Omega

Omega is the robotic companion of Galactamus, being constructed by him sometime after the end of the War of Deltrax. He accompanied Galactamus on his trip to planet Earth, and helped his creator build a new underground base on the primitive world before placing his master in stasis, promising to wake him up if evil ever threatened planet Earth. He later woke Galactamus up after a revived Darkarayus set his sights on Earth, prompting him to choose five teenagers to become the new Power Rangers Galactic Force.

He later became the assistant to Darkarayus once the latter had a change of heart and succeeded his brother as mentor to the Power Rangers Galactic Force following Galactamus' tragic demise.

He seems to be somewhat of a walking reference to Alpha-5, the robotic companion to Zordon, the original mentor of Power Rangers who began the trend of wise mentors to the teams of Power Rangers to come.
