The Prism Robots (プリズムロボット, Purizumu Robotto) are a team of seven humanoid robots.
The Prism Robots were created roughly 40 years before the present in top secret by an alien tribe during their stay on Earth, using their own highly advanced technology that was unheard of and not known to humans at the time. Thus, their reasons for manufacturing the Prism Robots and devoting a prismatic arrangement color scheme are unknown.
The Prism Robots they created were primarily colored one of the colors of the rainbow along with black. Their eyes are empty black sockets with small LED-like eyes colored the Prism Robot's distinct color (which turn off when the Prism Robot would blink or closing their eyes. The LED eyes slide across the socket to emulate an eye turning and are protected by a transparent shielding placed over each eye. Their faces are capable of showing a very wide range of emotions via both the eyes and mouth, the latter containing a fully functional tongue colored to match the Prism Robot along with artificial saliva glands. Scattered across their bodies and armor are additional LED lights that shine in other colors colors. Lastly, they were intended to weaponize each of the seven Sins during their creation.
However, a major programing error gave each of them destructive personalities matching the Sins they were built around and their voices- which once were perfectly akin to a normal human's speech, became distorted and robotic in short time (with the yellow "Greed" robot, Phasmor, developing the most broken of the robots' voices). Unable to fix the robots and prevent them from growing hostile and turning on the alien tribe and eventually the rest of the world, the aliens sealed up the robots in suspended animation for eternity in a deep underground base located near Area 51 in Nevada and flew back into outer space, never to return and leaving the robots isolated, lifeless, and unaware of their current situation. A near-finished project was also abandoned and sealed up with the robots- personal mechas that the robots could enter and drive to combat big threats, each catered to take advantage of the best traits of their riders alongside sporting their riders' signature color.
40 years later, an intelligent robotics engineer named Jonathan found his way into the base and awoke them from suspended animation, releasing the seven robots and granting them access to their powers and allowing them to finish and use their personal mechas while looking up to Jonathan as a leader figure. After each member experienced encounters with Aozora leading to their destruction one by one, Jonathan, using the original blueprints and design documents left in the Prism Robots' base from 40 years ago, reconstructed each Prism Robot and restored their memories with the glitches and programing errors they initially had- with the only change made being their levels of aggression so they wouldn't resort to the destruction of the country if left unchecked. After the deed was done, Jonathan activated them all and left the base immediately without a word- reconsidering his actions and feeling regret after letting loose seven living tools of destruction, praying they don't start up another nation-wide attack.
