Seraphim

Seraphim are shapeshifters. However, unlike familiar shapeshifters like the Dominion Founders, the Seraphim have more limited abilities. They seem to only be able to shapeshift within a limited range of mass, roughly no more than 100kg. At one point, the Seraphim were being seen attempting to mimic a Pahkwa-Thanh but only ended up mimicking portions of the crewman’s body.

They attempt to mimic the appearance of a person, right down to their clothing; however, they don’t seem to be able to mimic details such as facial features, instead appearing as faceless beings, quickly earning the name the “Faceless Intruders” during an incursion of the USS Gorkon.

They are solanogen-based lifeforms, which can only exist in a subspace environment. Their bodies emanate tetryon particles as a byproduct of their metabolism, similar to thermal emissions in normal humanoids. Preliminary analysis suggests their cognitive processes are based on tetryons rather than electrons, giving them the potential to have superluminal cognitive functions. This may also lend to their telepathic abilities, able to maintain connection across vast distances.
