Notacon was frozen in the year 3000 for stealing some vegetables because no one would feed him due to his appearance. He was thawed 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.
Notacon managed to get away from the criminals and hide in the city 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 violent 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.
Frax was soon able to take control of Notacon's body through the device attached to his head hours earlier, and force him to fight and grow to giant size. While the Shadow Force Megazord Mode Red takes him on and tries to hold him in place, 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 freeze him with the Blizzard Slash, much to his delight as Notacon desired just that from the start. Trip promised to help Notacon someday in the future, and the Rangers bid Notacon sweet dreams.
