Deca is one of the early Alpha Series Big Daddies given the task of protecting Abigail Winston.


Deca was one of the few female Alpha Series made into a Protector, however, this was mainly by mistake however, considering the fact that she was framed and was forced into Persephone. Originally, she would have never been made into a Protector, but she knew the only way to get out of Persephone was by becoming a Big Daddy. So, with help from a close friend on the inside, she was turned into one of the few female Alpha Series. Using metal bands to suppress her large breasts and extra padding for her lack of muscle mass (She was spliced to the normal standards for an Alpha Series, however, this still showed her feminine physique to a certain degree, thus needing the extra padding.) After she was released from Persephone, she was put into the Protector Program to start her training, proving to be far more intelligent than the other protectors. She was proven to use environmental hazards and complex strategies for fighting foes, including using the Plasmid Hypnotize to send a Rumbler Big Daddy after a Big Sister, using an oil canister with loads of Proximity Mines and even Trap Rivets attached to it to destroy them both after the fight, throwing it with Telekinesis. After finishing her trials, she was paired with Abigail Winston, one of the Little Sisters.
