Introduced in Plague, Darla was an eight-year-old child living at the Project Cassandra Research Building. She lived across the hall from Toto the Truthteller and loved Hello Kitty. It is known that she was a freak, but her power levels were unknown. Her power was the ability to walk through walls. She attempted to escape the facility by phasing out of it, she failed when one of the guards tasered her while she was just halfway through, killing her by slicing her in half. Computer Jack notes the similarity between her power and the teleporting cat that Albert Hillsborough discovered while listening to Toto.
