Instead, each episode typically features a different murder case, often involving a unique and compelling killer. There are recurring characters who act as villains in multiple episodes, but they are not the main focus of the series.
Some of the most memorable recurring villains include:
* The Gravedigger: A serial killer who buries his victims in elaborate, ritualistic graves.
* The Puppeteer: A serial killer who manipulates his victims into killing themselves.
* The Gormogon: A serial killer who leaves cryptic messages and riddles for the team to solve.
The focus of the show is primarily on the relationship between Dr. Temperance Brennan and Special Agent Seeley Booth, and the process of solving the mysteries presented in each episode.
