Dugtrio

Dugtrio is a Ground-type Pokémon and the evolved form of Diglett, born when three mature Digletts fuse together into a single body. Like Diglett, Dugtrio's body size and shape are unknown as only its heads have been witnessed by human eyes.

Pokédex Data
Dugtrio's three heads think the same and act cooperatively. This Pokémon moves extremely fast and is capable of burrowing constantly without ever needing to stop. It can dig to a depth of 60 miles beneath the earth's surface and digs at a speed of 60 mph. It is capable of triggering earthquakes.

Alolan Variant
In Alola, Dugtrio has evolved into a Ground/Steel-type due to the volcanic activity of the region. What really sets them apart from Dugtrio in other regions is the mane of golden hair on each of its heads. One head has a bob-cut, the second has curly "shoulder-length" and the last one has flowing hair that touches the ground behind it. This hair is made out of thin strands of steel and it grows slowly and continuously throughout the Dugtrio's life. The Alolan Dugtrio is regarded as a feminine deity of the earth and taking its hairs are thought to bring bad luck.
