Alex Elliot is known as the unknown drone "S-D S".
Tessa dug up two drones in the beginning, 001 [Atta (Elliot) ] and 039 [S (in this case, Alex Elliot)]. She made them her "younger siblings" because of how lonely she was in the Elliot Manor.
After Cyn had became a new drone, her and Alex became close friends. Atta was always with Tessa, helping her out around the Manor. When Atta was busy one day, and Cyn had brought Alex in the library basement. After Atta was done with her duties, she couldn't find Alex.
...When she found an oil trail leading to the basement, she saw that Cyn had decapitated Alex. Atta has never been the same after that day. She was later sent to Cabin Fever Labs, used as the first Drone Subject, 001. THE FIRST ABSOLUTE SOLVER HOLDER. (not host because she WAS the Solver, then she was later on nearly killed, giving Cyn the hold of the Absolute Solver, becoming one with it)
After that, Atta was sent to Solver Fever Labs, on another exo-planet called Proxima-1 a more distant JCJ System, then she became the first AS host, not having much control over it.
And now about Alex, a few years later, during Murder Drones S1, he woke up and said to himself "I want to become a Disassembly Drone." And so he did...
He became Serial Designation Syro.
Alex was a new person. Alone.
