Goof: In the first scene inside the Sentinels' ship after Astraea is abducted, Sentinel One is seen mouthing the words while Hercules' voice says "Then it was magnetic energy that pulled Astraea into that ship."
This is the first episode to mention that the Sentinels have rocket belts rather than the power of flight. This bears a strong resemblance to DC Comics' Legion Of Superheroes series at that time in which all non-flying members were issued a ring worn on finger that gave them power of flight.
Goof: Inside the mountain base, there are four robots operating, while only three took part in the heist and later exit the base.
Goof: When the Sentinels complete their mission, Astrea reassures MO that they're back, but MO's eyes are flashing during those words as if he was speaking them.
