Honestly, if you were on the internet in 2016, you probably remember the explosion. It wasn't just a TV show moment; it was a cultural earthquake. Lexa from The 100 wasn't supposed to be the face of a global movement, but that’s exactly what happened when Alycia Debnam-Carey stepped onto the screen as the Commander of the Grounders.
She was cold. She was calculating. Then, she was vulnerable.
Most characters in teen sci-fi follow a predictable arc, but Lexa felt like something else entirely. She was a young woman carrying the weight of twelve warring clans on her shoulders, forced to choose between her heart and her people. It’s a classic trope, sure, but the execution was visceral. People didn't just like Lexa; they felt represented by her. Her death in Season 3, Episode 7, "Thirteen," triggered a massive backlash that literally changed how writers' rooms handle LGBTQ+ characters. It’s been a decade, and we’re still talking about it.
The Commander’s Arrival and the Grounder Legacy
When we first meet Lexa, she’s a prisoner. Or so we think.
The reveal that the "meek" girl in the cage was actually the Heda—the Commander—was a masterstroke in subverting expectations. Lexa from The 100 wasn't just a warrior; she was a politician. She introduced the concept of Heda and the Flame, a piece of technology that blended spirituality with artificial intelligence.
She wasn't just leading with a sword. She was leading with the "spirits" of past Commanders.
The complexity of Grounder culture is where the show really hit its stride. You have these tribes like Trikru and Azgeda, governed by the mantra Jus drein jus daun (Blood cries out for blood). Lexa’s entire arc was centered on the revolutionary idea that "Life is about more than just surviving." She tried to break a cycle of violence that had existed for generations. That’s a heavy burden for a character who was barely twenty years old.

Why the Clexa Dynamic Redefined Sci-Fi Romance
The relationship between Clarke Griffin and Lexa—affectionately dubbed "Clexa" by the fandom—wasn't just a subplot. It was the emotional core of the series for two seasons.
It started with a betrayal at Mount Weather. Lexa left Clarke and her people to die to save her own. It was a brutal, pragmatic move that made half the audience hate her and the other half respect her tactical mind. You don't see that often in female leads. Usually, they're written to be "likable." Lexa was written to be a leader.
Their eventual reconciliation was slow. It was earned. They were two leaders from different worlds trying to find a middle ground in a literal wasteland. When they finally kissed, it felt like a shift in the genre. For a brief moment, the most powerful person in this post-apocalyptic world was an openly queer woman whose sexuality was never "the plot." It just was.
The "Bury Your Girls" Trope and the 2016 Backlash
We have to talk about the stray bullet.
Lexa’s death is one of the most controversial moments in television history. Shortly after finally consummating her relationship with Clarke, she was killed by a stray bullet intended for someone else. It was a textbook example of the "Bury Your Tropes" (or Bury Your Gays) cliché, where queer characters are killed off immediately after finding happiness.
The fallout was massive.

- Fans raised over $160,000 for The Trevor Project.
- The "Lexa Pledge" was created, where showrunners promised to do better by LGBTQ+ characters.
- "ClexaCon" was born, becoming a massive convention for queer women in media.
It wasn't just about a fictional character dying. It was about the timing. In a year where dozens of lesbian and bisexual characters were killed off across various shows, Lexa from The 100 became the breaking point. The show's creator, Jason Rothenberg, eventually apologized, but the damage to the show's relationship with its core audience was permanent.
The Nuance of the Flame and Lexa’s "Afterlife"
The genius of the sci-fi element in Lexa’s story is the Flame. It’s not magic; it’s a neural interface.
Because Lexa was a "Nightblood," she could host the ALIE 2.0 chip. This meant that even after her physical body died, her consciousness lived on within the silicon. This allowed the writers to bring her back for the Season 3 finale in the "City of Light." Seeing her dual-wielding swords in a white-washed version of Vancouver (where they filmed) provided some closure, though it was bittersweet.
Her legacy continued through Madi in later seasons. The "spirit" of the Commander became a guiding force, showing that Lexa's influence wasn't just about her time in power, but about the philosophical shift she brought to the Grounders. She changed their world from one of constant tribal warfare to a tentative coalition.
Beyond the Screen: Alycia Debnam-Carey’s Performance
You can't talk about Lexa without the war paint.
Alycia Debnam-Carey brought a specific stillness to the role. Lexa didn't move much. She didn't have to. She used her eyes to convey everything—the pain of losing Costia (her former lover killed by the Ice Queen), the growing affection for Clarke, and the weariness of a leader who knows she's living on borrowed time.

The contrast between her and Clarke was striking. Clarke was all frantic energy and "we have to save everyone," while Lexa was the calm center of the storm. She was the one who taught Clarke that being a leader means making choices that keep you awake at night.
Practical Impact on Representation Today
If you look at shows today, you see Lexa’s DNA everywhere. Characters in The Last of Us or House of the Dragon carry that same weight of "duty vs. desire" that Lexa pioneered for a younger audience.
She proved that a female character could be ruthless, mess up, betray the protagonist, and still be the hero of her own story. She wasn't a sidekick. She was the mountain.
Actionable Takeaways for Fans and Writers
If you’re revisiting the series or writing your own characters, there are a few things Lexa teaches us about high-stakes storytelling:
- World-building through language: The use of Trigedasleng (the Grounder language) added a layer of immersion that made Lexa’s world feel ancient and lived-in.
- Consequences matter: Lexa’s betrayal at Mount Weather wasn't hand-waved away. It took an entire season for Clarke to forgive her, which made their bond stronger.
- The power of visual branding: The "raccoon" war paint and the red bindis became iconic. When creating a character, a distinct visual silhouette is everything.
- Respect the audience: The Lexa controversy taught the industry that fans are hyper-aware of tropes. If you're going to kill a beloved character, the "how" and "why" matter as much as the "when."
Lexa from The 100 remains a masterclass in character design. She was a warrior, a lover, and a tragic figure who somehow managed to be larger than the show that created her. Whether you're a long-time fan or a newcomer wondering why your Twitter feed is still full of Heda fanart, her impact on television history is undeniable.
To really understand the weight of her character, watch the Season 2 episode "Contents Under Pressure." It’s where the mask first slips, and you see the girl behind the Commander. It's the moment the show stopped being a Lord of the Flies clone and became a genuine political drama. Lexa wasn't just a character; she was the catalyst for the show’s best years.
