Nearly every supporting character on The 100 did plenty to advance the story and help fill in the universe’s blanks but not all of them were loved.
Fans had plenty of thoughts about Clarke, Bellamy, Octavia, and the other central characters. But, they were not the only ones to make an impression. Those that were not considered to be the main characters also made an impact on viewers. Nearly every supporting character did plenty to advance the story and help fill in the universe’s blanks. Since some had been included so early on in the show, fans couldn’t help but root for their survival.
Not everyone had that kind of effect, though. Sometimes supporting characters hurt the story or make wrong choices. Other times, a character may not have felt narratively necessary to the overall plot.
Lincoln is the first Grounder who interacts with the hundred and tries to get Trikru to have peace with the delinquents. Between his wish for peace and his relationship with Octavia, Lincoln gained a heavy following.
Lincoln was a good man, always wanting to fit in with Skaikru and help Octavia understand his ways. Unfortunately, Lincoln’s life was cut short. Lincoln died for protecting his people, and his death left Octavia spiraling. In later episodes, Octavia honors Lincoln by painting his tattoo on her face for war paint.
Hated: Dr. Tsing
Cage Wallace may have been the mind behind the horrifying activities going on in Mount Weather, but he didn’t do it alone. Dr. Tsing joined Cage’s awful endeavors, pushing harder for harmful actions. Dr. Tsing was responsible for extracting bone marrow from the forty-seven. As she hurt them, Dr. Tsing would explain to the forty-seven how important they were.
Later on, the delinquents got their revenge. Dr. Tsing died of radiation exposure. In her last moments, Dr. Tsing was surrounded by Jasper, Monty, and Harper. Jasper delivered the same cruel line she had said to them, “I hope you know that you’re incredibly special to us.”
The exiled Prince turned King of Azgeda is a fan-favorite. Only on the show for two seasons, Roan made his first impression by kidnapping Clarke, although he eventually became a friend. Roan took over as a leader while Skaikru searched for ways to save the human race.
He was a significant part of the plot and allied with Octavia during the Conclave. Roan didn’t survive the Conclave, killed by Luna and the black rain. However, actor Zach McGowan reprised his role during “From The Ashes” to speak to Echo in the form of the Anomaly.
Hated: Bill Cadogan
During the first apocalypse, Cadogan was in charge of the Second Dawn Bunker. “Anaconda” gave an inside look as to who he was while also portraying his daughter, Callie, to be a major player in the creation of Grounder culture.
Cadogan became obsessed with the Anomaly Stone and refused Becca and Callie’s wish to inject everyone with Nightblood to live on the ground. When with his family, Cadogan clearly favored Callie over his son, Reese. He was even willing to let his wife die. Two centuries later, Cadogan is still alive and known to all those on Bardo as “The Shepherd.”
Emori made an entertaining first impression by making life harder for John Murphy. But, Emori and Murphy eventually got together, and after Praimfaya, Emori became part of the group. Six years after going to space, Emori is a firm part of Spacekru and has a solid friendship with Raven.
“The Dying Of The Light” uses plenty of screentime to show how essential Emori is to Murphy and Raven. Their storyline revolves around continually reminding Emori how important she is to them. Fans hoped that she would survive the final season.
Narratively, one of the biggest problems with Sheidheda is that fans couldn’t figure out why he was still alive after a while. There were several opportunities to kill him that fail. Yet, no one could determine what narrative purpose he had and why he continued to survive.
While Sheidheda’s actions brought out Murphy’s hero side and a leadership attribute in Indra, there isn’t much else he’s good for. In the end, Indra finally accomplishes killing Sheidheda, blasting him out of existence.
Indra first appeared in season two, and she has been essential to the plot ever since. Octavia relied on Indra and her teachings to help Octavia get through life. While their relationship may be strained during her Blodreina years, Octavia and Indra supported each other.
Indra was a brilliant fighter, and fans were constantly rooting for her. However short as it was, Indra’s rise to leader of Wonkru was an epic moment of growth for Indra and a fan-favorite event.
While Kane and Abby were learning from Clarke and gaining Grounder allies, Charles Pike’s group was not so lucky. Pike’s group was attacked by Grounders, causing Monty’s father’s death. Afterward, Pike looked at Grounders as the enemy instead of a potential ally.
This mentality did not do good for anyone and instead caused hundreds of Grounder deaths and uprisings within Arkadia. The final straw for Pike was when he killed Lincoln, which Octavia got revenge for later. When Octavia looks within, she is confronted by her mind’s memory of Pike.
It is no surprise that Lexa was one of the most loved supporting characters. Lexa was the Commander willing to ally with Clarke to save their people from Mount Weather. Lexa was considered to have been the Commander to unite all the clans.
She was an excellent fighter and known to think differently than previous Commanders. Lexa’s relationship with Clarke was also heavily supported by fans. Lexa was one of the most influential people in Clarke’s life, and her appearance is used to speak to Clarke during “The Last War.”
Finn is the first of the main delinquents to die, not making it past the middle of season two. He makes an intriguing first impression, reminding Clarke of her father and wishing for peace. Finn doesn’t want to fight, but his nice guy appearance is ruined as it becomes clear that Finn has a girlfriend on the Ark.
Finn never mentions Raven to Clarke, making things uncomfortable when Raven lands on the ground. He continues to obsess over Clarke and not be as invested in Raven. Finn only becomes worse in season two, killing several innocent Grounders while he spirals during Clarke’s absence.
