(WAPOOSH) Top of the mornin' to ya, laddies! My name is Jacksepticeye, and welcome (back) to [game name]!

―Jacksepticeye’s classic intro

Hello all you beautiful people out there, my name is Jacksepticeye, and...

―Jacksepticeye's old intro

Seán "Jack" William McLoughlin (born: February 7, 1990 (1990-02-07) [age 34]), better known online as jacksepticeye is an Irish YouTuber, video game commentator, occasional vlogger, voice actor, and founder of the clothes company CLOAK along with Markiplier, as well as the coffee company Top of the Mornin. He is known for his energy, distinct accent, loud commentary and sometimes gentle nature and (currently old) signature green hair (which he dyed for charity alongside Markiplier). His channel is the 130th most subscribed channel on YouTube, and also the most subscribed channel in Ireland.[1]

In a video released on July 2, 2020, Seán went on a month-long break due to mental health and the situations going on currently with YouTube and Twitch while explaining why he doesn't want to upload daily content because he needs to, he is taking a month off because he doesn't want to make YouTube videos at this time.[2] Seán returned to his YouTube channel on August 11, 2020 with a livestream announcing his return to uploading content following his break.

Personal life


The nickname “Jack” comes from his childhood. His mother and siblings gave him the nickname because the name Seán is the Irish variant of the name John, and a common nickname for people called John in Ireland and United Kingdom is Jack. The term “SepticEye” also came from his childhood. When he was still in school, he sustained a severe injury when he was hit in the face with a football while wearing glasses which caused his eye to later become infected, and a bully began calling him "Jack Septic Eye", after figuring out that Seán's mother called him Jack. Seán would later use the nickname as his username.

His home village is Ballycumber in County Offaly, Ireland, where he lived in the countryside with his parents as a kid, later moving with his family to a cabin in the woods.


Seán is the youngest of five, having two brothers and two sisters. His siblings are Allison, Susan, Malcolm, and Simon. Seán has stated that Malcolm currently lives in France, and has an Instagram under the account name malcolmwriter, where he sometimes posts pictures of Seán as well. Seán has previously said that he was really close to one of his sisters growing up, likely Allison as she is closer to him in age. During one of his live streams, Seán mentioned that Allison just recently got married, and while happy for her, he is currently unable to picture himself married.

Seán's father passed away on January 27, 2021.[3] He made a response video couple of weeks later and made it clear that he is trying to move on, despite still being mentally and physically burnt out from what happened in 2020. He later addressed his current mental health problems with Dr. K in the latter's Twitch stream.

Early life

Seán previously lived in an apartment in Athlone, County Westmeath, Ireland, and now currently lives in Brighton, England, though he hasn't done a house tour because he has had trouble with fans going to his house, which makes it unclear if he lives in an office, house or apartment. In a previous apartment, Seán had a roommate named Killian, and he even appeared in some of his videos, including a vlog and a Turbo Dismount video. Seán is very well known for his green hair and is the second most popular "celebrity" in Ireland, though Seán has stated many times how being called a "celebrity" makes him feel uncomfortable.

Seán attended college twice in Ireland, the first time (in Music Technology) he did not finish college, but the second time (in Hotel Management) he returned and he graduated with the degree. Seán has an energetic personality and enjoys playing all sorts of games ranging from AAA games, to flash games, with his favorite games being Shadow of the Colossus, Dark Souls, and Undertale.

He sometimes speaks Irish in his videos, such as various religious songs, and some phrases in Irish (some examples here).


Possibly, all the way back in 2010 to 2012, Jack began dating a Korean girl he got interested in and found online. They were both in different locations, so it was hard for them to closely communicate. Afterward, after several months to a couple of years, he finally got enough money to meet his girlfriend in Korea. They eventually broke up, though the details of the event have never been disclosed.

From early-2015 to August 2018, he had a girlfriend named Signe Hansen (pronounced "sig-neh") from Denmark, whose YouTube channel is Wiishu. She is a digital artist and has often posted fanart of Jack on her Tumblr. At a PAX panel Q&A, Jack stated that he met Signe because she was a fan of his. They started talking on Tumblr and became friends, and eventually started a romantic relationship.

