Valkyrie

Valkyrie is a Marvel Comics character who appeared in The Avengers: Earth's Mightiest Heroes, voiced by Colleen O'Shaughnessey, and will appear in Thor: Rganarok, played by Tessa Thompson. As her name indicates, she is the head of the Valkyries in Asgard, and a good friend of Thor, often helping him and the rest of the Avengers defeat the forces of evil. Valkyrie is a feminist, and thus advocates equal treatment for women and encourages women to stand up for themselves.
