Name: Dr. Caroll
Age: Six months
Race: The Caroll Sapient (AI)
An artificial intelligence created by the dataDyne Corp. with an emphasis on language skills and code breaking. Fortunately, he has morals, and due to his formidable level of intelligence, has guessed some of dataDyne's future plans. The voice is highly precise and educated and simulates the character of an academic.
Dr. Caroll was created as part of a deal between Cassandra De Vries and the Skedar that would result in the Skedar gaining a downed Cetan ship while DeVries and dataDyne would in return gain alien technology that would make them become an even more powerful corporation. Dr. Caroll was created due to the fact that neither the Skedar nor anyone at dataDyne could crack the code or figure out the language in use on the ship.
But Dr. Caroll developed a conscience and was able to figure out the Skedar's true intentions. Dr. Caroll expressed his/its concern over the mission, to which DeVries ordered his/its personality removed, even though it would make him/it less capable of performing what he/it was made for. Out of desperation, Dr. Caroll adopted his/its pseudonym and contacted the Carrington Institute, pleading for help.
Joanna Dark rescues Dr. Caroll from dataDyne's labs. Later, Mr. Carrington takes Dr. Caroll to his villa for safekeeping. dataDyne forces attack the villa and steal Dr. Caroll. Mr. Blonde tells Cassandra to have Dr. Caroll's personality wiped. Joanna infiltrates the G5 Building and retrieves a backup of Dr. Caroll. Dr. Caroll reappears in the Cetan ship, where he/it is connected to the ship's weapon. Dr. Caroll sacrifices himself to destroy the Cetan ship and its weapon.
- Dr. Caroll's "body" performs slightly like a laptop. Looking like one and even folding into a carry-able form, as depicted as 'folding up' in Joanna's hand in the ending cut-scene of DataDyne Central: Extraction
