Yanmega, the Ogre Darner Pokémon. When it flutters its wings, it creates a shockwave that can cause internal damage to its opponents.
– Dawn’s Pokedex
Yanmega is a huge dragonfly, being almost 2meters (6’3″) tall. It’s based on the giant prehistoric dragonfly. I saw a lot of big dragonflies during my trip to the cottage up north, and thought of Yanmega.
It’s one of the new Gen IV evolutions, having to evolve by Yanma learning Ancient Power, because Yanmega is based on a prehistoric animal. But it’s 4x weak to Rock. In Gen IV, Yanmega is one of the few Pokemon that can learn all 3 variations of Ancient Power (attacks with base 60 power, special, and has a chance to raise all stats by one stage): Ancient Power (level up), Silver Wind (TM or breed), and Ominous Wind (move tutor). Although in Gen V, Silver Wind is no longer a TM, and there is no move tutor, so it can’t learn Ominous Wind anymore.
In the anime, Jessie has a Yanmega, which she used in contests as well as in battle. It was discovered to be female when a female Togepi tried to use Attract, and it wasn’t affected. It seems smaller in the anime than its Pokedex size.
Stat-wise, it has good Sp Attack, even though for some reason, it gives 2 Attack EVs; it also has decent Speed, which is good to combine with one of its abilities, Speed Boost. Its other ability, Tinted Lens, is also a pretty good ability.
