Main Characters

• Kyle Trager (Matt Dallas) is the protagonist, a teenage boy with no bellybutton and no memory of who he is. His strange case is referred to Nicole Trager, a therapist who takes him home. Kyle must learn to do everyday things like eat and drink, speak, and avoid hurting himself. Season one follows Kyle as he learns about how people live, but nothing of who he is. Season two explains Kyle's existence, and he begins to discover his purpose. Kyle also discovers, in season 2, that he was created by scientists as an experiment. Throughout the show Kyle has encounters with scientific communities that know of his "special abilities" like Zzyzx, MadaCorp, and Latnok. His experiment name is "781227" or "XY". He is romantically interested in Amanda Bloom.
• Nicole Trager (Marguerite MacIntyre) is a psychologist who is assigned Kyle as a patient and decides to take him in as foster child. She is married to Stephen Trager, and has two other children: an older daughter named Lori and a son named Josh. Nicole is Kyle's main source of support and his moral anchor throughout the series.
• Stephen Trager (Bruce Thomas) is Nicole's husband. He is a well-paid software designer who directs a programming team. Stephen and Nicole are happily married and supportive of the kids.
• Lori Trager (April Matson) is the teenage daughter of Stephen and Nicole, as well as the older sister of Josh and Kyle. Lori sneaks out to date Declan and gets drunk at parties. She loves Declan, but they have something of an on and off romance, but in the third season she starts dating her father's TA, Mark. Lori confides in her best friend, Hillary.
• Josh Trager (Jean-Luc Bilodeau) is the son of Nicole and Stephen Trager, and the younger brother of Lori and Kyle. Josh is more interested in pornography than school, and is devoted to "G-Force" online gaming. He introduces Kyle to basketball. Josh struggles during the first season, first with getting admitted to high school then with getting out of remedial classes. Josh is a schemer with a mercenary personality, and is unintentionally predictive about Kyle. His only love throughout the series is Andy Jensen.
• Declan McDonough (Chris Olivero) is a spoiled rich kid and high school basketball star. He is the on and off boyfriend of Lori Trager, yet remains in love with her through the series. Declan's best friend is Charlie Tanner. He also becomes very close friends with Kyle, sharing Kyle's secrets and adventures throughout the series.
• Amanda Bloom (Kirsten Prout) is the girl who lives next door to the Tragers. Kyle is drawn to the sound of her piano and immediately falls in love with her. She also feels an attraction to Kyle, but her mother tries to keep them apart. Kyle is afraid that Amanda will not like him the same if she knows of his origins, though she learns about many of his strange ways and abilities. Their romance continues through the series, even though they break up in season 3, but in the last episode Amanda reveals to Jessi that she will tell Kyle that she wants him back.
• Jessi (Jaimie Alexander) is introduced in the second season, but arrives in the world in the same way as Kyle, but shows a very different personality. About a day after Jessi is "born" she is found by one of MadaCorp's employees, Emily, then they give her a life-full of false memories that include Jessi being Emily's sister. In only small part of the second season does Jessi believe these memories are true, until Kyle reveals the truth about them. As the series progresses, she becomes an increasingly important part of Kyle's story and falls in love with him. Her experiment name is "781228" or "XX"
