MURDER! *lightning strike*

Markiplier is dead... What was supposed to be a lively game of poker with close and trusted friends has taken a sinister twist. Someone has murdered Markiplier and now it's up to you to find out whodunit! But be careful... because can you really trust anyone in these blood-stained halls?

Who Killed Markiplier? is a 4-partnote  web series created by Mark Fischbach.

It was first hinted at near the beginning of October, when cryptic images and videos started to appear on his social media pages. The first episode was released on his channel on October 10th of 2017, with the final part being released on Friday, October 13th, 2017. In this series, the viewer is encouraged to play the part of the District Attorney and is privy to a murder mystery surrounding the death of the actor Markiplier.

Since the end of the series, more installments have been made taking place in the same universe, forming an overreaching plot:

  • Interview #69- Benjamin Butler: Roughly a year after the events of the series, Benjamin the Butler answers questions for his interviewer (the viewer of the stream), hoping to appeal to them so he gets hired.
  • DAMIEN: After the events of Who Killed Markiplier, Damien finds himself lost in the woods.

A collection of photos of Abe's office was released after the end of the series that can be viewed here.

TROPES! *lightning strike*

    open/close all folders 

     Tropes present in multiple works 

  • All There in the Manual:
    • The names of all the characters were revealed on Mark's Twitter.
    • A lot of information about Benjamin, as well as info about the history of Who Killed Markiplier? was revealed in his interview livestream here.
    • Mark's "I EXPLAIN EVERYTHING", “Wilford ‘MOTHERLOVING’ Warfstache FULL BREAKDOWN” and "WHY KILLED MARKIPLIER?" streams has him explaining many of the aspects of Who Killed Markiplier?, Wilford ‘MOTHERLOVING’ Warfstache and DAMIEN respectively, answering many questions posed by viewers.
  • Arc Words:
    • "Murder" in Who Killed Markiplier?
    • "It's time to wake up" in DAMIEN.
  • Art Shift:
    • Who Killed Markiplier? is shot in first person perspective like in A Date with Markiplier. Interview 69 is in first person, but in the style of a video conference (which makes sense as it's an interview). From there on the First-person perspective is dropped entirely in favor of using a 3rd person perspective.
    • As confirmed by Markiplier in “Wilford ‘MOTHERLOVING’ Warfstache FULL BREAKDOWN”, where he answers many questions from fans, the change in color when our two protagonists meet in “Wilford ‘MOTHERLOVING’ Warfstache” is to show their conflicting personalities.
    • The style of DAMIEN is animated as opposed to being in live action like the rest of the series.
  • A Day in the Limelight:
    • Benjamin the Butler gets one in his interview livestream where we learn about his history, his relationships with the other Who Killed Markiplier? characters, and his whereabouts after the events of Who Killed Markiplier?
    • “Wilford ‘MOTHERLOVING’ Warfstache” focuses on Abe searching for William after the latter has gone insane and now donned the moniker of Wilford Warfstache
    • DAMIEN focuses on Damien, Celine, and Actor Mark.
  • Ambiguous Time Period:
    • In Wilford ‘MOTHERLOVING’ Warfstache, the setting has a 60s-70s aesthetic, but other than that it's unclear when this story is taking place. This is intentional, as the crux of Abe's realization that the world he's in doesn't make sense is the fact that he has no clue as to how much time he's spent searching for William.
    • Although the description of DAMIEN outright states it takes place after "Who Killed Markipler", it's unknown when exactly it takes place. It's implied through the echoes of "Wilford 'MOTHERLOVING' Warfstache" when Damien is dragged under the ice and the many tree stumps in the ending that its been a very long time, possibly decades.
  • Character Title: Wilford ‘MOTHERLOVING’ Warfstache and DAMIEN
  • Go Mad from the Revelation:
    • In Who Killed Markiplier?, Colonel William goes insane from seeing the District Attorney come back to life. It's what causes him to develop the identity of Wilford Warfstache.
    • Inverted in Wilford ‘MOTHERLOVING’ Warfstache: The reveal is that Abe's not insane; it's the world around him that doesn't make sense. William even says this to Abe.
    Abe: Am I crazy?
    Wilford: No! No-no. No, no, no, no! My friend, you are NOT crazy. Don't let anyone ever tell you that you're crazy.
  • Killed Mid-Sentence:
    • In Chapter 4 of Who Killed Markiplier?, Abe gets shot in the chest by William in the middle of their argument.Don’t worry, he survived.
    • In DAMIEN, Mark gets all of 5 seconds to greet Celine before she embeds her axe in his chest.
  • Large Ham: Colonel William and Abe the Detective.
  • Offscreen Teleportation:
    • Happens in Markiplier Manor. It's subtle at first but becomes overt as the series progresses.
    • William "gains" this ability after the end of Who Killed Markiplier? and does this in Wilford ‘MOTHERLOVING’ Warfstache whenever he is off-camera, which freaks out Abe.
  • Red Oni, Blue Oni: Celine, the red, is temperamental and impulsive, while Damien, the blue, is reasonable and calm. Even their souls after they die in Who Killed Markiplier? appear red and blue, respectively.
  • Shout-Out:
    • There's 2 in Who Killed Markiplier?:
      • Chef's "Little Buddy" has a camera system that is a based off the cameras in Five Nights at Freddy's.
      • Mark (the real one) said in his "I EXPLAIN EVERYTHING" stream that the Upside Down was an homage to Stranger Things.
    • Wilford's story about "the train" in Wilford ‘MOTHERLOVING’ Warfstache is a reference to Murder on the Orient Express.

