This Sim had a major role in some of Lifesimmer's let's plays.
Kayden and his faternal twin sister Kylie spent the majority of their childhood travelling due to military parents. They wanted to settle down in the place they always had dreamed of - Isla Paradiso. When they were finally old enough to be responsible for their own, they moved out into a houseboat.
He got the job as a Lifeguard. He continued his life in Isla Paradiso and met a mermaid named Rosemarie Collins. She gave him some mermadic kelp. Later in the LP he met a woman named Florita Mayor, and she is also a mermaid. They fell in love and they eventually had two children named Eric Mayor and Sebastian Mayor.
- Lifesimmers description of pre-series indicates that Kayden lived in Lunar Lakes, Hidden Springs, France and Setra before she moved to Isla Paradiso with Kylie.
- Identity of his parents is unknown. However, Lifesimmer said that they were both military generals and they traveled all around the world.
