Born as the son of a kittypet, Cykes originally lived a luxurious life. However, when his siblings fell ill, he was placed in a box and dropped in the middle of the street, abandoned. One by one, the other kits slowly passed away. Cykes managed not to get sick, and often left the box to find food. He was devastated by his siblings' deaths, but he soon pushed them out of his mind.
A two-leg decided to adopt him one day, taking him home and looking after him kindly.
It was a nice couple of years, but Cykes grew bored. After watching the clan cats run around outside his backyard, he decided to run away from his home. Mere days later, he found himself caught in the middle of a clan fight. Though scared and frightened, he found that he enjoyed the thrill of the excitement.
When he finally got away, he decided he would cause as much trouble around the clans as he could. It made him feel alive, and helped him forget about his past.
