Like all other mutants, Notacon was created as the result of the chemical accident. He is a peaceful but powerful mutant. Notacon was frozen in the year 3000 for the crime of petty theft. He only stole some vegetables because no one would feed him due to looking threatening, much to his sadness. He was released in the year 2001 by Frax for Ransik, who upon learning of the mutant's minor crimes and lack of aggression told him he would fight whether he liked it or not. Frax placed control device on his back, but Notacon escaped.
Notacon managed to get away from the criminals and hide in the city (though many people run away from him because of his appearance) where he was discovered by Time Force as Ransik's forces were searching for him, having read up on his record and negligible crime they promised they would help him.
Unfortunately the same courtesy was not extended to Eric who believed that all mutants were evil based solely on not being human and should be killed outright, if not for Trip standing between Notacon and Eric and revealing his own status as a non-human the Quantum Ranger would have destroyed him. Eric eventually showed mercy for Notacon and spared him. But he didn't tell it to Trip. He said that "It is something wrong with pistol".
Frax was soon able to take control of Notacon's body and force him to fight and grow to giant size by removing the seal patch that's located on his upper left leg. While the Shadow Force Megazord Mode Red takes him on and tries to hold him in place, but Notacon is too strong. To the Rangers' shock, Eric uses the Q-Rex to hold Notacon in place so Trip can destroy the control device with the Electro Booster. The Rangers then freezed Notacon with Blizzard Slash much to his delight as Notacon desired just that.
Trip promised to help Notacon someday in the future, and the Rangers bid Notacon sweet dreams.
