The aliens from Abducted are the main antagonists of said episode. They appear as green humanoids with semi-circular noses, black eyes, and insect antennas. Their mouths are only shown when the aliens are looking up, screaming, grinning, or performing an action that involves opening the mouth so wide that you can look down their throat.
Their ship appears to resemble a typical cartoon UFO, colored grey with yellow windows. Monica and Jimmy Five are abducted onto this ship.
The aliens's leader is a vindictive being. He wears a golden crown on his head to signify his position. He is the only one whose sex has been confirmed. The guards, who wield electro-staffs, may be male or female.
These aliens and the one from And so, Thirty Years have Passed, are not to be confused with each other, as the latter was kinder.
