Introduced as an Avengers villain, Nebula was a space pirate later revealed to be the granddaughter of Thanos, the Mad Titan. That was generally the extent of her characterization for a while, occasionally popping up as a minor antagonist in the cosmic side of the Marvel Universe.
She received major emphasis, however, during the original Infinity Gauntlet storyline in 1991. Nebula had a major role in helping the heroes take down Thanos, briefly even wielding the Gauntlet for herself. Following her arrest on (and escape from) Titan, Nebula was turned into the cyborg that she later become infamous for.
Outside of minor role in the 2006 Annihilation event, Nebula mostly remained in the background figure in the cosmic Marvel Universe in the following year, but her appearances in the Marvel Cinematic Universe (as portrayed by Karen Gillan) have seen a renewed interest in the character that's spread back into the comics, with her first solo series hitting in February 2020.

Nebula provides examples of:
- A God Am I: When she wields the Infinity Gauntlet, intending to use it for selfish (and vindictive) reasons.
- Amazing Technicolor Population: Has blue skin, a trait among her race of people.
- Archnemesis Dad: Or rather, Granddad in the comics, regarding her antagonistic relationship with Thanos.
- Bald Women / Bald of Evil: Originally wearing long hair in her earliest appearances, Nebula has since become known for her bald head in her most contemporary portrayals. In the MCU, baldness among Luphomoids is considered canon, which isn't the case for them in the mainstream Marvel universe.
- Cybernetics Eat Your Soul: Inverted by her comic book counterpart, who was already morally dubious when she got her cybernetic enhancements.
- Cyborg: She becomes this at some point after The Infinity Gauntlet.
- Dark Action Girl: As a female, cybernetic space pirate.
- Green-Skinned Space Babe: Defied. Unlike Gamora, who's typically shown as tough and sexy, Nebula isn't typically treated the same way. That's not to say she isn't attractive to some people, but Nebula's most recent interpretations emphasize her deadliness over looks.
- Evil Is Hammy: This panel from The Infinity Gauntlet pretty much sums it up.
- Mysterious Past: Unlike her cinematic counterpart, much of Nebula's backstory in the comics is unknown. Her relationship with Thanos in particular has never really been explored to the extent it has in the MCU.
- Space Pirate: How she was introduced. She even seized control of Thanos' Sanctuary II ship at one point.
- Supervillain: How she's usually portrayed in the comics.
