- Ascended Fanon: Darkiplier started out as a fan concept back in 2012, which Mark would allude to from time to time without fully confirming the character's existence. That changed in A Date With Markiplier, when Darkiplier was finally made into a full-fledged character.
- Breakthrough Hit:
- While Mark was already a rising star on Youtube by August 2014 (with nearly 3 million subscribers accumulated over the course of two years), the release and subsequent craze of Five Nights at Freddy's drew many more people to his channel for his playthrough, as he was among the first Let's Players to complete a full run. In less than a year since his first FNAF video, his subscriber count had passed 8 million and Mark became an even more prominent figure in the Youtuber community. He also became inexorably linked with FNAF, playing the sequels and several fan games, plus creating a few original sketches and songs based on the franchise.
- Another example would be Slender. Mark had about 2,000 subscribers when he uploaded his first video of it in July of 2012. By September, his subscriber count had grown to 10,000 and it ballooned to nearly 50,000 by the end of the year. His videos of Slender and its many craze-spawned fangames, along with the horror reaction compilation of those games, were the most popular of his early videos and were what bought his channel a lot of initial attention.
- Creator's Pest: Based on what he said during his February 2017 charity livestream, Mark avoided using Darkiplier in his videos because of the way Dark was being romanticized by the fans. However, when making "A Date With Markiplier", he decided to bring Dark back to his horror roots and take the character seriously.Mark: ...over time Darkiplier became less and less about the scary figure and more about this romantic figure, and it always rubbed me the wrong way. And I kind of shied away from Darkiplier for a while. And I really really really- if I was going to bring Darkiplier, and when we thought about this, we thought, okay there should be a Darkiplier route. And that was there from the beginning, and so when I wanted to do it I wanted to do it my way, and I wanted to do it right, and I wanted to have this unending level of creepiness.
- Colbert Bump:
- Mark's brother is the writer for the webcomic Twokinds, and has appeared in several of his videos. As you can probably imagine, considering Mark's popularity, that helps a lot when it comes to getting a larger fanbase.
- While Cyndago was already a popular channel before Mark's involvement, his interaction with Daniel and Ryan helped boost the channel's popularity.
- The Garden Scene from Nanalan has more than doubled in popularity after he watched it in his "Who's Markiplier's Girlfriend?" video.
- Shirk's "Haunted"(Mark's outro theme for horror games) has gotten a boost in popularity ever since he started using it.
- He Also Did: Though mostly known for his Let's Plays and internet videos, he's also the voice of 5.0.5 in both the English and Spanish versions of Villainous.
- Hostile Show Takeover: On January 12, 2016, Markiplier's channel was hijacked as a result of the XSplit password leak that had previously led to Vinesauce Joel's channel being taken over in November of 2015. Unlike with Joel's case, Mark's hijacker did not address his viewers, only displaying their logo and Twitter handle with music playing in the background. Furthermore, while Joel's hijacking occurred on a Saturday and thus dragged on for almost a week due to Google's employees not working on weekends, Mark's takeover occurred on a Tuesday, meaning that Google was able to respond almost immediately and purged the hijacker from Mark's channel in only five hours.
- Meme Acknowledgement: Mark is aware of him looking like Maes Hughes from Fullmetal Alchemist. Guess what happens when he styles his hair similar to Hughes?
- Playing Against Type: His usually humorous persona is nowhere to be found in a dramatic reading of The Scarecrow Corpse.
- Promoted Fanboy: Remember that fan who did a backflip for Mark at Pax East 2015? That's Ethan Nestor (AKA CrankGameplays), Mark's current video editor and good friend.
- Referenced by...: "Markiepoo", a memetic nickname associated with Mark, is one of the officially recognized player character names in Fallout 4 (meaning certain characters have it programmed into their voice acting).
- Series Hiatus: Although Mark takes pride in not taking breaks, he has had a few:
- He quite understandably took some time off after Daniel's death.
- In late 2017, he went away for a month to both spend time with Amy and because he felt his latest videos weren't up to his own standards.
- June 24th, 2018 had him take a few days off to process the death of his niece, who was killed in a car accident.
- Streisand Effect: Parodied. His Penis Cloner video has a thumbnail of him with a repulsed look with the caption "DON'T CLICK". As you can imagine, all his subscribers and many, many other people clicked on it.
- What Could Have Been:
- Mark revealed in his Undertale livestream that he made five episodes of the game during his initial run, but didn't release the next three episodes due to being discouraged.
- Team Four Star has approached Mark to play a role in Dragon Ball Z Abridged several times, with Broly being their top choice for him, but Mark's work schedule has always been far too busy to allow it.
- Why Fandom Can't Have Nice Things: Mark's first playthrough of Undertale is a huge example of this. After his first two videos, Mark was hit with a very vocal section of the Undertale fanbase heavily criticizing him on his voices for the charactersnote to the point they rudely demanded he change them to what the fandom more readily accepted as their head canon, not to mention aggressively spoiling the game's plot and attempting to push a specific playstyle on him, proclaiming that he "wasn't playing the game right". As a result of this, Mark decided to abandon the series with no intention of ever returning to the project, making his aversion to Undertale somewhat of a Running Gag. After awhile, Mark decided to give the series a second chance, but did so on livestream with Tyler, stating outright he was ignoring people's spoilers or criticisms and that he would play the game his own way.
- The Wiki Rule: Has one as of early 2013. And it comes in really handy, too, especially considering that it does an in-depth listing of all the games he's played, even the ones that don't have a page in this wiki. In fact, if you do actually want to make a page here about any of those games, we do recommend you check out his wiki first, you can find some really useful information there.
- Written-In Infirmity: "Try Not To Laugh Challenge #19" was done two days after Mark had his wisdom teeth pulled.
