Brunnhilde (Earth-8311)

Powers & Abilities
Super Strength: Like all Asgardians she has incredible strength.

Healing Factor: She has an incredibly fast healing process, even by Asgardian standards.

Teleportation: Like all Valkyries, Brunnhilde can teleport herself (and newly deceased souls) from wherever she is in the universe to the halls of Valhalla, and then can teleport back to her starting point.

Death Empowerment: If an ally dies in battle, her strength is vastly increased until the battle is over and she takes their soul to Valhalla.

Expert Combatant: She was put through the Valkyrie training process, one of the strictest training programmes in the Ten Realms, and as a result is one of the best fighters in Asgard.

Weapons Expert: Part of her training included learning to use an array of weapons.

Paraphernalia
Dragonfang Sword: The iconic swords of the Valkyries. It is almost indestructible, and is able to cut through any mystical barrier.

Aragorn: Brunnhilde's bow, which enchants any arrow that comes into contact with it, making them able to pierce through almost anything.
 * One of the few things it can't cut through is mystical barriers.
