Peter Parnell is Donna's son, and Ted Forrester's future step-son. He also has a younger sister, Becca, of whom he is very protective. He is close to six feet tall. He has a black belt in judo and is working towards a black belt in another discipline.
When he was eight Peter watched his father being murdered by a werewolf. While his mother cowered, he took the silver-loaded gun and killed the werewolf. He then maintained the adult male role in his family after that, until 'Ted' entered the picture. He was suspicious of Ted in the beginning.
Peter and his sister are kidnapped by Riker in Obsidian Butterfly and he is raped. Anita saved him, while Edward saved Becca. After the ordeal he takes up martial arts and later becomes Edward's apprentice.
Unlike his family he is aware of Ted's true identity and accompanies Edward when he comes to Anita's help in The Harlequin. He is mauled by a weretiger while trying to save Anita’s life. After being hospitalized the doctors offer him a new ‘after attack vaccine’ that would cancel out the lycanthropy if he had caught it, but if he hasn't he’d get the strain in the vaccine, a weretiger. He decides against the vaccine.
In Hit List it is mentioned that he talks to Anita on the phone once or twice a month to discuss his training. He is scheduled to go on his first hunt with Edward in fall of the year he turns eighteen. Anita agrees to accompany them on the hunt.
Edward believes that Peter might have a crush on Anita, because she was the first woman he saw after having his first sexual encounter. He has also been dumped by his first two girlfriends for being too rough.
Age inconsistency Edit
Peter's age is inconsistent in the series. In Obsidian Butterfly, he is 14 years old. The Harlequin takes place seven months later, but he's aged to 16 by then, which is not possible. This is related to a larger timeline inconsistency related to the time that's passed between Obsidian Butterfly and The Harlequin; see the inconsistencies section of the Timeline article for more details.
In Hit List, which takes just under two years after The Harlequin, he is 17, which could work with either his age from Obsidian Butterfly or The Harlequin. It's additionally stated that he'll be eighteen by fall the next year, indicating that he is only recently 17 and will turn 18 next year. In this case, Peter would have turned 16 the year prior, and he should have been 15 in The Harlequin which would make his age consistent with Obsidian Butterfly. This is possibly an attempt to correct the inconsistency with his age in The Harlequin. This would also place his birthday sometime between May and August.
In Affliction, which is nearly exactly three years after The Harlequin, Peter is 18. This is consistent with Obsidian Butterfly and Hit List, leaving his age in The Harlequin as the only inconsistency.
In Crimson Death, Peter is 19, which could work with either his age from Obsidian Butterfly or The Harlequin. If The Harlequin remains the only inconsistency regarding his age, then this would place his birthday sometime between May and July.
