When Optimus Prime went into Unicron on his own, he was interrupted by Starscream, Mirage and Shockblast. When Starscream was about to attack him with his sword, Wing Saber bashed through the wall and blocked the attack. Optimus, who thought, that Wing Dagger died, was happy to see him. After Wing Saber explains how he survived, he separated into four parts and combined with Optimus into the flight mode. The golden glowing Optimus bashed the Decepticons out of his way with a single blast and headed out to battle Megatron.
- Optimus uses it most of the time, even after they could combine into the more powerful Fight Mode.
