You know the image. Even if you aren't a "Trekkie" who spends their weekends debating warp core physics, you’ve seen it. Two men, faces painted starkly—one side obsidian black, the other chalky white. It’s one of the most iconic visuals in television history. But honestly, the Star Trek half white half black episode is a lot weirder and more uncomfortable than the memes suggest.
"Let That Be Your Last Battlefield" aired in 1969. It was the sixties. America was a powder keg. While real-world streets were filled with protests and the civil rights movement was hitting a fever pitch, Gene Roddenberry decided to put a mirror up to the audience. He didn't blink.
The story follows Bele and Lokai. They are the last survivors of a dead planet called Cheron. They’ve been chasing each other through the galaxy for fifty thousand years. Why? Because one is white on the right side, and the other is white on the left side. To Captain Kirk and the crew of the Enterprise, they look identical. To the two combatants, the difference is worth burning a world down.
It’s literal. It’s heavy-handed. It’s classic Trek.
The Casting Behind the Makeup
Frank Gorshin played Bele. You probably know him as the Riddler from the campy Batman series with Adam West. He brought that same twitchy, high-strung energy to Star Trek, but without the giggling. Opposite him was Lou Antonio as Lokai.
The makeup process was a nightmare. Think about it. This wasn't modern CGI or high-end silicone prosthetics. This was 1960s stage paint. The actors couldn't touch their faces. They couldn't sweat too much. Every time they turned their heads, the crew had to make sure the line down the center of their noses stayed perfectly straight. If that line wavered, the whole metaphor collapsed into a joke.
Director Jud Taylor pushed for a theatrical feel. He knew the script by Oliver Crawford was basically a stage play set on a starship. It’s all dialogue. It’s all shouting. It’s two men trapped in a cycle of hatred that neither can actually explain to a rational outsider.

Why the Half White Half Black Aesthetic Was Genius (and Risky)
Television in 1969 was terrified of controversy. Advertisers hated it. Networks ran from it. Usually, if a show wanted to talk about racism, they had to hide it behind a dozen layers of allegory. They’d talk about "green people" vs. "purple people."
But the Star Trek half white half black design was different. It was impossible to ignore what they were talking about. By using the very colors of the racial conflict happening in American cities at the time, the show stripped away the safety of metaphor.
It was a visual gut punch.
Kirk's reaction is the most important part of the episode. He’s annoyed. He’s actually bored by their prejudice. To the 23rd-century mind, the idea that someone would hate another person because of which side of their face is pigmented is insane. That was the "Aha!" moment Roddenberry wanted. He wanted the audience to look at their own prejudices and see how ridiculous they would look to a future civilization.
The Brutal Ending Nobody Expected
Most 60s TV ended with a handshake. The bad guy learns a lesson. The hero gives a speech. Everyone goes back to the status quo.
Not here.

Bele and Lokai don't find peace. They find out their entire planet is dead. Everyone is gone. They are the only two left of their species. And what do they do? They keep fighting. They run back down to the surface of their destroyed world to continue a war that has no meaning and no soldiers.
It’s bleak. It’s one of the darkest endings in the original series. It suggests that some hatreds are so deep they outlive the very reasons they started.
Breaking Down the "Reverse" Logic
The brilliance of the script is how it handles the "difference."
"Are you blind, Commander Spock? Look at me! Look at him!"
"I am looking at you both."
"I am black on the right side!"
"I am white on the right side! All of my people were white on the right side!"
When Bele says this, the audience usually laughs for a second because it sounds so stupid. Then, the realization hits. It's supposed to sound stupid. Star Trek was telling the 1969 audience that their own distinctions—based on skin color—were just as arbitrary as "right-side white" vs. "left-side white."
Cultural Impact and Legacy
People still talk about this episode because it’s so visually distinct. You see it referenced in The Simpsons, South Park, and countless sci-fi parodies. But beyond the parody, it holds a special place in the history of social commentary.

Was it subtle? No.
Was it "cringe" by modern standards? Maybe a little.
But it was brave. At a time when TV shows were losing sponsors for showing interracial couples or discussing civil rights, Star Trek leaned into the discomfort. It used the Star Trek half white half black makeup to make a point that couldn't be silenced.
Behind the Scenes Facts You Might Have Missed
- The Fire Effect: In the final scenes, where the two are chasing each other through the corridors of the Enterprise, the "fire" of their burning world was actually superimposed footage of the Watts riots and other civil rights protests. It was a direct, unmistakable link to reality.
- The Uniforms: Notice that Lokai wears a simple, almost peasant-like jumpsuit, while Bele wears a sophisticated, aristocratic outfit. This added a layer of class warfare to the racial one—Bele was the oppressor, Lokai the revolutionary.
- The Script Changes: Originally, the episode was supposed to be even more graphic, but the censors at NBC were constantly hovering. They managed to keep the bleak ending, which was a huge win for the writers.
What This Episode Teaches Us in 2026
We like to think we’ve moved past this. We haven't. The "us vs. them" mentality is a core part of the human "software" that hasn't been patched out yet.
The episode doesn't offer a solution. It offers a warning. It tells us that if we don't find a way to see the "identical" nature of our humanity, we will end up like Cheron—a graveyard where the only thing left is a pointless chase through the ruins.
Honestly, it’s a miracle this episode got made. It’s loud, it’s angry, and it’s deeply cynical about the human condition. It remains a testament to what science fiction can do when it stops caring about being "polite" and starts caring about being true.
Actionable Insights for Fans and Creators
If you’re revisiting this episode or looking to understand its place in history, here is how to engage with the material more deeply:
- Watch for the Sound Design: Listen to the music during the chase scenes. It’s discordant and stressful, intentionally designed to make the viewer feel the exhaustion of their 50,000-year war.
- Analyze the Blocking: Notice how Kirk and Spock often stand physically between the two aliens. They are literally the "middle ground" that Bele and Lokai refuse to occupy.
- Contextualize the Release: Look up the headlines from January 1969. The episode premiered just months after the assassination of Martin Luther King Jr. Understanding that tension makes the performances feel much more desperate.
- Compare with "The Orville": If you want to see a modern take on this kind of social commentary, look at how Seth MacFarlane’s The Orville handles similar themes. It shows how the "Trek Style" of storytelling has evolved or stayed the same over 50 years.
- Read the Original Script: There are archives online where you can find the early drafts. See how much harsher the dialogue was before the network smoothed out the edges.
The next time you see that black and white face, remember it’s not just a costume. It was a scream for sanity in a world that felt like it was falling apart. It’s why the Star Trek half white half black episode will never truly go out of style.
To get the full experience, watch "Let That Be Your Last Battlefield" (Season 3, Episode 15) on a high-definition screen. The contrast in the makeup is much more striking in 4K, highlighting the physical toll the "paint" took on the actors' expressions and making the visual metaphor even more jarring.