Signe joined Jack and some of his friends - Bob, Wade, and Molly - in his Revelmode charity stream on Twitch when they were playing Overwatch, has been mentioned in a vlog and can be seen in the background with Jack in PewDiePie's PAX 2016 vlog and has a few videos up on her own channel. On February 11th, 2017, for Valentines Day, Signe released a couples' special on her channel. After the video, Jack appeared in several more of her videos. In November 2015, Signe moved in with Jack, and the two lived together in Brighton, UK. On October 9, 2018, Jack announced that he and Signe separated and went their own path. He posted to his Twitter that it was "not an easy decision to make".

On March 15, 2019, it was announced via photos on their respective social media accounts that Seán is in a relationship with Dutch YouTuber Gab Smolders (formerly known as GirlGamerGab).


Jack created his account on February 24, 2007 but did not start uploading videos until November 12, 2012 with his first video being War Has Changed - Solid Snake Impression - MGS4 Intro. His first gameplay video was a Far Cry 3 - Stealth camp gameplay on November 30th.

In the first few years of his YouTube career, Jack referred to himself as the last remaining Bossatronio from the planet Bossatron (Spore). He is friends with PewDiePie, Markiplier, CrankGameplays, LordMinion777, muyskerm, CinnamonToastKen, CoryxKenshin, and many others. He does series on various games, where the episodes of a particular series are spaced out with 3–5 days in between. His favorite game genre is adventure. He has stated that his favorite game is Shadow of the Colossus. Some famous series Seán has done are The Escapists, Subnautica, The Sims 4, Grand Theft Auto 5, SKATE 3, Happy Wheels, No Oxygen Included, Surgeon Simulator VR, Five Nights at Freddy's, and Undertale.

His non-video-game series include: “Reading Your Comments”—in which he responds to comments on either, Twitter, or Tumblr—regular vlogs—in which he shares, talks about his life or what's going around the channel—and used to do a series called “Drawing Your Tweets”, in which he drew things suggested by his fans on Twitter on a whiteboard, be it a real one or a computer program simulating one. He has expressed that in the future he would like to branch out into doing some more skit-based videos.

Jack's friend and editor is Robin Torkar, or pixlpit, as his online alias. Robin has appeared in a Worms Clan Wars video as a secondary player, in "Oh Sir...! - The Insult Simulator" videos, in the "Astroneer" videos, in the "Human Fall Flat" videos, and in the "A Way Out" videos. He is also an animator that has made several animations for Jack, and others such as PewDiePie, Markiplier and the Game Grumps. Robin is the skills behind the Antisepticeye videos, and Jack has publicly thanked him many times for it. Robin is Swedish, which created the nickname "Swedish meatball".

The fanbase created an "evil" Jack, calling him "Antisepticeye." Jack, liking the idea, enlisted Robin's help to add in little glitch edits to his videos to build up the eventual Say Goodbye video on Halloween 2016. As it received a huge amount of support and popularity, Antisepticeye, or Anti for short, appeared as the intro to Jack's PAX East panel in 2016. In 2018, there were small appearances/hints towards the return of Anti, alongside the return of his egos.

Jack started the PMA (Positive Mental Attitude) movement in his video looking back at the year of 2017 (2017 - My Toughest Year on YouTube). It gained a huge momentum among his community and has begun to spread out across the internet. As of 2018, he created and released a long-awaited PMA merch line on his official website Also in 2018, Jack - alongside Markiplier - launched a clothing company called Cloak (with the slogan "Hidden In Plain Sight") which was designed to cater to gamers: stylish, simplistic, and comfortable. Near mid-2020, Jack released his new Coffee Company Top of the Morning, within the first day of being up The Cold Brew pack & Top of the Morning Mug was sold out, with every order made one meal will be donated through the feya foundation to people who need it the most during COVID-19 and in general life.

Some fans pair Markiplier and Jack together as a couple. Their ship name is Septiplier with the catchphrase of, "Septiplier Away!". When Jack announced he had a girlfriend, many people lashed out and hated on Signe for "denying septiplier," even though Jack has stood up to the act and mentioned on Tumblr that he is "still a human" and he deserves the basic right to make his own choices in his life. Other ships include Jelix, which is between Jack and PewDiePie, and Septiishu, which is between Jack and Signe.