Who Killed Markiplier



  • Idiot Ball: Once Celine enters the picture and starts informing everyone that something occult is going on, it would make sense for them to get the hell out of dodge. George, Benjamin and Chef leave, but William, Abe, and the District Attourney don't, and they end up suffering for it.
  • Killed Offscreen: We don't actually see Markiplier die.
  • Kill the Cutie: Damien is the nicest character in the entire series, and he dies in the manor in order to advance its plan.
  • Know When to Fold 'Em: At the beginning of episode 4, Chef and Benjamin realize that they will inevitably die if they stay much longer, so they leave as soon as they can.
    Chef: I've spent 25 years cooking for these uppity fucks. I'm not about to die for 'em! I quit! BITCH!
    Benjamin: We need to leave this place. There's only death here now.
  • Kubrick Stare: Darkiplier gives one to the District Attorney at the end of episode 4.
  • Laughing Mad: Colonel William at the end of episode 4.
  • Madness Mantra: The colonel did it the colonel did it the colonel did it the colonel did it the colonel did it the colonel did it the colonel did it
  • Malevolent Architecture: Markiplier Manor is either a sentient case of this or simply just a Haunted House, as noted above in Ambiguous Situation.
  • Manipulative Bastard: Markiplier Manor. Crosses into The Corrupter. Where do you think Darkiplier got it from?
  • Mean Character, Nice Actor: Asshole Mark is played by Mark IRL, who is most certainly not an asshole.
  • Meaningful Name: All the characters, sans Mark, Chef, the District Attorney and the Evil Entity/Markiplier Manor has some form of this.
  • Nice Guy: Damien and Benjamin
  • Not Quite Dead: Abe the Detective after Colonel William shoots him.
  • Offscreen Teleportation: Everyone in the Manor can do it, but the Colonel makes it the most obvious, according to Mark in this livestream.
  • Odd Name Out: Chef's name is Chef, and is the only character whose name is his profession.
  • Origin Story: For Wilford Warfstache and Darkiplier.
  • Plot-Inciting Infidelity: A major factor in starting off the plot is the fact that, years ago, Celine cheated on her husband, Markiplier, with the Colonel.
  • Plot-Triggering Death: Mark's, obviously.
  • Plucky Comic Relief: The Jim Twins.
  • Revenge: The cornerstone of Mark's entire Thanatos Gambit.
  • Room Full of Crazy: The Detective's office is a Downplayed example of this
  • Rule of Empathy: Averted. Damien, the nicest, most sympathetic character dies and his image is used to get the District Attorney to allow Darkiplier to possess the D.A..
  • Rule of Three: Parodied in the first episode:
    Chef: Last night, after I got rid of all of the evidence... of that delicious meal I prepared, and wiped down all the fingerprints... from those filthy dishes, and sopped up all that blood... I retired to my room at 1 am...
    • Played straight with the "life" quotes.
      • Markiplier: Life is for the living
      • Damien: Life is ours to choose
      • Colonel: Life needs a bit of madness
  • Running Gag: Lightning striking whenever somebody says "murder".
  • Sapient House: Markiplier Manor is either a malevolent case of this, or it's simply just a Haunted House. See Ambiguous Situation above.
  • Sealed Evil in a Can: The Evil Entity is bound to Markiplier Manor, and while it is extraordinarily powerful, is limited to the Manor. At least until it absorbs Celine (for her occult knowledge (and power?) and steals the body of the District Attorney.
  • Sensitive Guy and Manly Man: Damien and Colonel, respectively
  • Significant Wardrobe Shift: Colonel William wears an ornate safari outfit and a pair of fancy glasses. Fitting, considering who he was based off of. Once he goes insane and becomes Wilford Warfstache, he dons the iconic outfit he's worn in every other one of his appearances. Mark in the explanation stream explained that the 'pink' of Warfstache is the Colonel's red clothing, faded over (a very long) time.
  • Small Role, Big Impact: Markiplier is only present for episode one and a bit of episode 4, but his death is what causes the rest of the story to happen.
  • Starts with a Suicide: A Suicide by Cop, to be exact. In order to go through with his revenge plan, Mark needs to die, and sets everything up so that the Colonel kills him.
  • Stop Saying That!: Celine orders everyone in episode 3 to stop saying "murder".
    Celine: And don't say that word.
    Chef: What word? Murder?
    Celine: Yes! That word!
    Benjamin: Well, murder is a rather accurate description of what occur—
    Celine: Do you not see the lightning?!
  • Suicide by Cop: In order to go through with his revenge plan, Mark needs to die, and sets everything up so that the Colonel kills him.
  • Tempting Fate: Mark, in episode 1 says "And who knows? I could be dead tomorrow!" Subverted as dying is a core part of his Revenge plot.
  • That Came Out Wrong: Abe has a moment in episode 2.
    Detective: You knew I was onto you and you were trying to whack me off before I could finger you!
    (Abe looks confused for a moment)
    Detective: As the murderer!
  • The Roaring '20s: Who Killed Markiplier? ostensibly takes place in the 1920s. Possibly 1928 as in Benjamin's interview livestream, he states he was born in 1900, and Tyler was 28 in 2017, when Who Killed Markiplier? was filmed.
  • The Smurfette Principle: Celine (and the District attorney depending on the viewer) are the only female characters present.
  • There Is No Kill like Overkill: Mark was stabbed 37 times, poisoned, beaten, strangled, drowned, and shot, in that order. Subverted as it is revealed in a stream that rather than these injuries being the cause of his death, Markiplier committed suicide multiple times in many ways. He was resurrected by the house each time.
    Mark: [The Detective] said "In that order." Not all at the same time. Not even all at the same day. That's just happened to him.
  • Token Good Teammate: Damien, according to Mark IRL, is the only character who had a "human" reaction to Asshole Mark's death.

