Invincible Season 4: The Definitive Ranking of All 8 Episodes

Invincible Season 4 is in the books, and yeah, it was another big swing for Prime Video. The show kept its wild streak alive with a 100% critics score on Rotten Tomatoes. Not every episode lands equally, but the season builds into a genuinely gnarly run of payoffs and 'oh, we’re really doing this' moments the show has been teasing for years. One chapter, though, faceplants hard enough to set a series low on IMDb. Overall? The late-game action and character work more than make up for it.

Fair warning: spoilers for Invincible Season 4, Episodes 1-8 ahead.

Season 4, ranked from best to least-best

1. "Don’t Do Anything Rash" (Episode 7)

   This is the season’s big swing and the payoff the whole run builds toward. Mark, Nolan, and Thaedus take the fight to the Viltrumites, and it escalates into a full-on planetary-level move: they blow up Viltrum. Thragg responds by showing exactly why he’s the scariest thing in this universe, killing Thaedus, almost killing Nolan, and sparing Mark in a way that somehow makes everything worse. It’s tense start to finish, looks insane, and leaves an even bigger nightmare on the board: surviving Viltrumites heading to Earth to regroup and repopulate. Peak Invincible.

2. "Give Us a Moment" (Episode 5)

   The first head-on clash between the Coalition’s lineup and the Viltrumites hits hard. Body count-wise, it’s lighter than Episode 6, but the dread is thicker here. The Viltrumites smother the team, Conquest is pure menace, and both Mark and Oliver look one bad second away from disaster. Mark’s final exchange with Conquest is stomach-turning. Between the brawl and an emotional one-two with Debbie and Nolan’s heated reunion (and Nolan trying to be a father to two sons who have every reason to hate him), this one balances gore and heart like a pro.

3. "I’ll Give You the Grand Tour" (Episode 2)

   Unlike most of the early-season table-setting, this one is locked into the Viltrum arc. We get a bleak history lesson about the plague that wiped out a huge chunk of the Viltrumites, and Nolan teams up with Allen to hunt down weapons that can actually hurt them. It quietly kickstarts Nolan’s redemption track, too. The action is solid, but the gut-punch worldbuilding and odd-couple bonding between Nolan and Allen are what stick.

4. "You Look Horrible" (Episode 6)

   Fallout hour. After the first Viltrumite collision, Mark is barely hanging on, separated from the rest of the crew with Nolan and Oliver. That isolation gives Nolan and Oliver space for some surprisingly warm, messy character beats while Mark recovers. Elsewhere, Allen and Tech Jacket start a fun, unlikely friendship. The closing fight isn’t the season’s sharpest, but it sets the stage perfectly for Episode 7’s detonation.

5. "Don’t Leave Me Hanging Here" (Episode 8)

   A quieter finale than you might expect after that warpath in Episode 7, but it knows what it’s doing. Mark’s PTSD is front and center, Eve’s abortion is handled head-on, and Nolan’s attempt at redemption inches forward without the show pretending he deserves forgiveness yet. Two end beats lock in the momentum for Season 5: Mark’s unnerving talk with Grand Regent Thragg, and Allen stumbling into a discovery that immediately blows up in his face.

6. "I Gotta Get Some Air" (Episode 3)

   Very much in the premiere’s lane: side villains, side missions, and Mark fraying around the edges. It edges out Episode 1 thanks to livelier action and stronger character work for Eve and Oliver. It also leaves a few hooks dangling for later seasons — most notably Robot and Monster Girl getting trapped in the Flaxan dimension. There’s promise here, just not the same juice as the Viltrumite material.

7. "Making the World a Better Place" (Episode 1)

   Solid reentry into the chaos after last season’s Conquest showdown. We check in on folks still reeling — Cecil, Eve — and get a sharper, more ruthless Mark than we’ve seen. The minor villains add some color without sticking in your brain. The best bit is Conquest’s escape at the end; it tees up the larger conflict the back half pays off in spades. Good, not great.

8. "Hurm" (Episode 4)

   The outlier, and not in a good way. This detour lands as the series’ lowest-rated episode on IMDb, and you can see why: it feels disconnected from the main throughline at the exact moment the Viltrumite war is about to ignite. There’s some sharp humor and useful growth for Mark, but the characters he meets in hell don’t make much of an impression. Maybe Season 5 retroactively makes this chapter matter. For now, it’s a speed bump.

Season 4’s biggest strength is how the back half cashes in on conflicts that have been simmering for years — once the show locks onto the Viltrumites, it’s relentless. What was your favorite episode? Sound off; I’m curious where you land, especially on that finale’s softer tone after such a brutal build.
