ALEX has heterochromia, which is when one eye is a different colour form the other, in Alex's case one eye is dark brown and one pale amber eye. Alex's hair is dark at the roots but dyed green. Alex also has a tiny symbol of Loki tattooed on their nape. Magnus noted that Alex's physical appearance didn't not change when they swapped gender, apart from a few subtle differences.
