Asio in Owlboy: The Mentor Owl
Who Asio is in Owlboy, his role as an elder owl mentor to Otus, and how he shapes the story of the Owl Temple and the Ancient Owls.

Who is Asio in Owlboy?

Asio is Otus's mentor and the protector of Vellie in Owlboy. He is a supporting character in the game, and he is presented as a grumpy, no-nonsense old man who gives Otus the owl cloak he wears throughout the game.
He is also closely tied to the game's backstory. Notes collected on the Owlboy community wiki point out that both Asio and Otus are named after the scientific name for the long-eared owl, and a hologram in the Eternal Sanctuary shows an owl who looks similar to Asio, probably his ancestor, doubting the theory of The Loop.
What does Asio look like?
Asio is an owl with a long green shirt, red cuffs, black pants tucked into knee-high brown boots, and two long yellow feather-like feelers above his eyes. His black-and-white owl cloak is worn on his back and gives him the ability to fly, according to the Owlboy community wiki.
What is Asio's relationship with Otus?
Asio is Otus's strict mentor, and the two have a tense relationship. The community wiki describes him as strict and cold toward Otus, showing dislike of him in every in-game interaction; it says he does not trust Otus to do a good job and often reprimands him.
He gave Otus the owl cloak during Otus's studies. Things come to a head in Advent, where Asio locks Otus inside a building so he "wouldn't do anything stupid," and the wiki notes Asio only realized his mistake after he endangered Otus there. He then spends days brooding at the lookout point in Vellie by himself.
How does Asio fit into the story of Owlboy?
Asio is the protector of Vellie, and he fights alongside the Advent Guard. According to the Owlboy community wiki, Asio, The Professor, Strix, Fib and Bonacci assisted the Advent Guard in defending the city during the Battle of Advent.
He also appears in one of the game's achievements. The achievement Good Boy carries the description "Tried to report to Asio at the first sign of trouble," as the achievements list records.
Does Asio have any connection to The Loop?
Yes, at least implicitly. The game ends with a silhouette of Asio, or perhaps Asio's ancestor, which the community wiki reads as implying that The Loop is the end of the world.
That reading comes from fan documentation rather than an official explanation, so treat it as interpretation rather than confirmed lore. For the game itself, see the Steam store page.
