Cratermass had been creating the gateway for some time, hoping to visit other planets. The teleporter itself was complete, but Cratermass was unable to finish the data for his project. He was then distracted when Amy Rose and Tekno the Canary crash-landed on Planet Earth. Amy wanted a way home, so Cratermass presented the gateway, only to reveal his lack of compiled data. Fortunately, Tekno was computer-literate enough to understand the technology and began to add her input. Unfortunately, she was interrupted by Colonel Granite, who believed she was trying to contact an invasion fleet.
