24 years after the events of Dispatch a new Mecha hero has emerged known as Mecha Gal, who had made her debut as a hero after the previous Mecha Man who had been dubbed Mecha Man Specter abandoned his moral code of being a true hero.
These two individuals real identities are Chase Robertson and Robin Robertson. The 22-year-old son and 18-year-old daughter of Robert Robertson the Third and Courtney Robertson, also once known as Mecha Man Blue and Invisigal.
While their father is widely considered to be the greatest Mecha Man of them all, Chase is considered a disgrace by the public after he had murdered Shroud with the whole world watching and went rogue as a vigilante afterwards. Robin didn't even want to be a hero to begin with but she knew that someone had to keep the family business going after her brother went a-wall.
But one fateful day Chase is sent back in time to shortly after their father had defeated Shroud, and he's not the only one who was sent to that time period.
The first two Mecha Men - Robert "Bobbie" Robertson the First and Robert "Robbie" Robertson the Second - have both been sent forward in time from the days they had died, shortly before they were killed.
Now all in the same time period, the four Mecha Men along with Z-Team must join forces if they're to fix the timeline before a paradox happens that destroys the universe.