Despite his overwhelming popularity, Jack has remained down to earth. He hasn't let his popularity go to his head and admits that he doesn't describe himself as a "celebrity" or "famous," as those terms make him feel uncomfortable. Jack still often interacts with fans, be it on Tumblr reblogging fanart and adding thank you comments, or responding to replies on Twitter. He largely interacts with his community and has definitely shown that he cares.

In addition, Jack has shown himself to be a social activist, where he advocated equality and justice for everyone, especially in June 2020 where BLM movement was at it's another peak, and speaking up for social change and various issues regarding the society and endorsing several democrats.

The PewDiePie shoutout

Jack entered a competition by PewDiePie and was one of 6 YouTubers to win. PewDiePie uploaded the video 'WALL TWERK' in September 2013 and while being amused at Jack's intro, it was shown that Jack only had 2,200 subscribers at this time. After PewDiePie shouted him out, Jack gained just above 10,000 subscribers in a few days, and later on, was rising very fast afterward. Jack shortly made a response video in shock and celebration that he was shouted out, and stated that his phone was blowing up with notifications. Felix and Jack then became friends when Jack had about 2 million subscribers.


Jacksepticeye has six alter-egos, or nine if the fan-made characters "Robbie the Zombie", "Angus the Survival Hunter" and "Bingsepticeye" are counted.

  • Anti or "Antisepticeye" was the fan-fueled concept of a dark, evil and complete opposite version of Jacksepticeye. He was initially idealized by Jack's fans due to his creepy thumbnails and videos. However, Jack has since taken the idea of the character and turned it into a reality, implementing aspects to make the character his own. He is known for appearing with a slit throat, black clothing, gauges, and holding a knife; more recent appearances (as of May 2018) also show him with glowing red eyes. His first appearance was in the Sister Location series on Jack's channel, in which there were glitches and frames including Anti. His first dedicated video was "Say Goodbye" on October 30, 2016.
  • Jackaboy Man is the superhero version of Jack. He is known for having a red bodysuit and a blue mask, and though Jack has yet to portray him with a cape, fans often draw him with one. His first appearance was in the Welcome To the Game series on Jack's channel, and though he also appeared in Jack's South Park series, he has yet to show up in more recent videos.
  • Dr. Schneeplestein is Jack's doctor persona, whose professionality are somewhat questionable. He is typically known for being in a doctor's uniform (scrubs and a white coat) and is currently the only ego who wears glasses, though Jameson does have a monocle. His first appearance was a video in the "Jacksepticeye Power Hour" series, which Marvin also originated from. As of April 2018, after Kill Jacksepticeye featuring Schneep and Anti, he was "missing", and it is highly believed that Anti has something to do with his disappearance. Just after April, on May 3, 2018, Jack made an Instagram post to announce that Schneep has now returned from 'vacation'. His resurfacing was accompanied by an appearance in a surgery video the following day.
  • Chase Brody is a cool "Bro"-stereotype character who was originally meant to parody Dude Perfect. He is the only ego who canonically has children and a wife, though his wife (Stacy) is known to want a divorce and won't allow Chase to see his kids. He is often seen wearing a specific red and grey hat and dark grey shirt and typically has a Nerf gun with him as well. His first appearance was in the "Bro Average" video on Jack's channel. He was in "TIE - A Game About Depression", where it was revealed he had two children with Stacy and deals with the separation (and Jack's coma state) by drinking alcohol. Jack himself has confirmed a future "Bro Average 2" video is on the horizon. His latest appearance was in 'CHASE', which showed Chase has an alcohol problem and most likely depression.
  • Jameson Jackson, also commonly referred to as “JJ” or "Dapper Jack", is an old-timey, black and white silent film character a la Charlie Chaplin. His first appearance was in the Halloween 2017 video "Jacksepticeye - A Silent Film" (which has since been renamed too, making him the youngest, or newest ego by far). His appearance is a white long sleeve shirt and blue vest as well as a monocle and mustache. Being as new as he is, very little is known about this ego and some people even suspect that due to the glitches in the only video he has been in, he either is Anti or is somehow connected to him. He officially received ego status in the spring of 2018. He returned for Halloween 2019 with the video "Jameson Jackson's Jolly Jaunts".
  • Marvin the Magnificent is a magician character. Marvin is commonly known for his blue shirt, black cape, and his white cat mask, which Jack colored himself in the video Marvin appeared in. Marvin's first and currently only appearance was in a video from the JSE Power Hour series. Though not a lot is known about Marvin either, the video gives a good judge of his character, which seems to be cheery and upbeat for the most part. It's assumed that he is bad at magic as well. In May 2018, his image appeared as an easter egg in the background of certain horror game videos Jack posted, but it hasn't been confirmed yet what that means for the egos' story.
  • Robbie the Zombie is a zombie character completely made and supported by the fans. Jack has acknowledged this character a few times, but since Robbie is fan-made, he is not officially considered a part of the egos. He is known for having a striped white and black shirt and having purple hair. He hasn't appeared in any videos due to being fan-made, but the idea for him came from a thumbnail Jack did for a PUBG Zombies video.
  • Bingsepticeye has never shown up in a video but he does exist, though solely by the fans.
  • Angus the Survival Hunter is an Australian wilderness expert who appeared in 10 videos in 2013. Many people consider Angus to be the "OG" ego, due to having appeared first on the channel much earlier than any of the others.

