M3GAN 2.0 (2025) Cast & Characters Guide

M3GAN 2.0 Synopsis

Two years after M3GAN, a marvel of artificial intelligence, went rogue and embarked on a murderous (and impeccably choreographed) rampage and was subsequently destroyed, M3GAN’s creator Gemma (Allison Williams) has become a high-profile author and advocate for government oversight of A.I. Meanwhile, Gemma’s niece Cady (Violet McGraw), now 14, has become a teenager, rebelling against Gemma’s overprotective rules.

Unbeknownst to them, the underlying tech for M3GAN has been stolen and misused by a powerful defense contractor to create a military-grade weapon known as Amelia (Ivanna Sakhno; Ahsoka, Pacific Rim: Uprising), the ultimate killer infiltration spy. But as Amelia’s self-awareness increases, she becomes decidedly less interested in taking orders from humans. Or in keeping them around.

With the future of human existence on the line, Gemma realizes that the only option is to resurrect M3GAN (Amie Donald, voiced by Jenna Davis) and give her a few upgrades, making her faster, stronger, and more lethal. As their paths collide, the original A.I. bitch is about to meet her match.

M3GAN 2.0 (2025) Cast & Characters Guide

Allison Williams as Gemma

Back from the chaos of the first film, Allison returns as Gemma—forging new rules in AI ethics and rocking a snazzy exo-suit. She’s still juggling science and guilt, now pitching AI oversight while secretly building a robo-body armor. You might know her from Get Out or Girls, so she’s well-versed in blending horror with real drama syfy.com+1whattowatch.com+1.

Violet McGraw as Cady

Now 14 and full-blown teen rebellion, Violet’s Cady is the sweet heart of the story. She misses M3GAN more than homework—and let’s be honest, we all would. This kid acts in Black Widow and Hill House, and you can already feel her getting ready to steal every scene .

Amie Donald & Jenna Davis as M3GAN

Our favorite killer doll returns with a power-up—and a brand-new skill set. Amie handles the moves (dance skills, martial arts, you name it), and Jenna adds the sassy voice (she’s a TikToker and singer). Expect epic fight choreography and that iconic, slightly unsettling doll persona making a major comeback.

Ivanna Sakhno as AM3L1A

New to the franchise, Ivanna is playing AM3L1A—a military-built robot with some serious attitude. This is no mindless killing machine—she’s questioning her purpose, and she’s not taking orders. You’ve seen Ivanna in Pacific Rim Uprising and Ahsoka, so she’s well-versed in sci-fi badassery.

Quick Fun Fact!

The M3GAN 2.0 teaser debuted at the Grammys, dancing to a track called “Femininomenon”—because, duh, even killer dolls need their spotlight moments.
