Modi Thorson (Earth-139)

Modi Thorson, known as the God of Wrath, is one of the Princes of Asgard, and a hero across the Nine Realms of Yggdrasil.

Powers & Abilities
Spiritual Resurrection: Most Asgardians are reincarnated in Midgard upon their death, but Modi is one of the very few who isn't. Instead, his spirit is absorbed into his hammer, Svartvedir, which then finds somebody it deems worthy, and if they agree to it, merges Modi's spirit with theirs. Each time this happens, he takes on some of the person's physical and personality traits, as well as retaining their memories.

Sorcery: From an early age he showed innate magical abilities. Under Freyja's tutelage, he learned how to master the mystical arts, and can perform all varieties of spells and rituals.

Expert Combatant: He was trained by the Berserkers of Asgard in their combat techniques. While he relies more often on weapons, he can still handle himself in a fight.

Weapons Expert: Modi is trained in the use of a range of different weapons. He chose a hammer to be the 'spiritual successor' to his father's weapon, but is able to wield just about any weapon, from a knife to a gun.

Paraphernalia
"Whosever holds this hammer, should they have the just wrath of Modi, shall possess his spirit"

Svartvedir ("Black Storm"): Modi's hammer, forged by Eitri of Nidavellir, allows him to channel his magic into powerful surges of energy. In combat, this can be used for powerful strikes against his enemies, and also allows it to be used as a conduit for mystical rituals. Due to it's magic-channeling properties, it is one of only two weapons on Asgard (the other being Heimdall's sword) that can summon the power of the Bifrost.
 * The weapons of Modi and his brother, Magni each contain a fragment of Mjolnir, recovered after it was shattered, which allows them to release bolts of lightning when on the verge of death.
 * Should worst come to worst and Modi dies, Svartvedir will find somebody it deems worthy and, should they accept, merge Modi's spirit with theirs.

Trivia

 * In Norse Mythology, Thor's sons Modi and Magni inherit Mjolnir after his death. I loosely adapted that idea into Mjolnir being the one that's dead, and the weapons they wield containing a part of it.
 * The idea that Modi's essence is transferred from person to person is kind of like the concept of regenerating in 'Doctor Who', with his appearance and personality changing with each incarnation.
