I've noticed there is a pole asking about his appearances, or lack thereof. It did get me wondering: The E-Series ran off of animal power, correct? So.... How did Omega even restart after waiting all those years? Surely the little critter would be dead by then.
Did they stick another poor, helpless creature inside him? And doesn't the animal, as seen in Gamma, have influence as to whether they obtain free will? Wouldn't changing said animal have a drastic affect on the robots personality?
