Rom #1 (1979)
The males or Sciwraiths as they came to be known were highly advanced, creating the Drakillar battle fleet capable of warp drive and used against the Galadorian inhabitants of the “Golden Galaxy.” The Wraiths were also skilled in a form of bioengineering that crossed both sorcery and sciences, which they used to create the Hellhounds out of predators from various worlds. Female Wraiths generally rely on sorcery.
The Dire Wraiths are metamorphs, able to trans form into virtually any shape. While they inherited this ability form their Skrull forebears, the Dark Nebula’s magical energies greatly enhanced it, allowing them to alter their mass to some extent (unlike their Skrull relatives); however, most Wraiths lost their shape-shifting ability when Wraithworld was neutralized.
