So, I'm writing a story about a group of superheroes, and all of the heroes have codenames based on different mythical gods and goddesses (ex., the stealth-based one is Nyx, the flying one is Horus, etc.). I'm having trouble figuring out two, however, those being one character whose signature ability is using heavy melee weapons like warhammers, and one who can shapeshift into a fox.
I know I want their names to derive from Earth gods and goddesses, not ones from fictional mythologies. For the hammer guy, the only two things I could think of were Ares (for the fighting aspect) or Hephaestus (for the hammer part) but I don't think either fit with the character or what he would choose. For the fox one, the closest I could get was Loki, since foxes are generally seen as tricksters, though Loki is more associated with snakes, so that doesn't really fit either.