  • Wham Episode: Episode 4. You go into Abe the Detective's office after the entity guides you there and you see that it's a Room Full of Crazy with evidence incriminating the Colonel and Celine. Colonel walks in and sees this, and is led to believe Abe set everyone up. When he finds Abe, the two have a standoff which results in Colonel shooting Abe and then you. You wake up in the Upside-Down and see the souls of Damien and Celine there with you, saying that they have a plan to get out, unaware that they are being manipulated by The Evil Entity of Markiplier Manor. You agree to the plan and are sent back to the real world. William sees this and comes to the conclusion that death has no meaning, since everyone will come back eventually, and believes that this was all a joke on him set up by Damien and Celine. He goes off to find them and loses his mind, gaining the identity of Wilford Warfstache. Meanwhile, you grab Damien's cane, and your hand transforms into his. You look into the mirror and see a brand new entity: Darkiplier. Darkiplier snaps his neck, gives you a cold Death Glare, and leaves, trapping you in Markiplier Manor for all eternity.
  • Wham Line: "It was all a joke!", courtesy of Colonel William, beginning his descent into insanity and eventual transformation into Wilford Warfstache.
  • Wham Shot: At the end of episode 4, when you look into the mirror and see Darkiplier staring right back at you.

Side Stories

    Wilford 'MOTHERLOVING' Warfstache 

  • Ambiguous Time Period: Abe is straight out of Film Noir, but at one point he uses a vape. Word of God confirms that the setting is supposed to be unclear.
  • Contrasting Sequel Antagonist: In a sense; Whereas Who Killed Markiplier? had a definitive antagonist in the form of The Evil Entity, the closest thing to call an antagonist in this story is Wilford. While both possess supernatural abilities, The Evil Entity had full control over them and used them to consciously hurt others, whereas Wilford has no control over his powers and isn't even aware that what he does is hurting people.
  • Decoy Protagonist: While the video might be titled after our favorite eccentric murderer, it actually focuses on Abe and his realization of the world around him.
  • Earn Your Happy Ending: In the end, Abe finally decides to let go of his grudge with William, deciding to have fun and dance with him at the party.
  • Film Noir: The video uses this style to convey Abe’s perspective. When Wilford shows up, the colors shift from white and black to full color. During a later scene back at Abe’s place, the room is in color, but the colors are all muted.
  • Funny Background Event: When Abe holds Wilford at gunpoint, one of the floor dancers takes longer to notice and upon discovering the scene unfolding, promptly backs away.
  • Identity Amnesia: When Abe confronts him about the events that transpired during "Who Killed Markiplier?", Wilford appears to not understand his questions, only properly remembering when Abe calls him a murderer.
  • Mind Screw: Basically the whole video.
  • Noir Episode: This episode serves as this for the supplementary material. At least in the beginning.
  • Took a Level in Kindness: While at first it appeared he was without remorse, later in the video Wilford admits he is genuinely sorry for what he's done and wants to help Abe when he's not able to make sense of the world around him.
