Dennis Reynolds

Dennis was born August 17, 1976, alongside his twin sister Dee. He was raised by his mother Barbara and father Frank. In the Season 2 finale, "Dennis and Dee Get a New Dad", Dennis and Dee find out from their mother that they are the children of Bruce Mathis, a wealthy, kind-hearted philanthropist whom Barbara had an affair with. Dennis was beloved by his mother, who left him with her mansion after her death (on the condition that Frank would not be allowed to enter the property). He considered himself to be popular in high school, although it was later revealed that he was never that popular and that his prom date slept with Mac. Dennis graduated from the University of Pennsylvania with a minor in psychology and was a member of the Delta Omega Lambada fraternity.

Dennis is easily the most psychopathic member of the gang, having displayed signs of narcissistic and Borderline personality disorder. The latter of which he was diagnosed and prescribed medicine with in the Season 10 episode "Psycho Pete Returns". Over the course of the series, Dennis's mental condition has significantly worsened, resulting in him becoming more delusional and deranged, even referring to himself as "The Golden God" on numerous occasions.[1] Dennis also has an extremely fragile ego, as revealed through his upset reactions to being rejected by his peers at his high school union and receiving a one-star (and eventual zero stars) rating on a dating website.

It has been suggested numerous time that Dennis is a serial killer, as shown when it is revealed he keeps zip ties, duct tapes and gloves in his car and when he threatened to turn Dee's skin into a lampshade or a piece of high-end luggage.[2] When asked about the possibility of directly confronting the question of Dennis being a serial killer in an interview with Rolling Stone, series creator Rob McElhenney claimed that they are "about close to (the question) it as possible", and the audience will go along as the series goes on.[3]

Dennis is a fan of Bryan Adams and Rick Astley, and drives a 1993 Range Rover County. The car was blown up with a bazooka after Dennis leaves for North Dakota in the Season 12 finale. He would purchase a near-identical Range Rover in the Season 13 episode "The Gang Gets New Wheels".

Dennis has shown to be predatory towards women. He lost his virginity at age 14 when he had sex with his school librarian Ms. Klinsky, although he is in denial that this is in fact rape. He keeps a camcorder in his bedroom, which he uses to record every woman he had sex with and keeps and rates each tape. He has a self-designed "D.E.N.N.I.S System", where he gaslights and emotionally abuses women in order to have sex with them before abandoning them. It has been implied that Dennis is a serial rapist, as he has claimed that the words "no", "stop" and "don't" never stops him from going ahead with his advances (something Mac later confirms in "How Mac Got Fat" when he tells a priest that Dennis often advises him to "never let someone's resistance stop you from getting what you want") and that a woman on a boat with him in the middle of the ocean won't turn down sex because of "the implication". He revealed in the Season 13 episode "Time's Up for The Gang" that he has received text messages giving consent from every woman he had sex with, although he implies that he may have sent them himself. It was revealed in the Season 8 finale "Reynolds v. Reynolds: The Cereal Defense" that Dennis has numerous bench warrants of sexual misconduct against him in court.

Dennis has known Mac and Charlie since childhood and is roommates with Mac. They shared an apartment together until it was burned down in the Season 9 finale "The Gang Squashes Their Beefs". They then moved into Dee's apartment and had to share a bed with an old man as a part of a bet with Frank ("Mac and Dennis Move to the Suburbs"). Their old apartment was rebuilt in Season 12, and both Mac and Dennis moved back by Season 13. Dennis often partners up with Mac for numerous schemes, including the aliases "Honey and Vinegar" as well as selling merchandise for Paddy's Pub together. They also heavily rely on each other in their personal lives, one instance being Dennis having Mac skin an apple before eating it ("Mac and Dennis Break Up"). Despite their friendship, Dennis is often annoyed at Mac, mostly for his apparent attraction to him.

Dennis views Dee as inferior to him and is controlling for her. Often joining the remainder of the gang in mocking and despising Dee. Despite their sibling rivalry, Dennis and Dee often team up together, especially in the game of Chardee MacDennis, where Dennis and Dee perform exceptionally against Mac, Charlie, and Frank. There are also instances where Dennis looks out for Dee, such as when he showed care for her when she gives birth and when he became concerned that she will fail miserably when her stand-up career began to apparently take off.

Like his sister, Dennis despises Frank as a father. And at the start of the series was reluctant to let Frank join 'The Gang'. After it was revealed that Frank is not their biological father, both Dennis and Dee stopped treating him like a father merely as a member of the gang. Their relationship remained relatively hostile in the earlier seasons of the series, with Frank at one point selling Dennis out to prostitution in order to pay off $25,000 owned to the mafia ("The Gang Gets Whacked"). Over time, however, Dennis begins to partner with Frank more often, including helping him cook up Paddy's books through several money laundering outlets ("Sweet Dee Gets Audited") and teaming up together to buy out a ski resort ("The Gang Hits the Slopes").

In the Season 6 premiere "Mac Fights Gay Marriage", Dennis marries Maureen Ponderosa, his high school sweetheart. After falling out with her, Dennis attempts to divorce Maureen, but she hires The Lawyer to negotiate with Jack Kelly, Dennis's lawyer. They reached a settlement where Maureen agrees divorces Dennis on the grounds that he pays for her alimony and $90,000 debt, much to Dennis's displeasure. In Season 8, Dennis attempts to have Maureen sign off their alimony agreement as she prepares to marry Liam McPoyle, but Dennis has sex with her upon seeing her breast implants. The wedding would later be called off when chaos breaks out after Maureen's brother Bill spiked the wedding milk bowl. Over time, Maureen begins to transform herself into a cat through plastic surgery as well as cat-like behavior, naming herself 'Bistet'. She dies in season 12 after attempting to climb the roof of a building and falling off, though it is implied that Dennis might have pushed her ("Making Dennis Reynolds a Murderer", "Paddy's Has a Jumper").

In the Season 12 finale "Dennis' Double Life", Dennis reveals that he has fathered a child in North Dakota after a layover there ("The Gang Beats Boggs"). He attempts to fake his own death to avoid caring for the child, but later decides to move to North Dakota to raise him.[4] He would return to Philadelphia in the premiere of Season 13.
