Samurian

The only named member of this species is Mikey who is seen in Men in Black voiced by John Alexander.

Other members of Mikey's species appears briefly in the first M.I.B Headquarters scene of men in black (although it has multiple eyes, a tail and is quadruped in a canine-like posture) and also in the first episode of Men in Black: The Series, "The Long Goodbye Syndrome".

A member of this species with female voice is in Will Smith's song Men in Black, it appears in the music video, dancing with Smith's Agent J. The strange thing is even though the voice is female it is believed to be Mikey but there are two good reasons why this unlikely if not impossible 1. it is obviously not voiced by John Alexander and 2. by the time Will Smith's Agent J joined men in black, Mikey was already dead.
