Unidentified human-like non-oxygen breathing species (Men in Black III)

This unidentified humanoid species is known to resemble Humans, and at least one member was present at MIB headquarters in 1969.

Biology
Members of this species resemble Humans, at least in their faces. However, they are suited to an environment very distinct from Earth, and thus need to wear pressure suits containing their unknown native atmosphere from their unknown home planet while on Earth or similar worlds.

Society and culture
Almost nothing is known about the society of this species. They have opened up travel to Earth, or at least know of Earth's status as a neutral zone, and of the Men in Black.

Technology
This species has been known to use technologically advanced pressure suits for off-world travel, resembling some designs of classic retro-sci-fi space suits. These suits are known to be silvery, with a fishbowl-like helmet sporting an antennae presumably meant for communication. In addition, they have a box-shaped device strapped to their chests, presumably to regulate life support functions, and the wearer is also equipped with a grey snoopy cap. The gloves of the suit oddly resembles mittens, with no distinct fingers, and it is unknown if this reflects the actual build of their hands.

History
At an unknown point in time prior to 1969, this species developed fairly advanced technology, and learned of Earth. At least one member of this species arrived on Earth in 1969 for an unknown reason, and was present in MIB headquarters when Agent J, a time-traveling MIB agent from 2012, was taken in for questioning. J spotted him talking with another MIB agent, who appeared to be profiling the alien and his purpose on Earth. It is unknown what disguise, if any, was used by the alien on Earth, or where he was assigned.
