In The 100, there's a contingent of people inside Mount Weather who oppose the use of Outsiders as Human Resources and help the captured Ark kids fight back against the Mountain's security personnel.
24: Somewhat obvious in Season 7. The rogue CTU consisting of Chloe, Tony, and Bill have all had their looks changed to fits this trope and make them look tougher. Chloe has had her hair dyed dark, but the most noticeable change is former Bureaucrat Bill Buchanan wearing black head to toe with a two day stubble. He's one beret short of a parody. Tony's transformation is more convincing.
The French Resistance from 'Allo 'Allo! (two of them, reflecting the political divisions in the group). They're virtually all female and the Communist leader wants to sleep with Rene.
Parodied when Harper makes contact with a resistance group on Earth, fighting the oppressive tyrants, led by his cousin. He almost leaves in disgust when he finds out it's just small band of misfits instead of a planetwide network.
Of course, his cousin's message at the end of the episode (even though he himself is killed) results in multiple uprisings on Nietzschean-held worlds.
Babylon 5: When EarthGov starts becoming more and more corrupt under President Clark, the crew of the titular station declares itself independent from the Earth Alliance until such time as Clark is removed from power. They also start broadcasting their own news program called "Voice of the Resistance" informing people of the true state of their government, while the government-controlled ISN does the opposite. Eventually, with the help of other races, they are able to remove Clark's military strength, allowing politicians to try to remove him from power. He ends up blowing his brains out but not before setting Earth's Kill Sats to fire down. Luckily, the satellites are destroyed before that happens.
Funnily enough at least one of the leaders of the first was a leader in the second.
Even funnier that the main leaders of the New Caprican Resistance, including the one who led the old Caprican Resistance were not only what they were waging war against, they were the one who are responsible for the damn things!. No wonder Tigh was so upset.
Subverted Trope in the two-parter "Rise of the Cybermen/The Age of Steel", where the badass leader of La Résistance against the Mad Scientist John Lumic is London's most wanted...for parking tickets. "I was fighting the system! Park anywhere!" he says. No wonder they accepted Mickey as a replacement so easily.
Played straight in season 3 with The Year That Never Was, although it was only mentioned briefly by Martha as she faces the Master.
La Resistance is formed in the pilot, whose main purpose is to find out the Taelons' purpose on Earth. In later seasons, several world governments, under pressure from the Taelons, declare martial law and start hunting down the resistance members. Both Boone (season 1) and Kincaid (seasons 2-4) are protectors of a Taelon called Da'an, although both are also secretly members of La Résistance. Initially, the resistance is well-funded, as it was founded by a wealthy tycoon. Their numbers are also high. Later on, though, the numbers and the funds dwindle. By the end, there are very few members left. In the final season, there are less than a dozen members left, as they fight to prevent the Atavus takeover (in this case, it's more about the world not knowing or not believing about the Atavus, although a good number of officials are human/Atavus hybrids).
It also doesn't help that one of their own gives up many names and locations under duress, resulting in multiple cells being eliminated. Once the world governments start cracking down on suspected Resistance sites in order to please their Taelon Companions, the numbers start going down.
This is the entire premise of Falling Skies. And it's not only the humans-some of the Skitters are resisting as well.
Firefly: The crew of Serenity turn into this during the movie.
First Wave starts with only one person resisting the secret alien takeover, joined by another person shortly after. However, they constantly publish about their exploits on an online journal, which, as they find out, a good number of people start reading. A biker gang finds out about the existence of aliens and starts hunting them down indiscriminately, which forces Cade to take them down instead. Later on, an alien reveals that not all of them agree that an invasion of Earth is a good idea and is willing to subvert his people's efforts. The last few seasons reveal the existence of Raven Nation, an organization that goes more in line with this trope.
Fringe: The protagonists are part of this in the final season, against The Observers. They're actually called The Resistance.
In Volume Four of Heroes, Micah organizes a resistance against the government roundup efforts under the name "Rebel". It isn't quite La Résistance yet, but it's getting there. He currently has Claire, Hiro, and Ando working for him.
Merlin: This applies, surprisingly well, to the main villains of the series.
Mr Lucky: The pilot episode involves the title character losing his casino, his savings and very nearly his life because his partner is discovered to be a member of the local resistance movement.
The 2014 Mini SeriesRésistance is a fictional drama about the French Resistance based on real events.
Revolution: Episode 3 has Team Matheson trying to help out this one group of rebels. In episode 5, Ken 'Hutch' Hutchinson is a member of one group...in fact the only one left of that group by the time he appears. Episode 9 has Team Matheson getting help from one rebel group to infiltrate Philadelphia where Monroe and Danny are. Episode 11 has the rebels being attacked by Monroe's helicopters and they are forced to gather up in one location. Episode 12 has Miles Matheson recruiting Jim Hudson to the rebel cause. Episode 13 has the rebels lead an attack and discover that Monroe has acquired a small nuclear bomb. Episode 14 has the rebels and the Georgia Federation form a coalition against the Monroe Republic. Episode 15 has the coalition go to Jasper to help out Miles. Episode 17 has the coalition lose 270 men and gets reduced to 30 men in one drone strike. Episode 18 has Rebel Leader Wayne Ramsay killed off. The first season finale has the rebel Nora Clayton killed off.
