Pre-Venjix
Omega 3 was one of several crash-test drones used by Alphabet Soup to test the creations of the facility's charges. Specifically, Omega 3 was assigned to Doctor K. While with her, the lonely Doctor K began to tinker with its program to give it a human-like speech pattern while with her. Omega 3 and Doctor K became good secret friends. According to the agents of Alphabet Soup, Omega 3 was destroyed during a training accident and no wreckage could be recovered. Doctor K was heartbroken, and this led to her trying to keep Gem and Gemma from getting to close.

Return
While battling Colonel Hydromane in the Wastelands, the Rangers encountered a strange sight, a rogue Megazord with parts referencing a dragon and a unicorn. While the Megazord recognized Hydromane as a threat, it also saw the SkyRev Megazord as one as well. Surprisingly, the Zord was an equal match to the SkyRev Megazord. After a short battle (from which Hydromane fled), the Rangers heard the Megazord say "Test complete. Result: Draw. Returning." It then took off. After heard this, Doctor K realized the agents lied to her again, and that Omega 3 still functioned, supposedly protected from the Venjix virus by the Megazord and her own unique firewall codes that were originally meant to keep Venjix contained.
