List of The 100 characters

The series stars Eliza Taylor as Clarke Griffin, as well as Paige Turco, Thomas McDonell, Eli Goree, Marie Avgeropoulos, Bob Morley, Kelly Hu (who was dropped after the first episode due to budget cuts), Christopher Larkin, Devon Bostick, Isaiah Washington, and Henry Ian Cusick.

The Mountain Men are responsible for creating the acid fog that has killed numerous outsiders, as well as the barbaric Reapers who helped them capture Grounders for their blood-harvesting program.

In 2156, Shaw piloted the transport craft Gagarin and lands Diyoza with a party of prisoners in the Shallow Valley, which is apparently the only habitable place left after the radiation wave Praimfaya in the fourth-season finale.

In "Anaconda", its revealed that the Disciples were originally the Second Dawn cult who had started worshipping Bill Cadogan by the time that Becca Franko had arrived on Earth two years after the first nuclear apocalypse.

Cadogan explains to Gabriel Santiago, Niylah and Jordan Green that upon arriving on Bardo, the Disciples found logs left by the native Bardoans describing their use of the Anomaly Stone.

She is portrayed as relatively benevolent, but has been shown to act ruthlessly to fight or kill in order to protect her people if there are no other options, and she possesses natural leadership qualities with the help (and early on, the opposition) of Bellamy.

After killing the entire Mountain Men population to save her fellow Sky People, Clarke becomes known in Trigedasleng as Wanheda (literally "The Commander of Death") and is sometimes also called Mountain-slayer.

This transforms her into a strong but personally troubled heroine in the series, as she continues to struggle to reunify humankind by maintaining the uneasy peace between the Arkers and some of the Grounders, and between groups among her own people.

He was arrested for being a spacewalker and wasting the Ark's limited oxygen supply, but it was revealed that he was innocent and had taken the fall for Raven, his girlfriend, to ensure she did not ruin her engineering career or get floated.

As a result of his actions, the Grounders demanded retribution before they will agree to a truce between them and the Sky People, leading Commander Lexa to sentence Finn to death by a thousand cuts.

It was his expert knowledge of botany that made him a valuable ally to Clarke, as she was tasked as the 100's medic due to her previous experience as the daughter of a doctor and needed herbal medicines to treat the ill and injured members of their community.

Portrayed by Marie Avgeropoulos (and by Olivia Steele Falconer as child) Octavia Blake[2] is Bellamy's younger sister – a rare relationship given the Ark's one-child rule.

It is intensified when she discovers Clarke knew about the bombing of Tondc, did nothing about it, and allowed all those Grounders to die after the events of Mount Weather (even telling Indra that she will not leave behind Bellamy and her friends).

Having been returned to Bardo, Octavia regains her lost memories and witnesses Bellamy's apparent death before being rescued by Echo, Hope and Gabriel for whom five years has gone by after getting stuck on Skyring themselves.

After Indra finally kills the Dark Commander, Octavia steps between the two sides and gives a speech encouraging them to embrace peace with each other, acknowledging her own mistakes and reminding them that they are all humanity.

He eventually betrays his mother and Pike in "Stealing Fire" by helping Kane, Octavia, Harper, Miller, and Sinclair escape by feeding members of the Ark Guard faulty intel and distracting them.

In "Red Sky At Morning", Monty has sex with Harper in Arkadia, and is forced to delete and essentially kill his mother for a second time by wiping her memory from the City of Light.

When the Lee family from Sanctum seizes control of Eligius IV, Raven awakens Charmaine Diyoza from cryosleep and retakes the ship with her and Madi's help, leading to the deaths of all but one of the hijackers.

With the armor's help, Raven leads her friends on a rescue mission for Bellamy, Octavia, Echo and Hope, but accidentally directs them to the wrong planet, an icy world called Nakara with no sign of any way to reopen the Anomaly back.

During the final battle with A.L.I.E., Murphy plays a vital part by manually pumping the brain-dead Ontari's heart to keep a blood transfusion to Clarke going so that she can use the Flame to destroy A.L.I.E.

After the prisoners suffer a fatal dose of radiation, Raven, not willing to trust them to do the right thing when faced with certain death, lies to them and tricks Murphy into helping, relying on his sense of self-preservation.

Russell subsequently spent the next twenty-five years working with Josephine's boyfriend Gabriel Santiago to find a way to resurrect those that they lost, eventually succeeding through Mind Drives and Nightblood hosts and gaining a form of immortality.

After Clarke's friends began fostering rebellion, leading to Simone's death, Russell abandoned all restraint and nearly burned them at the stake before John Murphy offered a way to restore the Primes using bone marrow transplants to recreate Nightblood.

After receiving word that her adopted mother Clarke Griffin had been killed in order to resurrect Josephine Lightbourne, Madi banishes Gaia and agrees to follow the Dark Commander to get revenge against the Primes.

Due to Madi's actions and Bellamy kidnapping Josephine after learning that Clarke was still alive and trapped inside of her own body, relations between the Primes and the Earth people fall apart and they are imprisoned.

Indra promises to kill Sheidheda herself when the time comes and has Russell's Mind Drive painfully removed by Eric Jackson so that the Dark Commander can not be resurrected again when he dies.

However, Madi manages to slash out his right eye with a knife while Murphy and Emori lead the surviving Sanctummites into hiding to prepare to fight back against the Dark Commander's reign.

Sheidheda's attack leaves Gabriel Santiago mortally wounded, but the Dark Commander is defeated in combat by Indra and Gaia and forced to flee empty-handed in order to survive.

However, Gabriel developed moral concerns about their actions, particularly sacrificing innocent people to save themselves and destroyed the Nightblood embryos in an attempt to stop the resurrections, escaping with the help of Ryker Desai.

However, Hope was captured trying to rescue her mother and forced by the Disciple leader Anders to inject Octavia with a locator tag when she was eventually pulled through the Anomaly in exchange for Diyoza's life.
