"Shroomie" shuttle 

A small shuttlecraft was used by two members of this species to board Enterprise. ()

"Shroomie" starship 

In September 2151, this vessel of an unknown species destroyed the subspace relays Echo One and Echo Two. It also attacked the United Earth vessel  twice. The third time it attempted to do so, Enterprise was ready for it and, using their newly installed phase cannons, damaged the alien vessel to such an extent that it fled the scene at high impulse. It was never seen again.

As a 22nd century starship, this vessel was highly advanced in a technological regard, possessing strong shields and technology that prevented invasive scans from other vessels. It utilized a powerful energy weapon that fired green, crescent-shaped pulses. It had a crew of at least fifteen individuals, and carried at least one shuttlecraft. It also had the ability to emit a powerful dampening field, which could effectively disable an  starship. ()

Tret's containment vessel

Triglobulin harvester's starship 

This unidentified hostile alien vessel possessed high-yield particle weapons, heavy deflector shielding, a tractor beam and a grappling/drill used for piercing starship hulls.

In 2151, a vessel of this class attacked and killed the crew of an Axanar cargo ship, and later hooked the crew up to a bio pump which was used to extract triglobulin from their blood.

Several days later, the hostile vessel returned and attacked , which had discovered the Axanar vessel and had sent a distress call from the ship.

During the encounter, the hostile vessel was more than a match against the Earth ship's spatial torpedoes. The hostile vessel quickly disabled Enterprises warp drive and captured the small Earth ship in its tractor beam. The hostile ship proceeded to conduct a sub-molecular bioscan of the ship's crew, before locking onto the ship and beginning to drill into Enterprises hull.

Before too much damage was done, Enterprise was rescued by an Axanar warship that first disabled the hostile alien's tractor beam, releasing Enterprise, before successfully destroying the ship in a one-sided fire fight. ()

The ship's captain requested permission to return to the surface after several of its compartments had flooded with radiation, causing injuries to several of the passengers and crew, including the Antaran Hudak. The ship's request was denied; subsequently, assistance was rendered to the vessel by Enterprise. ()
