How Was Stephanie Kerbis Confirmed as Vyper’s Voice Actor?
Stephanie Kerbis confirmed she’s the voice of Vyper in Deadlock in a TikTok she posted back in September 2025. You can find more of her stuff on her TikTok if you want to check it out.
IMDb also credits her as Vyper in Deadlock. So, unlike some of the other voice-actor mysteries in the game, you don’t have to sit around and compare clips to figure it out. This one’s settled.
I think one of the reasons why she’s so beloved within the community is Stephanie Kerbis’ performance. Her delivery and the way she brings the character’s lines to life are awe-inspiring.
Best Vyper Voice Lines in Deadlock (With Audio)
If you want to hear Stephanie Kerbis’s work for yourself, the Deadlock Voice Line Viewer has a bunch of Vyper’s recordings and transcripts, which include her conversations with other heroes.
One of the funniest bits is how hard she goes for Lash. When he’s above her, she can just straight-up say:
“Hey, my future husband’s up there!“
Then there’s her back-and-forth with Abrams. He asks how she got out of jail and Vyper just fires back by questioning why anyone would ever expect her to be released in the first place. Abrams doesn’t sound thrilled with that answer, though.
“Who lets anyone out of jail? We’re gonna have a blast, Abe. Don’t sweat it.”
Her hero-selection lines are just as unhinged. I particularly like how she roasts Infernus for turning into a cocktail-slinging softie, then immediately panics that he might overhear it.
“Infernus used to be hard, now he’s just a bitch slinging Mary Pickfords to other bitches… oh god, don’t tell him I said that.”
In another one, she jokes that she never gets the feeling something bad is about to happen, which apparently explains why she keeps ending up in jail.
“You ever get that feeling that something bad is going to happen? Yeah, so I don’t, that’s why I end up in jail so much.”
Her criminal history pops up again when she upgrades her dagger ability. She proudly says, “And my PO thinks I don’t have marketable skills…”
Her deadpan delivery makes it even funnier, to say the least. PO is short for parole officer, by the way.
Sometimes the whole joke is just in her delivery. When she spots an enemy with Metal Skin, she yells, “They got metal skin!” The way she shouts it makes even a basic warning hilarious.
And now she, as Vyper, compares the amount of poison she’s about to unleash to her mom’s reaction after she found out about the life insurance policy. That family history is a lot to unpack, to be honest. “I’m gonna be slinging more poison than my mom after she found out about the life insurance policy.”
It’s that mix of stupid decisions and perfectly timed delivery that makes Vyper so fun to listen to. Kerbis can turn even a basic gameplay warning into something that sticks with you.
