|“||(cue O Fortuna) The R.E.G.I.S Mk.5 is invincible. No weapon forged by such a primitive species can defeat the REGIS, which is invincible.||„|
|~ R. E. G. I. S Mark 5|
R. E. G. I. S is short for Replicant Engineered for Galactic Infiltration and Sabotage and is a machine built to destroy planets. It was deported to be dumped into a black hole by an alien ship. This was until Coop accidentally knocked into the ship's cloaking device making it fall to Earth. He begins absorbing metals causing him to grow and become more powerful by fusing it with his nanotechnology. Coop's attempts to beat him only made him grow more and more powerful, to the point that the entire city was almost destroyed. REGIS eventually gained the upper-hand by multiplying until Coop's friend Jaime finally discovered that R. E. G. I. S Mark 5 was solar-powered, so he managed to destroy R.E.G.I.S. by covering the sky with smoke from his overheating Megas. Only the eye of R.E.G.I.S remained, which was taken by a kid. This piece lights up in the credits, showing that he is still very much alive.
