After the underlying tech for M3GAN is stolen and misused by a powerful defense contractor to create a military-grade weapon known as Amelia, M3GAN's creator Gemma realizes that the only option is to resurrect M3GAN and give her a few upgrades, making her faster, stronger, and more lethal.

M3gan 2.0 swaps the original's horror software for a more action-leaning programming that doesn't prove to be an upgrade, although the quippy A.I. remains an amusing mascot of slay.

A full upgrade with a T2 framework, M3GAN 2.0 is a sassy output of camp and chaos that twistedly entertains.

M3GAN 2.0 shifts from horror to action-comedy, focusing on AI themes and character dynamics. Many praise the action scenes, humor, and performances, especially Ivanna Sakhno as Amelia. However, some criticize the convoluted plot, lack of horror elements, and inconsistent tone. The film's exploration of AI ethics and the relationship between Gemma and Cady receive mixed reactions. Overall, while some find it entertaining and an improvement over the original, others feel it fails to meet expectations.
