Space Colony ARK

The space colony ARK is a fictional space colony in the game Sonic Adventure 2.

ARK was designed by Gerald Robotnik and was the first manmade colony in space.

During the events of Project: Shadow, the military invaded the ARK. They were met with opposition in the form of the prototype ultimate life, the Biolizard. The creature was locked away however, and the military arrested Gerald for creating it. They then discovered his granddaughter Maria Robotnik and the true ultimate life. Maria released Shadow the Hedgehog to the earth and was killed.

At the end of Sonic Adventure 2, the activation of the eclipse cannon causes a premade program to enact the ARK's destruction. Somehow, Gerald embedded a program into the ARK so it would collide with earth and kill all those who brought pain to his life. This plan was eventually stopped by the combined efforts of Sonic the Hedgehog, Miles "Tails" Prower, Knuckles the Echidna, Rouge the Bat, Dr. Eggman, and Amy Rose, who eventually convinced Shadow to assist. The Biolizard was awakened and it fused with the colony even after the eclipse cannon was stopped. Sonic and Shadow used the emeralds to becaome their super forms and destroy the Biolizard.

However, earth's gravity continued sucking in the ARK. Sonic and Shadow used Chaos Control to knock the colony away, but in the process, Shadow fell to the earth and was believed dead.
