When Arcane dropped on Netflix, it didn't just break the "video game adaptation curse"—it vaporized it. Most people expected a flashy commercial for League of Legends. What we got instead was a Shakespearian tragedy fueled by neon, shimmer, and some of the most gut-wrenching vocal performances in modern animation. Honestly, the cast of Arcane Season 1 is the secret sauce. You can have the best ink-and-paint style in the world (shoutout to Fortiche), but if the voices don't land, the characters are just pretty puppets.
The casting director, Libby Sharpe, didn't just go for big names to slap on a poster. She found people who could actually breathe through the microphone.
Hailee Steinfeld as Vi: Not Just an Action Hero
You probably know Hailee Steinfeld from Spider-Man: Into the Spider-Verse or Hawkeye. She’s everywhere. But in Arcane, she does something different. Vi isn't just a brawler; she’s a girl who grew up too fast in a literal hole in the ground called Zaun.
Steinfeld brings this rasp. It's subtle. You hear it when Vi is trying to be tough in Stillwater Prison, but you also hear it crack when she sees Jinx for the first time in years. It’s a physical performance. Reportedly, the actors recorded a lot of their lines together, which is rare in animation. That’s why the chemistry feels so raw. When Vi yells, it’s not just "loud volume"—you can feel the strain in her chest.
Ella Purnell and the Chaos of Jinx
If Vi is the heart, Jinx is the shattered glass. Ella Purnell—who you’ve likely seen recently in the Fallout series—had the hardest job in the entire show. She had to take Powder, a sweet, clumsy kid, and turn her into a manic, blue-haired terrorist without losing the audience's sympathy.
It’s easy to do "crazy." It’s hard to do "traumatized and hallucinating while trying to seek approval from a father figure." Purnell’s voice for Jinx is erratic. She jumps from a whisper to a scream in a single breath. The way she delivers lines like "I thought you could love me like you used to" is devastating. It's not just a cartoon character talking; it sounds like someone having a genuine mental health crisis.

The Men of Piltover and the Underworld
Let's talk about Silco. Jason Spisak. If there was an Emmy for "Voice Acting That Makes Your Skin Crawl But You Still Kind of Agree With the Villain," he would have won it. Spisak has been in the industry for years, doing voices for Young Justice and The Joker, but Silco is his masterpiece. He speaks in this low, gravelly oily tone. He never has to shout because he knows he owns the room.
Then you have the contrast in Piltover.
- Kevin Alejandro as Jayce Talis: The "Golden Boy." Alejandro brings a certain earnestness that makes you almost forgive Jayce for being a bit of a tool sometimes.
- Harry Lloyd as Viktor: This is the fan favorite. Lloyd (who played Viserys in Game of Thrones) gives Viktor a heavy, soulful accent that sounds weary. He’s a man literally running out of time, and every line sounds like he’s exhaling his last bit of energy into his research.
The dynamic between these two is the backbone of the "Topside" plot. It’s a bromance that turns into a philosophical war, and without Lloyd's vulnerability, Viktor’s descent into "the Glorious Evolution" wouldn't hit nearly as hard.
Why the Cast of Arcane Season 1 Hits Different
Most animated shows record the dialogue, and then the animators match the mouth movements. With the cast of Arcane Season 1, Fortiche (the studio) actually looked at the actors' facial expressions. When Caitlyn—voiced by the brilliant Katie Leung (Cho Chang from Harry Potter)—looks nervous, it’s often because Leung herself was making those micro-expressions in the booth.
Caitlyn Kirby is an interesting one. She starts as this sheltered Enforcer "Piltie," and Leung plays her with a very prim, proper British inflection. But as she spends more time with Vi in the slums of Zaun, that stiffness starts to melt. It’s a masterclass in vocal character arcs.

Supporting Players Who Stole the Show
You can't talk about this cast without mentioning Mel Medarda, voiced by Toks Olagundoye. She has this regal, commanding presence that makes the Council scenes actually interesting instead of just "boring politics." And then there’s Vander.
JB Blanc. The man is a legend. He voiced Braum in the game, but for Arcane, he became Vander, the "Hound of the Underground." He sounds like a mountain that’s tired of being hit by the wind. When he dies in Episode 3, you don't just feel sad because of the plot; you feel sad because that deep, comforting voice is gone from the show.
Dealing With the "League" Baggage
There was a lot of skepticism early on. Fans of the game were worried. "Wait, why isn't the original voice actor from the game playing Jinx?" (That would be Sarah Anne Williams, who is incredible, by the way).
The reality is that Riot Games wanted to ground the show in a more "cinematic" reality. The game voices are meant to be heard over the sound of explosions and clicking mice. They are exaggerated. The show needed intimacy. By bringing in this specific cast of Arcane Season 1, they bridged the gap between a MOBA and a prestige HBO-style drama.
The Complexity of Heimerdinger and Ekko
Reed Shannon as Ekko was a stroke of genius. He brings a "street-smart but brilliant" energy to the Firelight leader. His fight scene with Jinx on the bridge—which is mostly silent except for the music—relies heavily on the grunts, breaths, and the history between the two actors' performances.

And Mick Wingert as Heimerdinger? He managed to make a fuzzy yordle scientist sound like a thousand-year-old man burdened by the weight of history. It’s a delicate balance. You want him to be cute, but you need to respect his authority.
The Sound of Zaun vs. Piltover
The audio engineering team did something clever here. The voices in Piltover often have more "air" around them—they sound crisp, clean, and expensive. The voices in Zaun, especially characters like Sevika (voiced by Iranian-American actress Shoreh Aghdashloo, who has the most iconic raspy voice in Hollywood history), sound heavy.
Aghdashloo as Sevika is terrifying. She doesn't say much, but when she does, it sounds like she’s chewing on gravel. It’s perfect for a woman with a mechanical arm who spends her days in smoky bars.
Actionable Takeaways for Fans and Creators
If you’re looking at why this cast worked so well, it boils down to three things you can actually observe if you re-watch the show:
- Vocal Texture: Don't just listen to the words. Listen to the breathing. Notice how Jinx breathes faster when she's panicked.
- Chemistry over Fame: While there are stars here, they were chosen because their voices contrast. Vi is low and grounded; Jinx is high and erratic.
- Acting, not "Voice Acting": These performers approached the script like a live-action drama. They didn't do "cartoon voices."
To truly appreciate the cast of Arcane Season 1, go back and watch the "Dinner Scene" in the finale. It’s basically a stage play. Three characters in a room, talking. No big fight for ten minutes. Just raw acting. That is where the show won its Emmys.
If you haven't yet, check out the "Bridging the Rift" documentary series on YouTube. It shows the behind-the-scenes footage of these actors in the booth. Seeing JB Blanc tear up while recording Vander’s final scenes explains exactly why the show feels so "human" despite being about blue magic and hextech.
Next Steps:
- Watch the "Bridging the Rift" documentary on the Riot Games YouTube channel to see the recording sessions.
- Re-watch Episode 3 and Episode 9 back-to-back to hear the specific vocal evolution of Powder into Jinx.
- Look up Shoreh Aghdashloo’s other work in The Expanse if you want more of that incredible Sevika-style grit.
