Share
Everything about Argo City, the Kryptonian city that survived the destruction of Krypton and where Kara Zor-El, aka Supergirl, comes from. In this article: its origin, its miraculous post-explosion survival, the progressive kryptonite poisoning, Kara's rescue, how it differs from Kandor (the city preserved by Brainiac), and its film and television adaptations. By the end, you'll understand precisely how this surviving fragment of Krypton made Supergirl's arrival on Earth possible.

The origin of Argo City on Krypton
Argo City was one of the planet's great cities Krypton before its destruction. According to DC canon, it was a major scientific city, home to several great Kryptonian families - notably that of Zor-El and Alura In-Ze, Kara's parents.
Characteristics before the destruction:
- Population: several hundred thousand Kryptonians
- Advanced scientific research center
- Emblematic crystalline architecture
- Home of the family of Zor-El (Jor-El's kin)
- A community relatively isolated from the rest of Krypton
This family importance explains why Argo City plays a major narrative role in the surviving Kryptonian mythology. It is where Supergirl comes from, whose story our complete analysis of Kara Zor-El develops.
The miraculous post-explosion survival
The most extraordinary aspect of Argo City is its miraculous survival of Krypton's destruction. When the planet explodes, a substantial fragment breaks away and keeps its physical integrity thanks to several converging factors:
- Favorable position during the explosion (fragment ejected rather than destroyed)
- Active Kryptonian energy shield around the city
- Artificial atmosphere preserved by Kryptonian technology
- Local gravitational force maintained
- Survivors: the Zor-El family and several other Kryptonians
This miraculous survival makes Argo City the largest fragment of Krypton to survive intact after the explosion (apart from Kandor, preserved by Brainiac before the destruction). It is a Kryptonian mini-world in cosmic exile.
Life in space, in cosmic exile
For several Earth years after the destruction of Krypton, the inhabitants of Argo City live in exile in space. This period is one of the most poetic in the Kryptonian mythology:
- Kryptonian civilization maintained in the city-fragment
- Culture, language, traditions preserved
- Population reproducing normally (including Kara as a child)
- Occasional exchanges with other galactic civilizations
- Hope of finding a new habitable planet
This period of exile lasts roughly 10-15 Earth years depending on the canonical versions. It is during this period that Kara Zor-El is born, grows up and receives her complete Kryptonian education - which is why she remembers Krypton (unlike Kal-El, who was a baby when he arrived).
The progressive kryptonite poisoning
The tragedy of Argo City is its progressive kryptonite poisoning. The ground supporting the city slowly turns into green kryptonite, condemning all its inhabitants to a slow death:
- The crystalline ground begins to emit kryptonite radiation
- The inhabitants gradually develop symptoms
- Kryptonians are fatally vulnerable to kryptonite
- The situation becomes irreversible despite scientific research
- All the inhabitants will die if nothing is done
Faced with this situation, Zor-El and Alura make the same decision Jor-El and Lara made before them: send their daughter Kara to Earth in a space capsule. This decision creates a tragic parallel between the two generations of the House of El.
The rescue of Kara Zor-El
The young Kara Zor-El is saved by her parents, who place her in a space capsule bound for Earth, where her cousin Kal-El (Superman) had already arrived several years earlier.
Essential differences from Kal-El's arrival:
- Kara arrives as a teenager (vs. a baby for Kal-El)
- She has conscious memories of Krypton and Argo City
- She already speaks Kryptonian fluently
- She carries an acute grief for everything she has lost
- She has to adapt to a foreign culture at the difficult age of adolescence
This age difference is central to understanding Supergirl's psychology. To explore her differences from Superman in detail, our analysis of the differences between Kara Zor-El and Kal-El expands on the context.