Secret Army accurately portrays the Belgian Resistance as a series of different organizations, all more or less working towards the same goal. Lifeline is an apolitical escape line, funneling resistors and downed Allied airmen out of occupied Europe. They sometimes find themselves at odds with those organizations that undertake violent resistance, and come under scrutiny by their British handlers who fear that Lifeline, like many other resistance groups, is a Communist cell.
Sliders: Nine out of ten episodes had the gang sliding into a world that had serious societal problems, running afoul of the authorities that benefit from them, and joining the local resistance to set things right. Sometimes they would be the ones to start the resistance.
Stargate SG-1: Several thousand years ago, a group of Go'auld decided to put down the Villain Ball and reject the Large Ham, Body Snatching ways of their race and its leader Ra and actually, *gasp* co-exist peacefully with voluntary hosts. They formed a resistance known as the Tok'Ra, literally meaning, "Against Ra". They join up with two other resistance movments, a network of Jaffa slaves secretly working to overthrow the Go'auld, and Stargate Command, which can be considered the primary Tau'ri resistance. These then form an Alliance, which defeats the Go'auld once and for all (with help from allies like the Asgard; of course, it's the Replicators who actually end up killing the last Goa'uld off).
A small-scale example among the Ori, after Vala ends up somehow transported to the Ori galaxy. It turns out that Seevis, who shows himself as one of the most pious men in the village, is actually leading a small group opposed to the Ori. They plan to sabotage the new Ori ships that are being built on the planet. However, their efforts are thwarted and Tomin, Vala's husband, kills all of them but Vala.
A variant occurs in the episode Shadow Play, where La Resistance is planning to seize power to prevent a World War. The Resistance exists only in one man's radiation-damaged mind.
The Maquis mostly fights the Cardassians, but isn't averse to some precision strikes against the Federation, largely because they blame Federation peace treaties for letting the Cardassians run roughshod over any number of planets...plus, the Federation considers them terrorists. They occasionally get decent characterization:
Michael Eddington: Why is the Federation so obsessed with the Maquis? We've never harmed you. And yet we're constantly arrested and charged with terrorism. Starships chase us through the Badlands and our supporters are harassed and ridiculed. Why? Because we've left the Federation, and that's the one thing you can't accept. Nobody leaves paradise. Everyone should want to be in the Federation. Hell, you even want the Cardassians to join. You're only sending them replicators because one day they can take their "rightful place" on the Federation Council. You know, in some ways you're even worse than the Borg. At least they tell you about their plans for assimilation. You're more insidious. You assimilate people and they don't even know it.
In one Voyager two-parter, most of the crew becomes part of the actual French Resistance via the holodeck.
The Bajoran Resistance. While the Bajorans are shown as sympathetic, and the Cardassians as almost pure evil, the Resistance itself is definitely shown as The Revolution Will Not Be Civilised, and Deep Space Nine shows many former Resistance members having trouble adapting to the fact that the Occupation is over, and they don't need to fight anymore. Plus, some just see The Federation as the new oppressors.
Cardassia initially has the Dissident Movement which has been working underground for years against the Central Command. Occasionally, Deep Space Nine finds itself dragged into this particular political issue whenever Dissident fugitives end up on Deep Space Nine fleeing from Cardassia. Later on, when the Cardassians are under the control of the Dominion, a full blown resistence movement starts. Since the Federation desperately needs the movement to succeed (since the Federation/Dominion war isn't going well for the Federation), it sends in a Bajoran resistence veteran to teach the Cardassians how to do it. The irony of this situation is not lost on either Bajorans or the Cardassians... or even the Federation, for that matter.
Also during the Dominion War arc, several of the main and recurring characters form a Resistance group to stop the Dominion from destroying the minefield that keeps ships from passing through the wormhole. They fail, but they do manage to disable the station long enough to keep it from blowing up the Defiant.
In V (1983): The Miniseries, alien fascists invade and humanity fights back...those who don't collaborate or do nothing, anyway.
In V (2009), a small resistance group is eliminated in the pilot, leaving only four: one of the original members of the group, a V hiding on Earth, an FBI agent, and a Catholic priest (ex-army). The group later grows slightly to include a gun-for-hire and the chief medical officer aboard Anna's ship (a member of the Fifth Column secretly opposing Anna's leadership). Later, they even manage to recruit Anna's daughter Lisa. The Grand Finale shows that a much larger resistance group called Project Ares has been set up by high-ranking military and government leaders shortly after the arrival of the Vs. Needless to say, they are well-funded and even have a base in a bunker located a mile beneath Manhattan.
