From Bulbapedia, the community-driven Pokémon encyclopedia.
Time for a little clean-up, this page is a little old. Once upon a time I predicted that the official English name for ドラピオン would be Drapion. I believed this so strongly that I signed up with the user name "Drapion", and It turns out that I was right. Also, once upon a time, I broke into the Top 20 contributors. Back when I made most of those edits, there were a lot of problems with this site, and for the most part, the drop off in my contributions is due to the drop off in me finding things that bother me enough to change.
His name's still Drapion! Woo-hoo!