Difference from the Bottle City of Kandor
Argo City and Kandor are the two great surviving Kryptonian fragments. But their differences are essential:
- Kandor : captured BEFORE the destruction by Brainiac, preserved at microscopic size
- Argo City : survives AFTER the destruction as a fragment, at normal size
- Kandor : kept intact in a bottle
- Argo City : progressively exposed to kryptonite
- Kandor : all inhabitants alive (microscopic but healthy)
- Argo City : all inhabitants dead from poisoning (except Kara)
- Kandor : potential for restoration (New Krypton arc)
- Argo City : permanently destroyed, no inhabitants left
This duality (Kandor preserved, Argo City destroyed) is a rich narrative device. DC canon thus offers two parallel scenarios of Kryptonian survival, each with its own tragedies.
Film and television adaptations
Argo City has seen several on-screen adaptations:
Supergirl 1984 (film). The film starring Helen Slater opens by presenting a surviving Argo City before telling the story of Kara's journey to Earth. This adaptation remains one of the most faithful to the comics canon.
Smallville. The CW television series briefly develops the concept of Argo City when Kara is introduced (season 7), played by Laura Vandervoort.
Supergirl on The CW (2015-2021). The series starring Melissa Benoist devotes several episodes to Kara's origin in Argo City. Her mother Alura appears in several flashbacks and hologram scenes.
Supergirl: Woman of Tomorrow (2026). The DCU film starring Milly Alcock could potentially include Argo City as part of Kara's origin story.
Symbolism of the surviving fragment
Beyond its narrative role, Argo City carries a strong symbolic charge:
The illusion of survival. Argo City seems to survive the destruction of Krypton, but it is only a temporary reprieve. Kryptonite progressively condemns the survivors. This dimension is a meditation on the impossibility of truly escaping loss.
The generational parallel. Zor-El and Alura literally repeat the decision of Jor-El and Lara: sending their only child to Earth in a space capsule. This repetition creates a poignant generational cycle.
The preservation of childhood. Unlike Kal-El, who has no memory of Krypton, Kara grows up in Argo City and keeps intact memories of her native civilization. This psychological dimension radically distinguishes the two Kryptonian cousins.

FAQ — Frequently asked questions
What is Argo City?
Argo City is one of the great cities of Krypton that survived the planet's destruction. It is where Kara Zor-El (Supergirl), daughter of Zor-El and Alura, comes from. The city lived in exile in space for 10-15 years before being destroyed by kryptonite poisoning.
How did Argo City survive the destruction of Krypton?
A substantial fragment of the planet broke away during the explosion while keeping its physical integrity. Several converging factors: a favorable position, an active Kryptonian energy shield, an artificial atmosphere preserved by Kryptonian technology, and a maintained local gravitational force.
What is the difference between Argo City and the Bottle City of Kandor?
Kandor was captured BEFORE the destruction by Brainiac, preserved at microscopic size in a bottle. Argo City survived AFTER the destruction as an ejected fragment, at normal size in exile in space. Kandor is intact with living inhabitants; Argo City was destroyed by kryptonite poisoning with all its inhabitants dead (except Kara).
Why was Argo City destroyed?
Through progressive kryptonite poisoning. The crystalline ground supporting the city slowly turned into green kryptonite, emitting radiation that is deadly to Kryptonians. The inhabitants gradually developed symptoms and all died after several years.
Why does Kara Zor-El remember Krypton but Superman doesn't?
Because Kara was born and grew up in a surviving Argo City after the destruction of Krypton. She lived her childhood and adolescence in a preserved Kryptonian fragment, which gave her conscious memories. Kal-El, on the other hand, arrived on Earth as a baby, straight from Krypton before the destruction.
Does Argo City still exist?
No, in the main canon. Argo City was destroyed by kryptonite poisoning and all its inhabitants died (except Kara, who was sent to Earth). Unlike Kandor, which could be restored (New Krypton arc), Argo City is lost forever.
Conclusion
Argo City is one of the most poignant pieces of lore in the entire Kryptonian mythology. A miraculous surviving city condemned by kryptonite poisoning, Supergirl's original home, a generational parallel to the sending of Kal-El: it embodies the tragic dimension of the Kryptonian diaspora.
