Invincible's biggest
key issues, ranked.

Robert Kirkman, Cory Walker and Ryan Ottley spent 144 issues (plus a #0) building one of the most quietly ambitious superhero comics of the last twenty years. It starts as a coming-of-age story about a teenager who can suddenly fly, and by the end it's rewritten what half its cast is capable of, killed off characters readers genuinely didn't expect to lose, and turned a handful of one-panel cameos into some of the show's biggest villains.

Here's the run, ranked not by resale value but by what actually happened on the page. If a moment reshaped the series or introduced someone who mattered later, it's here.

Invincible #1: the origin, obviously

Everything starts here. Mark Grayson's first flight, the first appearance of Omni-Man, Deborah Grayson, and Titan, and the quiet cameo of a girl in a school corridor who'll turn out to be Atom Eve. It reads like a fairly straightforward teen-superhero opener on a first pass, which is exactly what makes issue three such a gut-punch when you already know what's coming.

Invincible #7: the Guardians of the Globe wipeout

This universe's answer to the Justice League gets introduced and slaughtered in the same issue. Immortal, Darkwing, Martian Man, Red Rush, Aquarus, Green Ghost and War Woman are all dead by the last page, and the reveal of who did it, and why, is the moment Invincible stopped being a coming-of-age book and became something considerably darker.

Invincible #11: the Viltrum reveal

Omni-Man finally tells Mark where they actually come from. It's framed as a bedtime origin story at the time, and it isn't until issue 102, told from the other side by Grand Regent Thragg, that you realise how much of what you were told here wasn't the full picture.

Invincible #16: Angstrom Levy's first appearance

One panel, barely a footnote at the time. Levy becomes one of the series' most important recurring villains, and one of the very few Invincible characters confirmed early on for the Amazon show's future seasons. First appearances rarely announce themselves this quietly.

Invincible #19: Battle Beast enters

Battle Beast shows up here for the first time, alongside Magnattack, Magmaniac and Tether Tyrant. He becomes one of the most enduring threats in the book, gets a cover appearance of his own eleven years later, and eventually a daughter who inherits his mantle.

Invincible #60: the first death that actually hurt

Rex-Splode dies here, in a company-wide crossover issue with a quadruple gatefold cover. Compared to what comes later this feels almost restrained, but it's the point where the series proves its deaths are going to stick.

Invincible #100: the milestone

A hundred issues in, and the retailer order numbers on this one dwarf everything around it. Milestone issues don't always deliver a plot payoff to match the number on the cover, but this one's a genuine turning point for the scale the series was willing to operate at.

Invincible #108: Angstrom Levy's death

The villain introduced in a single panel back in issue 16 finally dies here, a full decade into the character's run. Long game storytelling, and proof Kirkman was planting seeds far earlier than anyone gave him credit for at the time.

Invincible #111: the one that changes everything

Cecil Stedman, the man who's been quietly running the whole board since issue one, has his head crushed by Robot. Atom Eve loses a leg in the same issue. If you only read one issue of Invincible outside the opener, most long-time readers will point you here.

Invincible #120: Battle Beast falls

Grand Regent Thragg kills Battle Beast, closing out one of the series' longest-running threats and making it brutally clear just how far above everyone else the Viltrumite hierarchy actually sits.

Invincible #132: Oliver and Onaan

Mark's half-brother Oliver dies here, alongside Onaan, one of Thragg's own children. Family has always been the emotional core of this book, and losing Oliver specifically is one of the harder deaths to see coming.

Invincible #140 & #141: Thragg and Omni-Man

Back to back, Grand Regent Thragg finally dies, and Omni-Man follows him in the very next issue, heart complications from the fight that killed his own greatest enemy. Two of the series' biggest figures gone within thirty days of each other, and the story never quite feels the same after.

Invincible #144: the torch gets passed

Emperor Argall is introduced and killed in the same issue, Markus Murphy takes up the Invincible name, and Battle Beast's daughter and Angstrom Levy's son both get their first appearances. A genuine changing-of-the-guard issue, and one that quietly sets up most of what the series does with its next generation of characters.

The honest takeaway

What strikes me looking at this list end to end is how few of Invincible's biggest moments were flagged as big at the time. Angstrom Levy's first appearance is a single unremarkable panel. Cecil Stedman spends a hundred issues in the background before the one that matters. That's the difference between a comic engineered to feel important and one that actually earns it over time, and it's a big part of why Invincible back issues have stayed collectible well past the usual first-arc hype window most new series get.
