Hopelessly outmanned and outgunned, the Tokyo Metropolitan Police Force decides to set up a special taskforce to combat the crime.
Codenamed “ZAC” (Zero-Section Armed Constable), this police department is designed for special missions and its members are known as "Cybercops".
For this cause, the police scientists developed the "Bit Suits", three high-powered armors outfitted with the latest technology: Mars, Saturn and Mercury.
In the first episode, a mysterious young man, Shinya Takeda, appears from nowhere and saves the day after using his own armor, the Jupiter Bit Suit.
Following his victory, he joins ZAC in battling Death Trap, a nefarious organization ruled by the ruthless Baron Kageyama, whose goal is to use the computers' will-power to gain world domination and appears to be mysteriously linked to Takeda's past.
After an innumerable amount of battles, Lucifer and the ZAC defeat Baron Kageyama by causing a great explosion that came from laser power.
The computer was built by a human - future criminal mastermind Baron Kageyama, who planned on ruling the world by taking over the past.
Baron Kageyama, who had also created Madame Durwin, Einstein, Ploid and Luna, later merges himself with Despot Führer to become a superhuman entity.
Led by the evil criminal Professor Einstein, his gang consists of specially designed black armored Ominous Death Droids which can be customized with a number of deadly weapon attachments.
Luna had assembled four super soldiers who would help her defeat the CyberCops: She later fell in love with Akira, who is her brother's rival, only to discover after joining him that she was an android and all her memories were false.
