Fans of the iconic science-fiction apocalypse show The 100 are preparing to say goodbye this year as the show makes its final rotation around the Earth. After six seasons featuring countless main character deaths and new character additions, three apocalypses, and four entirely new groups of people, it's been a long road - though we're excited about the prequel.
What better way is there to prepare for the final season than rewatching the six seasons that made this show what it is today? Since season seven premieres in April, and you might be tight on time, we've rounded up the ten best episodes according to IMDB for your bingeing pleasure.
Season 2 - "Blood Must Have Blood Part 1" - 8.9
This episode features high levels of drama and tension. It opens with Bellamy and Maya sneaking through Mount Weather, rescuing Echo and the Grounder army from Mount Weather's cages, and then proceeding to infiltrate the fortress to take down the acid fog defenses for Clarke and Lexa. Meanwhile, Clarke and Lexa ready their armies for battle with epic speeches and battle plans.
Underneath the mountain, Octavia shows off how far she's come as a fighter with Indra and the rest of her battalion. Infamously, this episode also features Lexa's great betrayal, a moment that will haunt Lexa and Clarke's relationship for many years to come.
Season 1 - "We Are Grounders Part 2" -9
After season one's sandstorm of threats, the of the 100 finally learn to survive in this season finale - hence the perfectly fitting title, "We Are Grounders." In the first season, they faced food scarcity, medical nightmares like plagues and poisons, and rough terrain, but this episode features the 100 surviving against their toughest enemy yet: a fully-formed and trained army of Grounder warriors bent on wiping them out.
They're outnumbered and outmatched, still recovering from a plague that weakened many of them and even killed a few. Bellamy, Finn, Clarke, Raven, and Monty take the lead in this episode as they formulate the perfect plan to save the 100 from nearly unbeatable odds.
Season 6 - "The Gospel of Josephine" - 9
This episode focuses on the arrival of Josephine Lightbourne, a character whose arrival was foreshadowed heavily throughout the first four episodes of season six. Fans likely did not expect Josephine to arrive in Clarke's body; as a result, watching Eliza Taylor play someone other than Clarke is both dazzling and nervewracking.
Josephine turns out to be a worthy nemesis to Clarke, and she spends her first episode fooling all our favorite Earth people into thinking she's Clarke, manipulating them all the while for her gain. Meanwhile, Earthkru manages to uncover the secret of the Primes, and sadly so too does Bellamy uncover the secret of Clarke's bodysnatcher.
Season 5 - "Damocles Part 1" - 9
In Part One of the Season Five finale, Octavia leads Wonkru into war against the Elegius prisoners and it doesn't go so well. Wonkru is decimated thanks to leaks from Marcus Kane that McCreary finds in Diyoza's journal. Frightened and broken, they flee the battle, leaving Bellamy, Octavia, Indra, and Gaia stranded in the trenches, the latter of whom is mortally wounded.
Meanwhile, Spacekru tries to fix the problems that Blodreina, Clarke, Diyoza, and McCreary created by retrieving Madi so that she can take her place as commander and reform Wonkru to lead them back into battle.
Season 6 - "Adjustment Protocol" - 9
In the penultimate episode of season six, tensions have never been higher as the Earth people try to rescue as many innocent lives as possible from the tyranny of the Primes, all the while trying their best to not do any extra harm to anyone at all, which follows this season's theme of "doing better."
Clarke infiltrates the Primes posing as Josephine. While Bellamy, Octavia, and Gabriel wait on the outskirts of Sanctum for Clarke to lower the radiation shield, Abby, Raven, and Jackson use the Primes' computer lab to save Madi under the guise of making Russell enough Nightblood serum to resurrect his family.
Season 5 - "Sleeping Giants" - 9.1
This episode opens masterfully with a scene that directly mirrors one we've seen in season one. This time, instead of Grounders stringing Jasper up injured in the middle of a clearing as a threat, we see Clarke stringing up an Eligius prisoner in an elaborate trap set for Diyoza's crew.
Clarke eventually is captured after stowing Madi away in a safe hiding place. Meanwhile, Spacekru adventures onto the mostly empty Eligius spacecraft, where they overhear Diyoza's crew pursuing someone on the ground. Bellamy leads all of Spacekru, save Murphy and Raven, to the ground to rescue who he thought was Octavia, only to discover once he arrives that Clarke had survived Praimfaya.
Season 4 - "Die All, Die Merrily" - 9.2
Having teased the fated, epic Conclave traditions for four seasons, The 100 finally gave us a taste of the ultimate Grounder competition in season four, episode ten.
Octavia receives help from unexpected places as she fights to the death, representing Skaikru in the Conclave meant to save one clan from Praimfaya. Meanwhile, after Bellamy spots Echo interfering illegally in the conclave, he races to stop Echo before she can take out Octavia. The episode ends in a twist after it's revealed that Clarke (who has been suspiciously missing from the episode after a dispute with King Roan) betrayed Octavia and took the bunker for Skaikru in a desperate attempt to save the human race from Luna's nihilism.
Season 4 - "Praimfaya" - 9.3
"Praimfaya" follows a core crew of fan-favorite characters as they try to escape the end of the world by pulling off one of the most desperate and far-fetched plans they've ever come up with. This episode highlights how far the characters have come in of hard skills and leadership qualities as the team splits into smaller units to tackle the tasks that must be completed before their departure to space.
The episode opens with a heartbreaking speech from Octavia in which she its she's not ready to lead Wonkru, a dark foreshadowing to the events of season six. It ends, tragically, with Spacekru having to leave Clarke behind on Earth, not knowing that her Nightblood enabled her to survive the violent radiation of Praimfaya.
Season 2 - "Blood Must Have Blood Part 2" - 9.3
The season two finale opens with a ruthless act from Jaha as he throws one of his traveling companions overboard to distract a sea monster so he and Murphy can reach land, which is strong foreshadowing for the resolution of this episode. Clarke, after being abandoned by Lexa, finds Octavia under the mountain, and together they find Bellamy, Jasper, and Maya, who is surviving in an air-tight suit that is running out of air.
Tensions only rise as that small team of rebels fails, again and again, to convince Mount Weather's President Dante Wallace to stop harvesting bone marrow from his Skaikru prisoners and let them go. Ultimately, Clarke, Bellamy, and Monty are forced to irradiate Mount Weather in a move that will haunt them for the rest of their lives, earning Clarke the title of Wanheda, or Commander of Death.
Season 5 - "Damocles: Part Two" - 9.7
In the season five finale, we see some resolutions to some plots that have been running for a long time. Madi finally takes her rightful place as Commander and Heir to Lexa Kom Trikru, and we see Bellamy and Octavia escort her at the front of Wonkru into battle against the Eligius prisoners. Clarke resumes her role as savior of her people by single-handedly taking down McCreary using her classic wit and clever rogue-ish ways.
Unfortunately, McCreary does manage to fire off some missiles that end life on Earth before Clarke manages to take him out. As a result, this episode concludes with Clarke and Bellamy listening to a message from Monty and Harper after they wake up from cryo-sleep 125 years in the future. They learn that the Earth is dead and that Monty and Harper sacrificed their lives - stayed awake while the others slept - so that they could get their friends to a new world and give them a second chance.
