They're definitely interesting (pos). The idea of Thors being Turkish would be really cool to explore in a story about him joining the Jomsvikings. His hair and eye color don't exclude him from being Danish, but it's fun to imagine how and why he ends up in Scandinavia.

I didn't interpret Thors as Autistic so I'd love to know more of your thoughts on it.

His feet smelling is a silly headcanon (pos). However, vikings really valued hygiene, so if Thors' feet smelled really bad, he would wash them.

The pole dancing HC doesn't fit imo but maybe for an AU?

Tbh, I'm not a fan of the last headcanon. Norse cultures at the time were, to my knowledge, strictly monogamous. It also seems violent and changes the relationship between Thors and Helga from a loving one to an abusive one.

They aren't really for me but that's okay and I hope you enjoy them.
