The apparently very convincing android assistants of Dr. Droid. The original Drena pretends to be Phil's girlfriend in order to gain unrestricted access to the Pond and Drake One, stealing the main processing chip for Droid to use in his own HAL-like super computer, J76412. Later it's revealed that there are at least two Drenas working for Dr. Droid, a pair which a lovesick Phil refers to as his "double dreamboat" just as the Ducks dispatch them both.
