Eryk Zang was a convicted serial killer who had murdered nine humans between 2219 and 2226. He was sent to Titan Penal Base but escaped. He pretended to the Robohuman Simon that he was a biomechanics student and agreed to help Simon in his research. However, Simon decapitated Eryk, connecting Eryk's brain to his cognitive processor and using Eryk's face as a mask. (PROSE: Mortal Thoughts)
