Appearance
Loki was considered a runt for a frost Giant, but made an Asgardian because of his father altering his appearance when Loki was found as a child. He used to have red eyes and blue skin. However, when Odin altered his appearance, Loki now had green eyes and black hair.

Notably, his wardrobe consists of dark colours, most notably black, green and dark blue
