The Avengers: Earth's Mightiest Heroes Wiki

Hugin is one of Asgard's two ravens that serves as eyes and ears of Odin.

It appeared in "Thor The Mighty", when the Frost Giants attacked Asgard getting Thor's attention as Hugin and Munin witnessed it and reported it to Odin.

Later it appeared in "A Day Unlike Any Other", when Hugin and Munin defended the corrupted Yggdrasil from the other Avengers as they were now loyal to Loki.

After Loki's defeat by the Avengers, Hugin and Munin returned their allegiances back to Odin.
