On and off, I've tinkered with a character named Sigrid Tordenkopf, aka "Thunderhead, the Daughter of Thor"...of course, who hasn't made their own variation of the God of Thunder at some point or another?
Anyway, research for this character revealed an actual daughter (I forget her name, but she was a valkyrie known for her purity and chastity), as well as two sons, Magni and Modi, Gods of Strength and Berzerkers respectively. Info on them has proven to be sparse, aside from a story where we discover that Magi, at 3 years old, was already STRONGER THAN THE ENTIRE NORSE PANTHEON COMBINED, Thor included.
Sounds like prime superhero material to me, no?
While doing these revamps, I realized I have a distinct lack of male heroes, so I tapped the Thor boys and gave them Thunderhead's old origin: tired of being seen as nothing more than "Thor's sons," Magni and Modi decided to make like the previous Norse gods and go slumming on Midgard (that'sn Earth to us mortals)...I imagine it's akin to spending a wild weekend in Tijuana for gods, so dad gave them a horn to summon Bifrost when they were ready to return and told them to "have fun, nudge-nudge, wink-wink"...hey, they ARE immortal Vikings, what's a little of the ol' R-and-P to them, huh?
...of course, being teenagers (give or take a few centuries), they promptly lose the horn shortly after arrival as it's stolen by a goblin disguised as a homeless man who, cackling with glee about "finally going home!" summons the Rainbow bridge and strands the brothers on Earth.
No chance THAT will come back to haunt them, will it?
While both are prime "tights and fights" material, I decided to try focusing on Magni instead of Modi to start because if there's one thing modern comics has plenty of, it's berzerkers. I figger an immortal teenage Viking would be a handful in and of himself, but if he was Hercules level at 3, I imagine a lifetime of trying to keep from folding people in half or knocking over mead halls by accident would have mellowed him out a bit further than most Norse gods would be...and discovering other teenagers with "powers and abilities far beyond those of mortal men" would at least give him someone to relate to.
I'm uncertain of the uniform, but it IS a first attempt at the character (and by far not the only thing wrong with the pic). Old timers might recognize his symbol as the old "Project Wildheart" symbol upside-down. It seemed suitable.
