In "Star Trek", Klingons are commonly referred to as "Black Elves".

The statement that in Star Trek, Klingons are commonly referred to as black elves is false. In the Star Trek universe, Klingons are a species known for their distinctive forehead ridges and aggressive and honorable warrior culture.

This statement appears to be a misinterpretation or confusion with other fictional works or inaccurate portrayals of Klingons in popular culture.
