Men in Black reports come in two varieties: deathly pale and with robotic/unnatural speech, and olive/brown skinned with funny accent.

The former race is the Tall Whites. They come from somewhere in the vicinity of Gemini and have a culture based around family and learning. They seem scary but are quite benevolent once you get to know them. The reports of them practicing slavery is an act of slander on the part of the reptilians. The olive-toned ones with a Graeco-Roman culture and customs (the accented ones that sound like Spaniards and look like Greeks) are from Tau Ceti. They visit warm tropical areas due to it feeling the most like their homeworld and are said to be descended from various captured ancient humans from Earth crossed with an indigenous species, resulting in a hybrid race that has pointed ears. As a result, certain sources say they inspired the Vulcans from Star Trek.
