    Roger Stern writes; John Buscema pencils.

Creation Story

Nebula is Roger Stern and John Buscema’s Copper Age Avengers addition. The Avengers #257 (July 1985) introduces her as a space pirate claiming to be Thanos’s granddaughter (Thanos was presumed dead at the time of her introduction, having died in the Bronze Age Starlin cosmic run). Stern writes; Buscema pencils. The issue is both her first appearance and first cover.

The character’s relationship to Thanos has been retconned multiple times across decades of stories. Her original 1985 claim was that she’s Thanos’s granddaughter; subsequent runs walked the relationship back to “adopted granddaughter of Kronos” (Thanos’s grandfather); modern continuity (post-2008 cosmic-Marvel) treats her as Thanos’s adopted daughter and Gamora’s adopted sister. The MCU adaptation uses the adopted-daughter framework consistently.

The cyborg framework is a defining character note. Thanos progressively replaced Nebula’s body parts with cybernetics as punishment for her failures during her training and his service. The framework was developed across the original Stern and Starlin runs and has been preserved across virtually every subsequent Nebula portrayal, including the MCU films where Karen Gillan’s Nebula has progressively more cybernetic replacements across each appearance.

The Infinity Gauntlet

The Infinity Gauntlet #1 (July 1991) by Jim Starlin and George Perez featured Nebula in a substantial role across the crossover, including the climactic moment where she briefly seizes the Gauntlet from Thanos. The arc is widely regarded as one of the strongest extended cosmic-Marvel storylines and gave Nebula her most prominent pre-MCU character work.

The Infinity Gauntlet sequence (Nebula trapped in a partially-decayed body, freed by Thanos’s defeat, briefly cosmic-omnipotent) is one of the most-cited sequences in the broader Infinity-saga storytelling.

The MCU era

Karen Gillan’s Nebula debuted in Guardians of the Galaxy (2014, James Gunn) as a secondary antagonist. Subsequent films progressively developed her character arc:

The MCU’s Nebula has one of the most-developed character arcs in the broader Marvel Cinematic Universe. Gillan’s performance is widely regarded as one of the strongest sustained character developments in modern superhero film. The MCU’s extensive screen time accelerated collector demand for first-print The Avengers #257 across multiple price-spike cycles.

Frequently asked questions

The questions readers and collectors ask most.

What is Nebula's first appearance?

Nebula's first appearance is The Avengers #257 (July 1985), created by Roger Stern (writer) and John Buscema (artist). The issue is both her first appearance and first cover. Nebula debuts as a space pirate claiming to be Thanos's granddaughter.

Is The Avengers #257 valuable?

Yes. The Avengers #257 is a Copper Age Marvel key with strong adaptation-driven collector demand. High-grade copies (CGC 9.8) have crossed $400 at auction. Newsstand variants carry a meaningful premium. The book's value spiked sharply after Karen Gillan's casting as Nebula in Guardians of the Galaxy (2014) and has held.

Is Nebula really Thanos's granddaughter?

It depends on continuity. Her original 1985 claim was that she's the granddaughter of Thanos; the precise relationship has been retconned multiple times. Modern continuity (post-2008 cosmic-Marvel) treats her as Thanos's adopted daughter and Gamora's adopted sister, with no actual biological relationship to Thanos's family. The MCU adaptation uses the adopted-daughter framework. The 1985 'granddaughter' framing is sometimes treated as Nebula's deliberate misrepresentation rather than canonical fact.

Why is Nebula a cyborg?

Thanos progressively replaced her body parts with cybernetics as punishment for her failures during her training and his service. The cyborg framework was developed across the original 1985 to 1991 Stern and Starlin runs. The MCU adaptation preserves the framework: Karen Gillan's Nebula has progressively more cybernetic replacements across the films, with the abuse-by-Thanos framework as the explanation. The cyborg-from-Thanos-abuse register is one of the canonical character markers.

How did Karen Gillan's Nebula develop across the MCU?

Substantially. The 2014 Guardians of the Galaxy positioned Nebula as a secondary antagonist; subsequent films progressively developed her character arc through Guardians Vol. 2 (2017), Avengers: Infinity War (2018), Avengers: Endgame (2019), and Guardians Vol. 3 (2023). The MCU's Nebula has one of the most-developed character arcs in the franchise: from antagonistic adopted daughter to reluctant ally to full Guardians member to the team's emotional anchor by Vol. 3. Gillan's performance is widely regarded as one of the strongest sustained character developments in modern superhero film.
