Enchantress as the main villain, but with the Wrecking crew as middle-bads. Enchantress drops a bunch of Asgardian weapons on Earth, and maybe they hurt the people Thor cares about. Seeing the damage even the least threatening mortals can do when they have such powerful weapons makes Thor distrust other mortals who have powerful weapons as their own.

It's also a good reason for Thor to leave Asgard for Earth, which is the most important narrative hurdle in his movies.
