Bruce Wayne, John Connor and Other Characters With Mommy Issues (Video)

'Game of Thrones,' 'Dexter,' and 'The Flash' also feature moms who make unusuallly large marks on their kids.

Absent or overbearing mothers are a common trope in fiction, but some characters take that to a whole new level. Their mothers become integral in lifelong obsessions in crime fighting, serial killing or saving humanity.

Below are five of the prime examples, in honor of Mother's Day.

Bruce Wayne/Batman

No one has taken the loss of his parents to more extremes than Bruce Wayne, who wages a one-man war on crime in Gotham. Thomas and Martha Wayne were gunned down in front of Bruce, who goes on to become The Batman. While Thomas gets much of the screen time in Christopher Nolan's Dark Knight trilogy, Bruce is equally disturbed by the loss of his mother, whose pearl necklace plays a memorable role in The Dark Knight Rises after Selina Kyle (Anne Hathaway) takes it.

John Connor (Terminator franchise)

John Connor was raised from birth to be the savior of humanity, with his mother Sarah training him to lead a rebellion against the killer artificial intelligence Skynet. While Terminator 2: Judgment Day to date has been the only film released in which John (Edward Furlong) and Sarah (Linda Hamilton) have starred in adventure together, this summer's Terminator Genisys will feature Sarah (this time played by Emilia Clarke) and John (Jason Clarke) at odds with each other. (More on that here.)

Barry Allen/The Flash

Barry Allen's (Grant Gustin) mother was murdered by the Reverse-Flash when he was a boy. His father Henry (John Wesley Shipp) was wrongly convicted in the murder. Fifteen years later, an accident gives Barry incredible speed powers, turning him into The Flash. He becomes obsessed with the idea of using his speed to travel back in time and prevent his mother's murder, a theme that dominates the first season of The CW superhero drama.

The Dragons (Game of Thrones)

Daenerys is Mother of Dragons, raising Drogon, Viserion and Rhaegal into healthy (and sometimes murderous) creatures. They helped her claim an army of her own. And while she can't necessarily tame them, they ultimately exist for her to use to reclaim the Iron Throne in Westeros. At least, that is her hope.

Dexter Morgan (Dexter)

Dexter (Michael C. Hall) traces his Dark Passenger (his urge to kill) back to witnessing his mother's murder as a small child. Though his adoptive father Harry (James Remar) provided him with a code to dictate whom he would kill (only other killers), Dexter's mother is the catalyst for his entire life's work.
