When humans finally conquer space, we'll still want to keep other creatures as pets. Some science-fiction pets are among our favorite characters, but others, you just want to flush out the airlock. Here's our list of the best and worst.
Spot, Data's Orange Tabby Cat from Star Trek: The Next Generation
Who: Data's number 1 friend that didn't wear a Devo-esque visor on his face.
Why he's awesome: He's probably one of the only cats in the universe that has an infinitely advanced AI at his beck and call.
Bonus points: Anything that pisses Riker off is a big plus in my book.
Willis the Bouncer from Robert Heinlein's Red Planet
Who: A sound mimicking furry ball that every kid should have as a friend.
Why he's awesome: In a 1960's era future, when a dog just won't cut it, the only way to really impress the kids at school is with an alien that doubles as a soccer ball. And here's a clip from the Fox miniseries adaptation.
R2D2, Star Wars
Who: The yin to C3PO's (annoying) yang that brings logic and light to any situation through a series of flickering lights and bleeps.
Why he's awesome: He's a moving trashcan that manages to be more likeable than most of the Star Wars palz extended cast.
Porthos, Captain Archer's Beagle from Enterprise
Who: Easily one of the more tolerable characters on Enterprise. Mostly because he didn't talk.
Why he's awesome: He's a beagle! How can beagles not be cute? Also, I feel like after the unfortunate Scotty related transporter incident, he deserves a nice memorial.
Ampersand, Y the Last man
Who: The world's ending, every man is dead, you're an aspiring escape artist pining away for your lost girlfriend and you're all alone. What do you do? Have crazy monkey antics with your favorite jungle friend with a punctuation mark as a name.
Why he's awesome: Not to spoil too much, but he may or may not be humanity's key to getting the XY's back in action.
Who: Marvel's own alien bulldog and member of the non-human branch of the Avengers.
Why he's awesome: He's super strong, can eat anything and once latched onto the Thing.
Dog the Robot from Half Life 2
Who: Alyx Vance's No.1 go to robotic buddy who helps when your path is blocked by other dimensional beings or just wants to play fetch with your grav gun.
Why he's awesome: He's a giant robot with the personality of a dog. Do you need more?
Pen Pen, from Neon Genesis Evangelion
Who: A genetically altered super smart penguin that lives with Misato Katsuragi during the Angel apocalypse.
Why he's awesome: While the series has moments of intense despair and darkness, you can always count on jerky, anime humor involving naked people and penguins to brighten your day.
K-9 from Doctor Who
Who: Dr Who's multi-generational robotic canine companion.
Why he's awesome: He's gotten a series of spinoff stories and was even parodied on South Park.
Nibbler from Futurama
Who: Nibbler is part of an ancient race of Nibblonians who protect the universe from giant glowing brains that make everyone stupid. Er, Stupid-er.
Why he's awesome: He can eat about 1,000 times his body mass to, uh, produce dark matter.
Gaspode, from Terry Prachett's Discworld series
Who: A talking dog with human intelligence that attempts to bring "Hollywood" to Discworld.
Why he's awesome: He's an endless source of snarky remarks and regularly uses his speech to manipulate humans when he needs food.
Who: A puff ball with a body that guaranteed to produce family friendly fun times.
Why he's awesome: CJ-7 can help you repair torn relationships with certain parental figures and bring people back from the dead.
Einstein, Doc Brown's dog from Back to the Future
Who: You might be under the impression that a certain Family Ties alum might be the Doc's best time traveling friend in this series, but you'd be wrong. This adorable little terrier follows Doc whenever her goes.
Why he's awesome: As long as you ignore the craptacular animated television series, Einstein is always cute, helpful and never obnoxious.
Ein, Cowboy Bebop
Who: A super brained corgie that gets stranded on the Bebop.
Why he's awesome: Although they never really get into it in the series, Ein is a "data dog" that possesses super intelligence that allows him to answer phones and steer cars.
Bubastis, Ozymandias' lynx from Watchmen
Who: When you're a super genius David Bowie impersonator with the world at your fingertips what do you do next? You create a genetically engineered psychedelic colored lynx as a companion.
Why he's awesome: He takes one for the team for the sake of furthering an evil plan for his master.
