"Sonic Adventure 2.5: Omega"
Rotor builds a device to communticate with the Xorda, but Sally uses it and the Xorda won't listen to reason. Dr. Robotnik constructs Giga Bot prime (appearance like Optimus Prime) and only Sonic can power it with his speed. Maximillian Acorn demands that Dr. Robotnik must give him half of his territories in exchange for Sonic's services. Everyone on Mobius, even rivals are willing to work together. Sally joins Sonic to destroy the Xorda with the robot, but after the threat disappears, Dr. Robotnik locks Sonic's feet in so he can never escape. The Xorda launch their ultimate weapon, the Quantum Dial to destroy the world. Meanwhile, Knuckles takes the biggest risk of his life and returns back to Mobius alive, losing his chance to become one with the Chaos force. Giga Bot prime is destroyed when it flies near the Quantum Dial, freeing Sally and Sonic. NICOLE states that if Sonic runs in the opposite direction of the dial, he can destroy it but will implode on impact. Knuckles destroys all of the Quantum Dial's defenses when he returns to life, but can't help Sonic as he has lost his chaos powers. Sonic goes ahead with his plan and disappears as he destroys the Quantum Dial. Knothole residents and Chaotix attend Sonic's funeral not knowing that 849,000 light years away, Sonic has been transported and still breathing...
