Rick Sanchez from Rick and Morty isn't just the smartest man in the multiverse: he's also the most dangerous. In his hands, everything is a weapon, and seemingly innocuous inventions often pose a terrible threat to those around him. Sometimes these inventions jeopardize Morty, other times his family, earth, or the entire multiverse.

Rick's inventions in Rick and Morty are often as absurd as they are dangerous, pushing his scientific mind to its limits for no other reason than to prove that he can. Some have demonstrated their lethality by racking up a staggering body count, while the lethal potential to others is latent, ticking away like a bomb just out of sight.

10 Heistotron

Heistotron wasn't designed as a weapon, but like most Rick inventions, that doesn't mean he isn't one. Rick doesn't respect heists, which is probably why the robot he builds to pull off the perfect heist instead goes on a planet-destroying rampage.

Heistotron also makes "One Flew Over the Crewcoo's Morty" an excellent parody episode, as the robot attacks the narrative structure of Rick's plan just like it attacks planetary cores. Though vulnerable to the same pitfalls of circular logic that flummox many sci-fi robots, Heistotron is an incredible threat while active, the mechanical embodiment of Rick's cynicism.

9 Time Stopper

Only Rick would think it's acceptable to threaten time itself in the name of avoiding an unwanted conversation with family. The time stopper in "Ricksy Business" isn't a weapon, but by enabling Rick, Summer, and Morty to act without repercussion, it makes all manner of lethal scenarios possible. Worse, even after the device is deactivated, it turns basic human indecision into a reality-multiplying rip in the space-time continuum.

Given the extreme lethal potential of this invention, it's no surprise that an entire organization of temporal police forces exists to prevent just such abuses of the timeline. Of course, since Rick doesn't respect that organization or any other, the threat of time-stopper technology continues to loom.

8 Time-Save Device

The time-save device in "The Vat of Acid Episode" effectively grants Morty invincibility by allowing him to revert to a "save point" whenever he dies (or simply regrets a decision). The true danger, however, lies in how this change affects Morty mentally. Free of any repercussions for his actions, Morty acts out every violent, infantile impulse.

In doing so he leaves a trail of bodies across a multitude of universes, and it is only the terrible understanding of what he has done that finally stops him. The time-save device would be dangerous in anyone's hands, but in Morty's it is catastrophic. In a heartbreaking moment, the reckless decision-making which the device inspires in Morty even destroys the relationship he most cherishes.

7 Decoy Families

Originally invented as a defense mechanism against the many enemies Rick has made throughout the cosmos, the decoy families in "Mortyplicity" prove lethal in their own right. All of the decoys, equally convinced that they are the originals, prove willing to hunt down and murder one another to save themselves.

Just like the real Rick and many of those he considers friends, none of the clones care about collateral damage, dogfighting and streetfighting with other clones without any concern about who else might be hurt. Assuming the clone family has even a fraction of the intelligence, sociopathy, or impulsiveness of the originals, the clone families pose a threat not only to one another but also to anyone caught in their path.

6 Doolittle Machine

Sometimes Rick's decisions force the family to abandon earth altogether or face destruction. The Doolittle Machine in "Morty's Mind Blowers" brings about just such an event. By granting Morty the ability to understand animals, the Doolittle Machine drags the unwitting teenager into a planet-wide conspiracy of squirrels.

Once the squirrels realize that a human is on to their Illuminati-like string-pulling, they immediately move to put down Morty and anyone with whom he might have shared the secret truth. Rick considers the threat posed by the squirrels so great that it is easier to relocate to another dimension altogether rather than face them. In this way, the Doolittle Machine qualifies as a planet-wiping device, as it begins a chain of events so dangerous that even the mighty Rick finds it easier to run.

5 Love Potion and Antidote

Morty's hormonal teenage impulsiveness and Rick's scientific showboating combine with deadly force in "Rick Potion #9" when Morty asks his grandfather to create a potion to make Jessica fall in love with him.

Thanks to some well-placed sneezes, the infectious love of Morty spreads, and the antidote Rick brews in an attempt to treat the problem only makes things worse, ruining earth by turning every human into monsters befitting a Cronenberg horror film. In one of the series's finest episodes, either unable or unwilling to do the necessary work to fix the problem, Rick abandons that version of earth to its fate, leaving the planet's inhabitants to kill or survive as they will.

4 Space Cruiser

Rick and Morty season 5

Rick's space cruiser, featured in "The Ricks Must Be Crazy" and other episodes, possesses a variety of lethal gadgets. These include comparatively pedestrian weapons like a laser capable of surgically crippling opponents, as well as a device that creates a biological replica of an enemy's dead loved one only to dissolve the replica in front of the enemy's eyes as a form of psychological warfare.

Most dangerous of all is the ship's AI, which considers towing a sun around as bait so it can kill an alien god a good way to blow off steam. Last, the AI has such a phenomenal understanding of multiverse politics that within minutes it arranges a peace treaty between humans and giant spiders on an alternate earth, suggesting that it could just as easily start wars if it wanted to.

3 Neutrino Bomb

While many of Rick's most lethal inventions were never meant to be dangerous, the neutrino bomb from "Pilot" and other episodes absolutely was. The neutrino bomb is a species killer, capable of massive, instantaneous destruction of life, and as with most things Rick, this feature is only part of the bad news.

Rick has a terrible habit of forgetting about the neutrino bombs that he builds and deploys when drunk, leaving Morty to deal with the aftermath, in effect placing the fate of entire worlds in the sweaty hands of an accident-prone teenager. Jerry might be naive, but Rick could learn a thing or two from him when it comes to not causing extinction events.

2 Microverse Battery

The space cruiser's AI and armaments pale in lethal potential compared to what lurks under its hood. As seen in "The Ricks Must Be Crazy," the microverse battery powers Rick's car through the slave labor of an entire alien race created and held captive within. The Inception-like layering of universes inside the microverse battery only multiplies its destructive potential. Rick can, at a whim, destroy the multiple pocket dimensions within, erasing them along with everyone who has ever lived inside.

Rick isn't exactly at his most insightful when trying to justify the battery's existence to Morty, but he obviously doesn't much care as long as his car runs. The microverse battery shows Rick at his most megalomaniacal and godlike, proving how little he values the lives of others, and demonstrating what awesome power he has to wipe them out if so inclined.

1 Portal Gun

Rick's portal gun, featured in numerous episodes, is the most dangerous weapon in his arsenal, for it is the portal gun that extends his reign of disaffected chaos across the entire multiverse. Thanks to the portal gun, there is no limit to the cosmic reach of Rick Sanchez.

When Rick arms a notorious assassin, crashes an intergalactic economy by changing a one to a zero or just makes a sneaky joke to oblivious aliens, it is only because the portal gun puts him in the position to do so. Every earth that Rick Cronenbergs, loses to a global squirrel cabal, abandons to an alien invasion or otherwise dooms only suffers its fate because of the portal gun. The portal gun symbolizes everything that Rick is: infinite possibility and utter damnation.
