Dire Wraith

Hailing from a dark nebula, the evil Dire Wraiths seek to conquer all they see. The only force able to oppose them is Rom and the Solstar Order. The Solstar Order prevailed, causing the Wraiths to scatter throughout the galaxy. The Dire Wraiths secretly invaded the Earth long ago.
The Dire Wraiths wield powerful dark magic and are able to assume any form they wish. They are also able to gain new abilities by using the blood of other life forms.
Fiction
IDW Generation 1 continuity
While discussing Optimus Prime's recent annexing of Earth, Miles Mayhem mentioned that Action Man could be of help to a "situation" in Northern California, referring to where hidden Dire Wraiths were being hunted by Rom. Secret Raiders Rom gave a vague explanation to the Cybertronians of who the Wraiths were and why he was on Earth. The Divine Source of Liberty Once he'd made peace with Optimus Prime, he further elaborated on the Wraiths' interest in Ore-13 and how it made them harder to detect. O Ship of State
The Dire Wraiths eventually managed to take over the EDC's Bikini Atoll base. G.I. Joe was sent to defeat them and recapture the facility. The Modern World While this happened, Marissa Faireborn was meeting with the President and given the case of Ore-13 that the Wraith Colton was carrying around before Rom killed him. This was the cue for the Wraiths in the White House to try and reclaim the case. Armed with a firearm that fired armor piercing bullets, Marissa made short (if bloody) work of the Wraiths in the vicinity before she called in Thundercracker as backup. The Wraiths managed to take control of the Seeker clones before Thundercracker and D.0.C. destroyed them. Buster proved able to sniff out the Wraiths from the humans while Bob simply mutilated one before eating it. The leader of the Wraith cell barricaded herself in the situation room. This proved ineffective against Thundercracker who casually destroyed the wall and all her minions. At wit's end, she merged magic and Ore-13 growing to Cybertronian size. Adopting the form of a Wraith Hawk, she engaged Thundercracker in the air and managed to rip off his cannon arm. Thundercracker shouted a warning that the arm was full of ammunition and that she ought to be careful with her fire hands. Her wings were incinerated and she impaled on the Washington Monument. Marissa meanwhile mowed down the rest of the Wraiths with a standard rifle. Thundercracker & Buster Save the World
Notes
- While it was believed that Marvel Comics owned the Dire Wraiths (using them as recently as 2011), that is not the case, as they were mentioned in Rom's original toy commercial. However, while Marvel doesn't own the name or concept of the Dire Wraiths, they do own their design for the Wraiths, forcing IDW Publishing to give the Wraiths a new look.
