Mimics are a creature born of technology and flesh eater, made in the facilities as a successful experiment. So successful they were a big factor in escaping the facilities and being freed into the wild.

• You could say they are the successful version of flesh eaters, as they are 60-85% organic, with the rest being mechanical parts/replacements/enhancements
• Anything over 85% is probably just a flesh eater with quite literally some screws loose
• Mimics are known for tricking humans and killing them when their guard is down, letting one inside your home is a death sentence
• In space they evolve to eat aliens and settle for drinking their blood
• Their intelligence varies from mimic to mimic, it depends on where their priorities are. some are better at social interaction, some are experts at vocal mimicry, some would rather beef up and focus on taking out their prey in one go, some prefer a smaller build to run faster or disguise themselves as a younger human. some mimic a seductive build for better allurement, it varies. 
• Usually they have one unique ability or quality to them to make them better at catching their prey. the helmet mimic in the first pic can use toxic gas to blind/paralyze its prey before eating, HG has a storage ability, able to store his food in his stomach for later or simply hold on to it so he can digest it later. In the first GBot mimic pic, it has a stomach mouth to eat faster and a brain in the pelvis area to protect better, etc
• They reproduce with other mimics (astronaut mimics evolve to reproduce with aliens) and can only have one-two mimic spawn in a lifetime.

So far there are

Helmet Mimics

• Mimics that took the design of a helmet or simply used a real helmet to cover their ‘face’, and dress up with human clothes. It should be noted some helmet mimics dont bother dressing up. They eat flesh (human/animal) to survive but its the blood theyre really after, the rest is just the vegetables to the fruit. Some prefer vegetables over fruit some like both, it varies.

GBot Mimics

• Mimics that take the designs of Griva’s robots. It’s one of the reasons why Griva has express orders to kill any mimic GBots come across. A GBot Mimic will kill a human in seconds, especially those clueless of their existence and tactics.

Knight Mimics

• Mimics that took up the look of knights. These mimics are a part of the 'cooperative creatures’ willing to help make the world a safer place for humans, their livestock, and the natural ecosystem before the Research Facilities. They make a point to only eat bugs and mutant fauna, humans are off the menu.
• These Mimics were given the OK by Griva, and therefore are allowed to help and interact with humans. Any Knight Mimic that breaks the moral code of eating human is shunned and killed by either the humans’ relatives/friends, the locals, or simply the GBots.

Astronaut Mimics

• Mimics that took the functions and design of astronauts/GBot astronauts and are in space. Looking for alien life to eat/evolve from. its possible they could become their own alien race soon too
