Lexa kom Trikru

Lexa kom Trikru, more commonly referred to as Commander Lexa, was a character on the CW television series The 100 portrayed by Alycia Debnam-Carey. She was in a brief romantic relationship with the protagonist of the show, Clarke Griffin, despite the two being on opposite sides of the conflict between the Sky People and the Trikru (known as "Grounders" by the Sky People).

Prior to the event of the series, Lexa was in a romantic relationship with fellow Grounder Costia. Costia was ultimately captured, tortured, and killed by the Ice Nation at the bequest of Queen Nia, who tortured Costia in an attempt to learn Lexa's secrets. After this, Lexa became closed off and staunchly believed love to be a weakness.

Lexa was eventually killed off, much to the disappointment of fans.