Who: The main furry faced protagonist of the Gremlins series.
Why he's awesome: While I'm pretty much a fan of all the gremlins, I can't deny the greatness that is Gizmo channeling his inner Rambo.
Seymour from Futurama
Who: Seymour is a part of one of the most tear jerking episodes of Futurama involving Fry recounting the story of the most loyal dog that ever lived.
Why he's awesome: Did you see the last scene? He's the most loyal dog that ever lived! Also, we can rest easy knowing that alternate timeline Fry gave Seymour a great life.
Bronx from Gargoyles
Who: Bronx is the dog version of the Manhattan gargoyle clan. During the whole series you only see one other gargoyle beast, but unlike Budeka, Bronx gets a whole episode devoted to him befriending an Amish kid.
Why he's awesome: Gargoyles are already pretty high on the cool supercreatures scale, but add a dog personality to the mix, and you've got gold.
Roach from WALL-E
Who: They weren't lying when they said that after the world ended there would be nothing left but cockroaches. Fortunately, the end of the world also gave them charming personalities!
Why he's awesome: Making me want a roach as a pet is an epic win in my book.
Kevin and Dug from Up
Who: Kevin is a rare, brilliantly colored giant bird that Carl and Russell accidentally find in Paradise Falls. Dug is sweet golden retriever with a collar that allows him to talk.
Why they're awesome: It takes a lot to make slapstick giant birds funny, but Pixar does a magnificent job. And Dug? He's exactly what I imagine an actual talking dog to sound like. SQUIRREL!
Tribbles from Star Trek
Who: Fuzzy, purring little meat pets that take over the original Enterprise.
Why they suck: Pets rocks were bad enough, why would they think that a massively multiplying furry pet rock would be better?
Who: Alien puppet that takes over a really lame sitcom in the 80's. If ever you want to torture someone without the use of waterboarding, show them and episode of ALF… or Small Wonder.
Why he sucks: Look me straight in the eye and tell me you didn't scream in horror when you saw that clip.
Who: A fat alien cat that ends every sentence with an annoying "snarf!" sound.
Why he sucks: Is he a lizard or a cat? I'm going to go with meth induced demonic lovechild.
Teddy from A.I.
Who: An animatronic intelligent Teddy Rucksbin from the future that accompanies David in a search for the Blue Fairy.
Why he sucks: Ok, now I understand that some people might take issue with Teddy's position on the worst list but he's a toy that's alive. That's pretty much the worst nightmare of most 8-year-old kids. And me.
Slimer from Ghostbusters
Who: A green ghost that terrorizes the Ghostbusters team by covering everything in slime.
Why he sucks: For those of us born in the mid 80's and watched the Ghostbusters cartoon first, we expected to see cool ghost antics when we finally saw the movie. Instead, we were greeted with a grotesque blob that was pretty evil.
Div-x from Penny Arcade
Who: You might remember the Sony Dix-X player, an ahead of its time technical marvel.
Why he sucks: According to Penny Arcade Comics, he's a foul-mouthed drunk that's teetering on the edge of killing us all.
Pets from Children of Men
Who: When the world's gone infertile, people turn to animals to provide comfort in the end of humanity.
Why they suck: I have nothing against the animals in Children of Men, personally, but seeing all the dogs, cats and birds cluttering people's homes can be an ominous image.
Selacious Crumb from Star Wars
Who: He's a little fox-lizard thing that hangs out with Jabba the Hut and laughs at all his lame jokes.
Why he sucks: Everybody hates the skinny jerk in the corner with the stupid laugh.
Gleek from Superfriends
Who: The alien monkey pet of the Wondertwins.
Why he sucks: Usually if he was featured in Superfriends, you could count on him popping out to end the episode on a lame joke.
Independence Day Dog from Independence Day
Who: If you're like me then you probably laughed at the idea of a ball of flame chasing a golden retriever down a tunnel.
Why he sucks: Was it really necessary to have a slow motion explosion behind a dog? And wouldn't all that heat ultimately cook them all in that storage locker?
Then Again:...he's immune to explosions. And that's pretty cool. Dodging fire like that, he's like a canine Neo. Maybe he should have been best?
Why they suck: I'll just point you in the direction of this.
