"Time Shadow," which officially debuted in Episode 19, is an autonomous combat giant robot developed in the 30th century to counter heinous criminals. It usually flies and engages in combat in stealth fighter mode, and in emergencies, it transforms into a giant robot mode to fight criminals. Capable of nimble, ninja-like movements, it fights using specialized super-hard metal weapons called "Shadow Sabers" as dual swords or a bow and arrow. Furthermore, Time Shadow can combine with Time Robo α and Time Robo β respectively to become the more powerful "Time Robo Shadow α" and "Time Robo Shadow β."

"Delta Formation Time Shadow" inherits the transformation and combination mechanisms of the DX toy released at the time, and the main body can be recreated by transforming between "Stealth Jet Mode" and "Robot Mode." By combining the articulated joints throughout the body with the two "Shadow Sabers" made of transparent material, various combat poses can be enjoyed.

Time Shadow further transforms into a reinforced exoskeleton mode and can combine with Time Robo α and Time Robo β respectively to recreate "Time Robo Shadow α" and "Time Robo Shadow β," achieving a more powerful form. Compared to the DX version, movable knee joints have been added to each mode, and pegs to enhance stability have been added to the soles of "Time Robo Shadow β." As accessories, the sword mode and gun mode of the "Pro-Divider," a specialized weapon for the two reinforced forms, are included.
