The' 'P.I.N.G.A.S. (short for Pulverizer of Immortals and Neutralizer of Gods, Animals, and Space) is a massive space station constructed by Dr. Robotnik over the course of centuries. Mounted with a cannon allegedly powerful enough to kill an Undefeatable, it was designed as the ultimate weapon against that pesky hedgehog as well as the Undefeatables themselves. It was first started some time in the early 2010s and finally launched into space in 2401.
