Abigail
Sweet, pretty and somewhat naive at the start of the novel, but easily swayed by the influences of others. Abigail cares a bit too much about what other people think of her and is very prone to peer pressure. She has very little personality of her own.- The Ditz: She's not particularly antagonistic, but hanging around Blossom and Oliver too much begins to colour the way she acts.
Blossom
A chubby girl who had come from a wealthy family before being orphaned shortly before the events of the novel.- The Sociopath: Everything is about her needs alone, and she sees others as either obstacles or tools, frequently using people for her own gain and being able to switch emotions whenever she needs to.
Lola
A juvenile delinquent with a strong sense of right and wrong.
Oliver
Athletic, handsome and self-confident to the point of arrogance. He and Blossom provide the main driving force of the cruel actions called for by the machine.
- Toxic Friend Influence: He, more than anyone else, wants the others to come over to the dark side.
- Urine Trouble: One of the things he does to appease the machine is to stand on an upper landing and take a leak on Blossom and Abigail.
Peter
A boy who's described as being somewhat slow and meek. He generally obeys the most authoritative person in his vicinity, which in this situation, should be Oliver.- The Power of Friendship: Lola gives him a measure of protection against Oliver.
