Transformers: Cybertron
An older adult version of Rad also makes an appearance in the final episode of North America's Transformers: Cybertron alongside Carlos and Alexis, waving goodbye to the Autobots as they leave to set up a Space Bridge. They are also seen in the end credits of the final episode being photographed at Coby and Lori's wedding. These scenes are not part of the same episode of Transformers: Galaxy Force, as Galaxy Force was not intended to be a continuation of the Armada/Energon story, while all three are parts of the Unicron Trilogy in America.
