While the other members of the serial were forgotten, in the 1940's, the creators tried to cash in on the newly released Wonder Woman and brought Honor back in a limited run comic book. In this incarnation, she was injured when her space rocket exploded, and was repaired by dark-matter aliens. (Not that the writers has any idea what dark matter was.) The mixture of dark and light matter in her replacement heart generated powerful gravity and density fluctuations. She became a strong flying brick, able to manipulate her own gravity as well as make herself as dense and invulnerable as diamond. (The writers didn't really understand density either.)
In the 1972, Cygnus X-1 was found to be a black hole. Because of the renewed interest, Honor's superhero identity was renamed Cygnus. There was a relaunch of the title, featuring Honor as a more 'realistic' astronaut who was doing a deep exploration beyond the solar system when her space-ship was sabotaged. (Again, the writers had no idea about actual astronomical distances. This ended up a little more like Lost in Space...) The aliens were still dark-matter aliens, only the quantum heart they used to repair Honor's injuries fused into a tiny black hole in her chest. (No idea how her blood kept circulating.)
- Density Control: Cygnus can be as solid as almost any material, allowing her to punch with the force of a comet, hold her ground like an alien obelisk, and shrug off nearly any attack. Conversely, she can decrease her density to reduce her weight, or become intangible.
- Gravity Control: Due to the link between mass and gravity, Cygnus can fly. She has also used her enhanced density to make herself the center of gravity. This was mostly used during her space missions to pull objects to her.
- Space Adaptation: It is unclear if this is a separate power, but Cygnus does not need to breathe and is unaffected by vacuum or high pressure. in the 30's, the serial didn't include this, because, ya-know, space has normal air.
- Massive Hand-to-Hand combat power. Cygnus is a flying brick on par with the most powerful super-beings in the galaxy. Several times, she has been stated to be the most powerful in this comic universe.
