[4] His lifestyle consists of living in a two-story beachfront home, drinking excessively, smoking cigars, taking drugs, constant womanizing, gambling, and usually wearing bowling shirts and shorts.

He has a vast range of phobias, including stage fright (unless he is drunk), commitment, his mother, spiders, large birds, germs, change and hard work.

Following Sheen's dismissal from the series in March 2011, the character was written off in the ninth season, with his wife Rose implying he was killed by a train in Paris while on vacation.

[5] Charlie's ghost, portrayed by Kathy Bates, returns as a hallucination to Alan, revealing that he is living in Hell trapped in a woman's body.

However, in the series finale, "Of Course He's Dead," Rose reveals that Charlie had been alive all along (albeit brainwashed) and she was keeping prisoner in the basement of a house that she purchased in Sherman Oaks after returning to the United States.

Charlie drank a lot when he was a teenager, was a chain smoker, and constantly ran away, nevertheless his mother did not mind because he always came back, and generally did not care about her sons.

[7] Charlie constantly criticizes Alan and Jake's presence in his house, but generally seems happy that they are around, because they are the only people who have known him for a long time and accept his unconventional life.

In "I Can't Afford Hyenas," Charlie is shown to have no understanding of how to care for his own living expenses because he entrusts an accountant with managing his cash flow and paying the bills.

Charlie becomes aware of his financial problems after he receives notices from the bank that his accounts are delinquent, his credit cards are maxed out and his car is in danger of being repossessed.

[9] In the final few months of his life after Chelsea left him, he reverts to his old ways: drinking heavily, gambling, smoking marijuana to help him sleep and partying hard for hours.

This began to affect him psychologically and physically; he aged considerably, gave himself a bad haircut, broke several toes and received a black eye from one of his trips to Las Vegas.

It is revealed that Charlie had postulated about the various causes of his death, including liver failure and being pushed in front of a bus, and that he questioned his condescending behavior towards women.

While Alan is hospitalized for a mild heart attack, he awakens to find a strange woman sitting at the foot of his bed, dressed like Charlie and smoking a cigar.

Charlie proceeds to explain that he ended up in Hell, and, as part of his punishment, must live eternity in the body of a large, older woman, albeit with a pair of testicles (he does not consider his new form all bad, as he is able to grope his own breasts).

According to Chuck Lorre, the show's producers were so impressed with Bates performance, that they were considering bringing her back in the recurring role of "Alan's demonic spirit guide".

Berta mentions him in "I Scream When I Pee", when saying that she did not think she could work for anyone besides Charlie, but says that Walden is the greatest boss she ever had, after he comes to cheer her up on her birthday and buys her a car.

Later at Pavlov's, Jenny, Walden, Alan and Evelyn toast to Charlie as a father, brother, son and guy who bought his beach house after he was hit by a train.

Walden talks to Charlie's ashes for the first time in season 11, asking him for a sign of advice on what to do about his love life and thanks him for the house, stating, "you'd have to be on crack to give all this up".

He escapes after four years, collects $2.5 million in royalty money, and sends messages to Alan, Evelyn, and Walden, warning of his imminent return and threatening revenge against them.

Instead, Sheen's likeness is depicted via animation as a re-enactment of events when Rose is explaining what happened in Paris and by a stand-in in the last scene which only shows Charlie from behind.

According to showrunner Chuck Lorre, writing in the vanity card that appeared at the end of the episode, Sheen was offered a role in the finale where he would have "walked to the front door in the last scene, ring the doorbell, then turn, look directly into the camera and go off on a maniacal rant about the dangers of drug abuse.

Instead, he wanted us to write a heart warming scene that would set up his return to primetime TV in a new sitcom called The Harpers starring him and Jon Cryer.

He is an alcoholic womanizer who has engaged in decades of frequent one-night stands, prostitutes, casual sex, and short-term relationships, in stark contrast to his brother Alan's inability to garner much female attention.

After running into each other four years later (see "A Jock Strap in Hell"), Charlie feels guilty about this and hires her as Jake's private tutor, leading them to resume their romantic relationship.

Charlie also fell for his future stepsister, "Courtney" (Jenny McCarthy) in Season 5, and after agreeing to stop seeing her due to their relationship to each other, he lends her a substantial amount of money and proposes moments before they become step-siblings.

Near the end of season 5, Charlie met an older woman (Susan Blakely) named Angie who was also the author of a relationship self-help book that he was interested in reading.

Charlie then made matters worse by vomiting on a baby in public while apologizing to her, and subsequently slept with Chelsea's best friend, Gail (Tricia Helfer).

Panicked over the impending end of his bachelor lifestyle, Charlie finds himself blacked out drunk in bed with Betsy and Alan shortly after their meeting in Pavlov's Bar.

To help wipe the disturbing memories from Charlie's mind, Evelyn told him of the time she cheated on her third husband with circus folk, including a clown, strongman, bearded lady, acrobats, and dwarfs, in one debased night.

After Alan telling him that he's probably gonna be dead for ten years by the time she turns 70 (which ironically came true, as he died not too long after), he went to Michelle and told her that he was interested in being in a relationship with her.
