Thanos First Appearance: Origin Comic and Key Issue

Before becoming the most lucrative big bad in cinema history withAvengers: Infinity WaretEndgame,Thanoswas born in the pages of an issue of Iron Man — drawn by a young Jim Starlin just out of the army. Iron Man #55 also marks the first appearance of Drax the Destroyer and Mentor, laying the foundations for Marvel's entire cosmic universe.

For collectors, Iron Man #55 has become one of the most explosive Bronze Age keys on the market. Its value increased tenfold between 2015 and 2020, driven by the MCU wave. It's an issue that combines mythological importance (the introduction of Marvel's ultimate villain) and relative rarity in high grades — a combination that supports high prices.

Publication context

Jim Starlin, just hired by Marvel in 1972, created Thanos in a college psychology class. Inspired by the gods of Jack Kirby's New Gods (notably Darkseid) and by the Freudian concept of Thanatos (death drive), he draws a cosmic titan obsessed with death itself. Mike Friedrich, Iron Man's official screenwriter, co-signed the script but Starlin is the real narrative architect. The issue was published without fanfare — no one at Marvel anticipated the character's future importance.

The Story Inside

The plot sees Iron Man and Drax (introduced as a man resurrected by Mentor to destroy Thanos) team up against the Mad Titan in an unusual cosmic tale for the Iron Man series. Thanos appears first in shadow, then on full page in a memorable splash — seated on a throne, dominant, menacing. Starlin immediately injects the ambition and grandeur that will characterize all future appearances of the character.

The cover

Jim Starlin signs a dynamic cover showing Thanos in full battle against Iron Man and Drax, against a starry space background. The Titan is already in its final form: striated chin, golden armor, imposing stature. The text “Beware the Blood Brothers!” » is misleading — it is Thanos and Drax who are the real stakes of the issue. The composition, although typical of the Bronze Age, has gained retroactive iconic status.

Edition and variants

The circulation of Iron Man #55 is estimated at between 150,000 and 200,000 copies. There is no variant cover per se, but the copies withMark Jewelers insertare significantly rarer and command a premium of 40-60%. The pence price version (UK distribution) is also sought after by British collectors.

CGC census data

The CGC census lists around 4,500 graded examples. The scarcity in high grade is severe: less than 20 copies in 9.8 and around 80 in 9.6. The vast majority are concentrated between 4.0 and 7.5, typical of the Bronze Age keys that circulated in drugstore spinner racks. Each sale of a 9.8 is an event followed by the entire market.

Value by grade

Price history

Iron Man #55 was a $500 issue in 9.4 prior to 2012. Thanos' first appearance in the filmThe Avengers(post-credits scene) triggered the rise. Each subsequent film amplified the trend: a 9.8 went from $10,000 in 2014 to $50,000 in 2018 (Infinity War's release), then peaked at over $120,000 in 2021. The post-bubble correction brings prices back into the $75,000–100,000 range — still ten times above levels pre-MCU.

Points of vigilance when purchasing

The major problem with Iron Man #55: theMarvel Value Stamp(inside page) — definitely check that it is intact. THEspine rollsetstress linesare common on this issue whose paper is particularly fine. Pay attention to the restoration on the corners and the edge – pre-CGC examples have often been “improved” by dealers. Professional pressing is acceptable but restoration (color touch, piece fill) devalues ​​considerably. Require a CGC slab with universal label (blue).
