The Ark was completed in 2010, and successfully launched before Cybertron entered the Plait Expanse. However, during its trip to Earth the Ark was boarded by Scourge, who attacked Prime on the bridge, causing the Ark to crash into Arizona Bay. The Nemesis remained for a time in Shattered Glass Earth's orbit, commanded by Megatron. In 2012, General Flagg used GODS system to cripple the Nemesis and knock it out of Earth's orbit, causing it to crash into Mount St. Hilary.
