A dark matter lifeform

A dark matter lifeform is a lifeform composed of dark matter, which dwells outside normal space-time. Federation theoretical physics of the 24th century seemed to preclude the existence of such a lifeform, as molecules so complex would collapse under their own weight.

In 2376, the Delta Flyer encountered a dark matter lifeform during an exploration of a class T cluster. The lifeform at first sheared off a piece of the Flyer's hull, and then transported Crewman William Telfer briefly to its native realm. Telfer was returned with the lifeform inside his body, having taken control of his nervous system and established rudimentary telepathic contact. The lifeform subsequently left Telfer's body and accessed the Flyer's systems, causing Crewman Mortimer Harren to panic and destroy it with a phaser.

Shortly after, more lifeforms advanced on the Delta Flyer seeking retribution. Captain Kathryn Janeway was able to disable them by triggering a chain reaction in the radiogenic rings of a T-class gas giant. (VOY: "Good Shepherd")
