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 presumably orphaned as the second Praimfaya plagued the Earth. Sometime later, she met Clarke and they developed a daughter-mother bond.

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.

Personality
She is an energetic girl (shouting and jumping at the spaceship). She finds lessons exhausting but is obedient to Clarke.

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