Madi Griffin

Madi is a recurring character in the fourth and fifth seasons. She was portrayed by Imogen Tear in her debut appearance in Praimfaya. Beginning with Eden, she is played by Lola Flanery.

Madi is a young Nightblood that met Clarke Griffin sometime after Praimfaya.

Early Life
Madi was born on Earth and is a member of the Shallow Valley. She is a Nightblood and was orphaned as the second Praimfaya plagued the Earth.

58 days after Praimfaya, she met Clarke. Thinking that Clarke is a Flamekeeper scout, Madi led Clarke into a trap and attacked her. However, after realizing that Clarke is also a Nightblood, Madi stopped the attack and ran away. Overnight, Madi stole Clarke's possessions. The next morning, Clarke found Madi spear fishing in a nearby creek, but Madi once again runs away from her. Later, Clarke manages to lure Madi by drawing an image of her.

Over the next six years, Madi and Clarke's relationship continues to develop and they form a daughter-mother bond. Clarke teaches Madi to speak English, drive the rover, and about the 100's history.

Throughout the Series
In Praimfaya, Madi is asleep in the rover and is later woken up by Clarke. Upon being woken up, she expects to finally meet Clarke's friends from the Ark but is confused when she sees the Eligius Corporation ship fly in instead. Clarke tells her that it is not her friends and tells her to get the rover out of sight and to load the guns.

In "Sleeping Giants," Madi and Clarke are being hunted down by Diyoza's prisoners. When Clarke gets injured, she shows Madi a place to hide, just before Clarke is captured and tortured. After realizing that Madi's hiding place is compromised, Clarke pleads with Diyoza to spare Madi's life in exchange for her co-operation. When Bellamy and the survivors from the Ark arrive, Madi runs to welcome them and tells them about Clarke. She leads Bellamy to the church where Clarke is being interrogated. She goes into hiding with the rest of Bellamy's team.

Madi and the gang finally join with Octavia and Wonkru in "Shifting Sands." She is immediately fascinated by Octavia, thanks to all the heroic stories Clarke has told her. When Octavia asks how Madi survived the Praimfaya, Clarke lies to her that Madi got synthetic Nightblood just like Clarke.

In "Exit Wounds," Clarke reminds Madi that they can never let anyone know that she's a born Nightblood. If the Grounders found out, some would want her to become Commander instead of Octavia, leading to a power struggle which would put Madi's life in danger. Unfortunately, Gaia and Niylah quickly figure out Madi's secret. To protect Madi, Clarke decides to join the defectors and take Madi to the Valley with her where Madi would be safe from Octavia. Madi disagrees with Clarke because going back to the valley could get Clarke killed. So, she sneaks and runs to Octavia the last minute, making it impossible for Clarke to go ahead with her plan. Madi tells Octavia everything about herself and Octavia embraces her. Octavia performs a blood ritual initiating Madi as Wonkru. Clarke finds them and Madi assures her that everything is okay. Octavia promises Clarke that she will protect Madi and her secret. Octavia gives an order that Madi should start training immediately to prepare her for battle.

Madi starts her official training in "Acceptable Losses". Worried that Madi might still be seen as a leadership threat, Clarke asks her to intentionally underperform. But Madi's acting is too obvious and Gaia figures out that she's holding back on purpose. Gaia agrees with Clarke's thinking that Madi should hold back so that she doesn't endanger herself. She assures Madi that as the Flamekeeper, it's her job to protect her. She shows Madi the Flame she's been keeping. Madi looks at it and is fascinated by it. Gaia tells that she will serve Octavia faithfully but that as Flamekeeper she must still ensure the Flame's succession. During the next training, Octavia is watching. At first, Madi holds back, but she changes her mind and gives it her best, defeating Ethan. She impresses Octavia but disappoints Clarke and Gaia. Octavia orders for Madi to be given a real sword, ready to fight for Wonkru.

Personality
She is an energetic girl, shouting and jumping at the spaceship. She finds lessons exhausting but is generally obedient to Clarke. Madi is shown to deeply care about Clarke, trying to help her against the Eligius prisoners multiple times. Madi is at first cautious about killing the Eligius prisoners, but she is well trained in combat. She is fierce and objects when Clarke tries to hide and protect her. She easily trust Bellamy and the other Spacekru. She sees Octavia as her hero and was very excited to meet her. She wants to impress Octavia and goes to her regardless of Clarke's objections. Madi is also shown to be forgiving – she offers Ethan a hand after beating him even though he previously mocked her. Despite her obvious strengths, Madi tends to not think of the consequences of her actions, which I personally think is quite StUPid.

Physical Appearance
Madi has pale skin, braided light brown hair and blue eyes. She is seen wearing a black beanie and Grounder clothing.
