Alphas are larger, blue variants of Drones, and are psychologically-interconnected to the Omega; if an Alpha Mimic dies, a response is instantly triggered in the Omega that causes it to turn back time, while retaining knowledge of the potential future. This mechanic allows the Mimics to adapt to any combat strategy, since they are capable of continuously turning back time until a favorable outcome is reached. Being the commander units, they can command lower unit like Drone. After death, they petrify into obsidian and lose the blue glow.
According to Dr. Carter, Alpha Mimics are rare, only appearing about 1 in 6.18 million times.
Alpha is composed of a mass of black tentacles with blue light glowing out of their insides and facial features. It's bigger than a Drone and can change it's shape to the situation. Their blood is also highly acidic as its melted Cage's face when it came into contact.
- Dr. Carter estimates the occurrence of alpha mimics to be about one in 6.18 million. This could be a reference to the golden ratio, which is approximately 1.618 to 1 (or 1 to 0.618), and is found in the structures of some plants and animals.
