Drapion has a variety of powerful Poison- and Dark-type moves at his command, but with the help of the Move Relearner and a few Heart Scales, can also learn all of the new elemental Fang moves. Drapion's unique type combination protects him from most of his component types' weaknesses, with the exception of ground attacks. This makes learning Ice Fang essential, as Ice attacks are strong against Ground Pokémon. Powerful and cool-looking, Drapion is sure to be popular in the future.