Fan community

There are several games made for him that he played:

There are also several other games (such as Happy Wheels, Turbo Dismount, NoLimits 2, Clustertruck, Little Big Planet 3, Far Cry 4, and Geometry Dash), in which some levels are made for him.

He may not have played every single game, and/or level made for him, but this shouldn't matter because Jack simply loves the fact that people actually make things for him, whether they are good or bad, whether they're real or virtual, whether he's aware of their existence or not.

Jack did a live stream of Happy Wheels #100 on November 26, 2016. And now the longest series on his channel is Reading Your Comments with a total of 107 episodes as of January 6, 2018.

The second one, which is called ALL THE WAY, was published on Seán's channel on July 22, 2016. The song was made by schmoyoho.

  • Jack has never changed his YouTube profile picture and banner throughout his YouTube career or may have last changed it when he was an extremely small YouTuber.
  • During his first play-through of Bendy and the Ink Machine, he revealed that he never wondered what animal Goofy (made by Walt Disney) was until looking at a poster with Boris the Wolf on it.
  • Jack did an online color blind test to see if he is suffering from color blindness, in the online test he failed to put the correct number, Jack acknowledged that he was color-blind, as stated by the online test, so he brought two pairs of color-blind correction glasses (one for inside use and one for outside use).

  • He started saying "Top of the mornin' to ya laddies, my name is .." in the video Maere: When Lights Die - HUGE SCARES - French Indie Horror game - Gameplay/Commentary. According to himself, since he was insecure at the time and initially put on a fake voice that sounded vaguely American, people began thinking his real accent was put on. As such, he decided to play into that by saying the most stereotypically Irish greeting possible as a self-deprecating joke which then became tradition.
  • In college, Jack was a drummer for a heavy metal band called Raised to the Ground. During this time, he wore 10mm spacers in his ears and even had his eyebrow pierced.

  • Despite being Irish, Jack doesn't drink that much. He's often stated that he's the "worst Irishman" because of the fact.
  • In a Q&A live stream, one fan asked why Jack didn't have YouTube Super Chat. He replied that it wasn't yet available in Ireland, but even if it was, Jack wouldn't enable it, since he didn't want to make anyone feel as though they had to donate for him.
  • Jack started out as a fanboy, having looked up to Felix and Mark. They were part of Jack's inspiration for starting his own YouTube channel in the first place.
  • In February 2017, Jack was a guest star in Cr1tikal Charlie's podcast, called The Official Podcast. The timing of the recording wasn't ideal, as it occurred right near the cancellation of Scare PewDiePie Season 2 and the media harassment of Felix. Later in a conversation with a fan on Twitter who asked Jack who his favorite member of the podcast was, Jack replied that Charlie was his dawg.
