Sigilyph is a multicolored, totem pole-like Pokémon, possessing a single cyan eye on its black head, as well as two similar-looking eyespots (distinguishable as such because they never blink) on its body. Its base is mostly black, with a green zigzag pattern in the middle and a black pattern surrounded by green. Sigilyph has a pair of wings and a long tail-like appendage that are yellow with blue and red stripes on each of the "feathers". It has two black "feet" with three toes each and two small spikes at its base. Sigilyph's psychic powers grant it the ability to levitate constantly.
Sigilyph will use its psychic powers to attack anyone who invades its territory. Due to it retaining memories from when it guarded an ancient city or served as the guardians' emissaries, it apparently flies along the same route constantly. Sigilyph lives in deserts and rocky environments.
Until he met Darkrai and Reuniclus, he had been wandering around Wish Park and searching for friends he could talk to about this world's history and future.
The Sigilyph patrolling the Ruins of Remembrance let out a warning whenever it noticed anything. It must have been guarding those ruins for a very long time.
Multiple wild Sigilyph appeared in White—Victini and Zekrom and Black—Victini and Reshiram. One appeared in the opening sequences of both movies, while the others appeared in a flashback as former residents of the now-relocated Sword of the Vale.
Sigilyph's English category, "Avianoid", may be a combination of avian (pertaining to birds) and -oid (suffix derived from an Ancient Greek word meaning "form" or "likeness"). The name can be taken to mean "bird-like creature".
Origin
Sigilyph appears to have been inspired by the Nazca Lines, specifically the avian figures, and kachina dolls. Like Sigilyph, the Nazca Lines are found in a desert. It also resembles a wind chime or a totem pole; the latter of which is found throughout the United States and Canada.
Name origin
Sigilyph may be a combination of sigil and glyph. It may also draw its name from sylph, a mythological spirit of the air.
Symboler may be a combination of symbol and the agentive suffix -er. It may also involve bora (a type of wind) or Ra (the Ancient Egyptian falcon-headed sun god).