    Abe: Am I crazy?
    Wilford: No! No-no. No, no, no, no! My friend, you are NOT crazy. Don't let anyone ever tell you that you're crazy.
  • Sequel Hook: During his interrogation, Wilford sees something he refers to as "The Train" which he mentions he and Abe took part in. When Abe isn't able to recognize it, Wilford outright tells him it "probably hasn't happened yet".


  • Art Evolution: Since this is an animation rather than live-action, there are noticeable differences compared to the live-action installments, mostly with the character models. For instance, Damien has longer hair and a beard, making him look visibly different from Mark.
  • Berserk Button: It's clear that Celine remains a huge one for Mark.
  • Bittersweet Ending: Mark ends up undoing all of Celine's work to keep Damien safe. As his purgatory breaks down around him, Damien accepts that things will never go back to the way they were before. With that, he offers to take Celine's place so that he can start setting things right and so she can finally get some rest, knowing full well that he'll be irreversibly changed by it.
  • Empathic Environment: The place were Damien and Mark end up reacts to Mark's emotions, becoming more red and glitchy the angrier he is.
  • Evil Plan: While most of the specifics remain unknown, Mark's plan for Damien is to make him the "villain" of the "story" to his "hero".
  • Freeze-Frame Bonus: The Stinger has "Damien's" movements shown in glitchy split second frames before he actually makes them.
  • "Groundhog Day" Loop: Damien is stuck in a loop of collecting wood, going home to Celine, watching Celine leave, and going to sleep.
  • Laser-Guided Amnesia: Damien has forgotten the events of "Who Killed Markiplier", being unable to recognize Mark for a few seconds when he finally sees him again. It's only toward the end where he begins to remember everything.
  • Never My Fault: Mark refuses to believe that Celine ran away because of him and thinks that everyone is ungrateful for his "gifts".
  • Nice Job Breaking It, Hero: Per Word of God, Wilford Warfstache's influence, represented by the pink flower, has begun breaking down the purgatory Damien resides in. While this allows Damien to remember everything, it also has the consequence of allowing Mark to manipulate it and bring Damien to him.
  • The Stinger: The end credits abruptly glitches back to the now-destroyed cabin. "Damien" is then seen slowly emerging from the cabin, the video and audio heavily glitching as he does. The final shot is Damien's face close up, heavily resembling Darkiplier.
  • What the Hell, Hero?: Damien calls out Mark for setting up the events of "Who Killed Markiplier" and betraying all of his friends.
    Damien: You took our lives! You betrayed me! You betrayed William! You even betrayed Celine!
  • Wrong Genre Savvy: Its clear that by the time of the story, Mark has become deluded into thinking that he is the "hero" of the story and that Damien will make a great "villain" for him. Word of God states that he is unable to process that he is in the wrong and that this isn't something Damien wants.
  • You're Insane!: Damien realizes just how crazy Mark has become when he starts talking about his "story" and tells him to his face that he is out of his mind.
