyway)
