Buzzkill

David's Yanmega (Deividdo's Megayanma), nicknamed Buzzkill, is the fourth Pokemon caught by David in the Sinnoh region. He caught it as a Yanma in the Great Marsh. Yanmega is very goofy, often playing around with the other Pokemon in David's party. It has decent power, but it isn't a huge powerhouse at first until it begins to develop and get stronger along the way.

History
Buzzkill is very useful in Pokeathlon's, especially during the Speed courses where it pretty much bests all of its competition. It wasn't used very often as David's journies through Sinnoh progressed, unfortunately.

Following his journies through Sinnoh, David dropped off Buzzkill and the rest of his Pokemon at his house, starting with a clean slate for his travels through Unova.
