(Annoying trope) Unnecessary explanation for fantasy name
Mistborn- Spook's original name, Lestibournes, originates from in-universe slang "lefting I'm born"
Solo: A Star Wars Story- The most well-known example of this, when the Imperial officer put Han's last name down as Solo because he always alone
The Dark Crystal- Gelfling comes from the Aughrian "ghelflainnk" meaning "one who lives without knowledge of the future", though granted this isn't in the actual movie
Black Panther: Wakanda Forever- Namor is derived from "el niño sin amor" (the boy without love)
