Felix is the youngest child of the Vlcek family, making him Rodney's youngest brother.

Felix's life has yet to begin, but much like a lot of 10-year-olds, he's a playful, curious and excitable boy. His exposure to werewolves started when his home was almost invaded when Jared was visiting his friend Rodney, but Jared's stalker followed him, putting the family's life in danger. He then witnessed Rodney's development as his brother tried to overcome the urges and instincts of his werewolf form in the early stages of his werewolfism. But witnessing his brother's fate made Felix love him more and he grew an appreciation for werewolves as a whole and has been curious about the history of the curse ever since.

He has been bullied at school ever since his peers found out that his brother is a werewolf. Emotionally, it has hurt him quite a bit, but having Rodney nearby has helped him greatly on top of the support he receives from his family. He's continued to pursue his hobby, perhaps inspiring him to get a job in a related field when he grows up.
