In between the occurrences of Cybertron and Transformers Energon animated series, Wing Saber experienced an issue with authority. This led to a disagreement with Optimus Prime over the life of a human astronaut. Despite this dispute, he departed from his duty as an Autobot and left. Later, he reconnected with the Autobots on Earth during a battle against Starscream. Following this encounter, Wing Saber regained his ability to merge with Optimus Prime and became a valuable member of their team once again. In the end, he engaged in combat with Starscream.
Wing Saber transforms into an A-10 Thunderbolt II jet. He is equipped with two Flap Swords and can activate the energy cannon on his back using his Cyber Key Power (Galaxy Caliber). When combined with Optimus Prime, he enters Sonic Wing Mode (Sonic Convoy, featuring the special attack Sonic Double Impact through the Force Chip).
