Z

A petroleum like abyss creature that took Prime Dottore's form after beeing accidently brought to the lab. Instead of agressive, it became curious with the segments and all the knowledge and experiments, deciding to slowly infiltrate itself between them. At first, the others were confused, but they just accepted him as new segment, not knowing what it truly was.

Eventually he was discovered, thus making an agreement with prime to remain and continue the work. A few tries there and there, and it was able to "hack" into the segment system, finally able to hear everyone's thoughts.

He was named Z, but also received the nickname crow due to his fondness for the black birds and feathers. His beaky"mask" is actually his actual face.
