Yanma is a large, red dragonfly Pokémon. Compared to its long, thin abdomen, its thorax is short and wide. It has three pairs of two-toed legs and two pairs of wings with red bands on them. A bright green mask marking covers most of its face, and it has two spikes on top of its head. Its blue eyes can see all around its body allowing it to have a high evasiveness. The end of Yanma's tail has two flat extensions from the sides and two gray spikes in the center.
Yanma is a skillful flier. It can make sudden stops, turn in midair and hover in place by flapping its wings at a high speed. It can also generate shock waves capable of breaking glass by flapping its wings very fast. Yanma is often found in wooded and swampy areas. It hunts insects for food, using its eyesight to spot and its flight abilities to pursue prey. Yanma is also territorial, flitting around to guard its territory.

In The Thief That Keeps on Thieving!, Tyler was about to catch a Yanma that his Piplup had weakened when the Team Rocket trio showed up and Jessie caught her instead. They sent her to Giovanni; however, Team Rocket already had obtained a large number of Yanma, and so Giovanni returned her to them. When Jessie used Yanma in battle, she used Ancient Power and evolved into a Yanmega.
In Wings n' Things, Zachary Evans owns a Yanma. Unable to control its wings' sonic abilities, it was breaking all glass in town, so Zachary reluctantly abandoned it. Yanma was then captured by Team Rocket and used for one of their schemes, but Zachary rescued it and had it blast the trio off.

In the TCG
Yanma seems to be based on a dragonfly, possibly the banded darter. Because of its size and weight, it might have been inspired by prehistoric ancestors to modern dragonflies and damselflies in the Meganeura genus, commonly referred to as "griffinflies". This is further supported by its evolution, Yanmega, which is much more closely linked to ancient dragonflies, and whose offspring did not have a larval stage, instead hatching directly into a smaller version of their adult phase, as Yanma is a fully formed dragonfly.
Yanma and Yanyanma derive from 蜻蜓 yanma (large dragonfly).
