Top 10 Cartoon Aliens in Movies and TV

These characters are out of this world. Welcome to, and today we’re counting down our picks for the top 10 cartoon aliens in movies and TV.

For this list, we’re focusing on unique cartoon alien designs in the vein of traditional animation. We’re excluding popular comic book superheroes that look like the rest of us humans, such as Superman and Starfire.

#10: Kif Kroker
“Futurama” (1999-2003; 2008-13)

It’s the 31st century, and Kif is a bashful alien from the planet Amphibios 9. On the Nimbus starship, he’s also the 4th Lieutenant of the Democratic Order of Planets as well as Captain Zapp Brannigan’s assistant. While his nervous nature and lack of self-confidence is characterized as so pathetic that it’s amusing, his affections for his girlfriend Amy sustain him and his fans. Their relationship has helped keep Kif in the hearts of television audiences throughout “Futurama”’s run.

#9: Zim
“Invader Zim” (2001-02; 2006)

For this little green guy, the world is not enough. He’s a villainous antihero and an ambitious one, because his main goal is to conquer planet Earth with extreme prejudice. Overzealous as he may be, you’ve got to admire his determination and the go-getter attitude that comes with his confidence – especially since his plans always fail. But at least his cover seems to be working; despite the color of his skin and the fact that he won’t eat people food, few seem to realize he isn’t actually human. Zim’s also got a trusty sidekick named GIR, who is a scrap metal robot that assists him on his adventures.

#8: Martian Manhunter
“Justice League” (2001-04) / “Justice League Unlimited” (2004-06)

Also known as J’onn J’onzz, he’s the sole survivor of a Mars invasion. He’s also a telepathic shape-shifter with superhuman strength, flight and an ability to phase-shift until he’s intangible. When not learning about humanity via his detective disguise as Officer John Jones, he’s using his abilities and superior Martian intellect to help the Justice League heroes fight their battles on earth.

#7: Stitch
“Lilo & Stitch” (2002)

Stitch could easily be mistaken for a weird-looking koala or a dog, but it? He? isn’t either of those things. This strange blue creature is not only an alien, but also a unique and illegal genetic experiment by one. He’s designed to be rambunctious, aggressive and destructive by nature, so his new friend Lilo might be the only one that can tame him. An unlikeable outcast to everyone else, it’s thanks to the sweet young Lilo that we see the beauty of Stitch’s innocence and how he’s just really misunderstood.

#6: Roger
“American Dad!” (2005-)

He’s lived on Earth since the ‘40s and has been alive for centuries. Roger hides from the CIA with the Smith family by living in their suburban home, which they offered to him as repayment for rescuing Stan from Area 51. Initially shy and naïve, Roger soon became crass and outspoken, and is now more known for callously and selfishly scheming his way in and out of sticky situations. He’s a depraved little rascal and an alcoholic, but still a very sociable alien and a master of disguise.

#5: Kang & Kodos
“The Simpsons” (1989-)

Kang and Kodos are a pair of siblings from the planet Rigel VII, and are famous for their recurring plots to conquer and enslave Earth, specifically in “The Simpsons”’s “Treehouse of Horror” Halloween specials. These deep-voiced, drooling, one-eyed aliens seem to spend more time laughing at our misfortunes rather than being successful invaders, though. While their cameos are brief, their sardonic commentary is always a good look at humanity from the outside in.

#4: Nerdlucks / Monstars
“Space Jam” (1996)

In “Space Jam,” Mr. Swackhammer and his criminal alien minions the Nerdlucks kidnap and enslave the Looney Tunes gang to use them as outer space amusement park attractions. The Tunes strike a deal for their freedom by suggesting they play a fate-determining game of basketball. However, when the scheming Nerdlucks steal the skills of real-life NBA players, all bets are off. Goodbye Nerdlucks and enter the big, hulking, scary-looking Monstars. The transformed aliens prove that appearances can be quite deceiving when they break out their basketball moves.

#3: Dr. John A. Zoidberg
“Futurama” (1999-2003; 2008-13)

This crustacean creature comes from the planet Decapod 10 and moved to Earth to practice medicine… poorly. No one in the Planet Express delivery crew where he works particularly likes him, but that doesn’t stop him from being lovable - even if he’s sad and lonely about being ostracized. If anyone respects him, it’s definitely TV audiences, because even though he’s homeless, seems to know nothing about human anatomy and is a failed comedian, he’s still hilarious.

#2: Krang
“Teenage Mutant Ninja Turtles” (1987-96)

About as dangerous as he is gross, Krang’s form is just the talking, disembodied brain of a banished warlord from Dimension X. On Earth, he allies himself with Shredder, and is carried around in a mechanical body so he can stay mobile in his Technodrome fortress, of which he is commander. Krang is an intelligent, vindictive and ruthless being when it comes to his enemies, especially the Teenage Mutant Ninja Turtles.

Before we identify our top alien pick, here are some honorable mentions.
- The Great Gazoo
“The Flintstones” (1960-66)
- The Chicken from Outer Space
“Courage the Cowardly Dog” (1999-2002)
- Lord Nibbler
“Futurama” (1999-2003; 2008-13)
- Aliens (Various)
“South Park” (1997-)

#1: Marvin the Martian
“Looney Tunes” franchise (1948-)

Marvin the Martian is one of Bugs Bunny’s long-time foes, and he’s an evil, soft-spoken ray-gun wielding alien that’s out for Earth’s destruction. He’s always dressed with Roman fashion sense and basketball shoes, and is sometimes accompanied by his Martian dog K-9. This guy’s meek, casual, and articulate way of plotting and executing his threatening ideas is what makes him a very unique extra-terrestrial. Just because he’s quiet doesn’t mean he isn’t dangerous… but he’s also funny and entertaining – just like the rest of those Looney Tunes characters – and that’s why he’s number one!
