Thanos Fact — October 20, 2026

Today's Fact

Verified against five independent sources. Issue cited below.

Thanos was originally a skinny Metron rip-off, not Darkseid!

The Featured Fact

Jim Starlin conceived Thanos in college psychology classes, and when editor Roy Thomas offered him an issue of Iron Man, the Mad Titan was born in Iron Man #55 (February 1973) — plotted and drawn by Starlin, script by Mike Friedrich. But Starlin has admitted Thanos wasn't originally a Darkseid knockoff at all: "In my first Thanos drawings, if he looked like anybody, it was Metron" — the skinny, amoral knowledge-seeker of Jack Kirby's Fourth World. Thomas looked at the Metron-like figure in his floating chair and said: "Beef him up! If you're going to steal one of the New Gods, at least rip off Darkseid, the really good one!"

The Metron DNA survived the bulk-up. Thanos kept the floating chair — his Space Thrones are the lingering nod to Metron's Mobius Chair — and Metron's detached, beyond-good-and-evil amorality was recast as Thanos's full-blown nihilism: a character who "didn't believe in anything beyond the unknowable allure of death." Even in his 1973 debut, Thanos shows up thinner than the modern bruiser, already carrying Darkseid-inspired touches like the boots.

Forty years later, the ghost of the skinny design walked back on panel. Infinity (2013) introduced Thane — Thanos's secret son, revealed in New Avengers #10 (2013) by Jonathan Hickman & Jim Cheung — a tall, gaunt, purple Eternal who looks strikingly like what Starlin first drew. One comics writer has even suggested Thane may carry the original Metron connection. Starlin himself once said he "liked beefing him up so much that he continued to grow in size" — and Thanos has been growing ever since.

Why It's Obscure

Everybody "knows" Thanos is a Darkseid copy — the knock-off reputation followed him all the way to the MCU. The real origin story, told by Starlin himself in a 1998 interview with Jon B. Cooke for Comic Book Artist #2, is backwards: Thanos started as a Metron knockoff and was only redesigned to look like Darkseid on editorial orders.

1970

Darkseid debuts — Superman's Pal, Jimmy Olsen #134. Jack Kirby's Fourth World gives comics Darkseid, Metron, Orion, and the Mobius Chair. Three years later, Marvel's newest cosmic villain quietly shops in Kirby's wardrobe.

1972

The college origin — Between U.S. military service and comics work, Starlin takes a psychology class and dreams up Thanos and Drax the Destroyer: "I'm not sure how he fit into it, just anger management probably."

1973

Iron Man #55 — Thanos debuts in "Beware the Blood Brothers!" — the same issue also introduces Mentor, Drax, Starfox, and Kronos. Thanos himself isn't even on the cover; the Blood Brothers are.

The chair

Metron's Mobius Chair → Thanos's Space Thrones. The skinny seeker of knowledge glides through the multiverse gathering information; the beefed-up nihilist keeps the throne and swaps knowledge for death. Same chair, different hobby.

Trivia

Jack Kirby never drew Thanos. For all the Fourth World DNA baked into the Mad Titan — the design, the chair, the "New Gods" swagger — the King himself never put pencil to the character in a comic. Thanos lived almost entirely inside Starlin's own books for years.
