In Rick and Morty, few concepts are as important—or as deliberately confusing—as the Central Finite Curve. For years, the series presented its multiverse as effectively limitless. There were infinite Ricks, infinite Mortys, infinite Earths, and seemingly infinite possibilities.

Then Evil Morty revealed the catch: the Ricks we had been watching were living inside a carefully selected portion of infinity.

And Evil Morty wanted out.

So how do you bring down the Central Finite Curve? The Season 5 finale, “Rickmurai Jack,” gives us the answer. It requires understanding what the Curve really is, obtaining knowledge possessed by Rick C-137, taking control of the Citadel, and generating enough power to punch through the barrier separating Rick’s curated multiverse from everything beyond it.

First, Understand What the Central Finite Curve Is

The Central Finite Curve is not simply another universe or physical wall floating somewhere in space. It is a partition of the multiverse.

According to Evil Morty, the Ricks effectively separated the universes in which Rick Sanchez is the smartest being alive from universes where he is not. Inside the Curve, Rick almost always occupies the top of the intellectual hierarchy. Outside it lies the rest of infinity: realities where someone—or something—can surpass him.

That changes the meaning of Rick’s supposedly limitless adventures. He has access to infinity, but it is an infinity with boundaries.

A useful analogy is the infinite set of numbers between 1 and 2. There are endlessly many numbers within that interval, but none of them is 3. The Central Finite Curve operates on a similar idea: an enormous, potentially infinite collection of realities constrained by a particular condition.

Evil Morty’s goal is therefore not to destroy the multiverse. He wants to escape the section of it dominated by Ricks.

Step One: Get the Knowledge Inside Rick C-137’s Brain

Knowing that the Curve exists isn’t enough. You need to know how it was constructed and how its underlying dimensional technology works.

That is where Rick C-137 becomes essential.

Evil Morty already possessed part of a scan of Rick’s brain from the events surrounding “Close Rick-counters of the Rick Kind.” When Rick arrives at the Citadel in “Rickmurai Jack,” Evil Morty secretly completes the scan during their dinner.

Rick refuses to explain how to bring down the Curve voluntarily. Evil Morty doesn’t need him to.

He simply takes the information.

The scan gives Evil Morty access to knowledge connected to the Citadel and its dimensional drive, the machinery he needs to penetrate the Curve.

This is arguably the most important part of his entire plan. Evil Morty doesn’t defeat Rick by becoming a better version of Rick. He defeats the system by extracting the one piece of information Rick has spent years accumulating: how the system works.

Step Two: Take Control of the Citadel

Evil Morty’s presidency is much more than a political victory.

It gives him control of the largest concentration of Rick-built interdimensional infrastructure in the Curve.

The Citadel contains enormous amounts of technology, portal infrastructure, dimensional machinery, and thousands of Ricks and Mortys. By becoming its president, Evil Morty puts himself in position to turn the institution created by Ricks into the machine that will free him from them.

This also explains why his plan develops over several seasons. Bringing down the Curve is not something that can be accomplished with an ordinary portal gun. Evil Morty needs resources on a civilization-scale level.

The Citadel provides them.

Step Three: Sabotage the Portal Network

When Evil Morty begins his escape, he compromises the Citadel’s portal system.

Ricks attempting to flee discover that their portals no longer lead where they expect. Meanwhile, Rick and Morty discover that the Citadel’s supply of usable portal fluid has effectively been compromised as well.

This serves two purposes.

First, it prevents the population of the Citadel from easily escaping or interfering with Evil Morty’s plan.

Second, the destruction and chaos become part of the process powering what comes next.

Evil Morty is not merely escaping the Citadel. He is dismantling the entire Rick-controlled infrastructure surrounding him on his way out.

Step Four: Feed the Dimensional Drive

The most horrifying part of the plan involves the Citadel’s resurrection technology.

The Phoenix Protocol had previously allowed versions of Rick to transfer into replacement bodies after dying. Evil Morty redirects this system. Instead of safely resurrecting its users, the process feeds bodies into machinery connected with his escape operation. The result supplies the dimensional drive with the enormous resources necessary for the breach.

This detail matters because it demonstrates the extraordinary scale of the operation.

Breaking through the Central Finite Curve apparently requires far more than entering coordinates into a portal gun. Evil Morty needs the Citadel’s dimensional technology operating at catastrophic intensity.

He essentially converts the heart of Rick civilization into a giant multiversal battering ram.

Step Five: Punch a Hole Through the Curve

With Rick’s knowledge, control of the Citadel, and the dimensional drive operating, Evil Morty finally activates the system.

A massive rupture opens.

The Citadel begins collapsing as Rick and Morty desperately attempt to escape, while Evil Morty launches his small spacecraft directly toward the breach.

Then he crosses the boundary.

For the first time, a major character deliberately leaves the collection of universes defined by the Central Finite Curve.

The Curve’s familiar visual representation subsequently breaks apart before Evil Morty.

He has done what generations of Ricks built their civilization to prevent: he has reached the wider multiverse.

Step Six: Build a Portal System That Works Beyond Rick’s Multiverse

Once outside, Evil Morty produces one of the most important objects in the episode: a portal gun whose portals are gold rather than Rick’s familiar green.

He fires it, walks through, and disappears.

The symbolism is hard to miss.

Green portals belong to the technological ecosystem associated with Rick and the Central Finite Curve. Evil Morty’s gold portal visually signals that he has entered—and learned to navigate—a different multiversal system.

His objective was never simply to kill Rick.

It was to reach a place where Rick no longer defines the rules.

So, Did Evil Morty Actually Destroy the Central Finite Curve?

This is where the phrase “bring down” deserves some nuance.

The Season 5 finale clearly shows Evil Morty breaching and escaping the Curve, while its representation appears to fragment. Later episodes continue exploring the consequences of that event, so describing the Curve as simply erased from existence can be an oversimplification. The safer interpretation is that Evil Morty successfully compromised the barrier that isolated Rick’s controlled portion of the multiverse and created a path beyond it.

That distinction makes his accomplishment more interesting.

Evil Morty did not need to conquer infinity.

He only needed to break the wall around his part of it.

The Real Meaning of Bringing Down the Curve

The mechanics of Evil Morty’s plan are entertaining science-fiction technobabble, but the Central Finite Curve also works as an idea.

Rick presents himself as someone who refuses limitations. He mocks governments, religion, institutions, authority, morality, and virtually every system that claims to impose rules on him.

Yet the Curve reveals that Ricks created perhaps the biggest limitation imaginable.

They reorganized their experience of infinity so that they would remain exceptional.

Evil Morty recognizes the contradiction. Instead of trying to become the smartest person inside Rick’s system, he rejects the system itself.

That is why bringing down the Central Finite Curve requires more than machinery. Evil Morty first has to recognize that what looks like infinity is actually a cage.

Then he steals its architect’s knowledge, captures its infrastructure, turns its power against itself, and punches a doorway through the wall.

In Rick and Morty, that is how you bring down the Central Finite Curve.

You stop trying to beat Rick at his own game—and leave the game entirely.
