S3·E51 Towards a New Future

Bass reappears and now infused with the power of Nebula Grey, he deletes Slur. Meanwhile, Dr. Regal gains access to Duo's power and begins his attack on Earth, but Duo kills him before beginning the erasure of Earth. The CrossFusion Members travel to Duo's comet, avoiding demise as the Earth vanishes. They confront Duo, begging him to reverse the erasure, but Duo cannot comprehend their pleas, having more interest in CrossFusion instead, a technology similar to his own race's.
