Nylon was a cyborg who was a close friend of Silas. He is killed by Ender, because Ender thinks that Tread is the betrayal who is killing everyone. He is wrong, and they find out that it was actually Endin, possessed. He has blonde hair and is popular with the ladies. Nylon is a cyborg because he was once an astronaut, and aliens ate all of his crew and attempted to eat him, but he was saved by Cilan and Silas, who took him back to base for treatment.
