First Bird Pokémon
Archen is a Rock / Flying-type Pokémon, No. 566 in the National Pokédex, introduced in Generation 5 (Unova region).
« Archen is said to be the ancestor of bird Pokémon. It lived in treetops, eating berries and bug Pokémon. »
A small bipedal Pokémon, both reptile and bird. Its large red head is scaled, with blue and red neck feathers, untidy sallow plumage, and blue wings that end in claws.
Extinct and revived from a fossil, it evolves into Archeops. Its wings are too small to fly: it hops from branch to branch and glides long distances to snatch prey.
A female revived by Fennel and Professor Juniper evolves into Archeops before its debut episode ends.
The design is based on Archaeopteryx, a dinosaur long thought to be the earliest bird. Archen may combine Archaeopteryx and Archean, a geological eon.
