Antisepticeye (Anti for short) is a fan made alter ego/split personality of Jacksepticeye. He was initially created by Jack's fans due to his creepy thumbnails and videos. 

In short, Antisepticeye is a darker, evil version of Jacksepticeye. The general idea of Anti's character is that he's a demon or virus that is fighting for control over Jack's mortal body. Antisepticeye's personality is usually demented and with a strong desire to harm others. It is thought that the fan-made Darkiplier had fueled the idea of Antisepticeye.

Not much is 'canon' with Antisepticeye, so fans often make their own material.

Video appearances (2016)Edit

In Facerig episode three, Jack uses a flower face named Flowey from Undertale; while using it he says "down here, it's kill or be killed." After this, Antisepticeye's laugh is heard, however Jack might just be goofing around.

Since the beginning of October 2016, there have been brief clips within Jack's videos that resemble Antisepticeye. They began in his playthrough of Five Nights At Freddy's Sister Location. In the description of these videos, there are ominous messages and sometimes links using zalgo font that add to the persona. As well, Jack's twitter and tumblr accounts have featured the same font and personality, suggesting Antisepticeye is "taking over". Even in videos where Antisepticeye isn't present, the white board on the door will occasionally contain vague messages that relate to him. When fans ask about or point out Antisepticeye, Jack responds as if not knowing who they're talking about.

Additionally, Jack's Twitter account has changed from Jacksepticeye to A̸͢n҉t͞isepticeye.

On Halloween (31 Oct 2016) Jack made this video, officially confirming Antisepticeye's arrival. In this video, Jack is seemingly recording an innocent vlog of him carving a pumpkin (similar to the previous year, 2015). The white board on the door has the words "Happy Halloween!" written on it. As the video continues, an eerie laugh is heard and the camera becomes distorted. Jack briefly steps away from the camera to investigate. He returns to the camera, acting rather strangely, and continues carving the pumpkin. Then, the sound of someone stomping can be heard, and Jack once again leaves to look for the source of the sound. At random intervals, the camera turns distorted just as before, but Jack remains oblivious. At one point in the video Jack's nose starts to bleed and he briefly steps away from the camera to get some tissue. When he comes back he pretends it never happened. Towards the end of the video, Jack stares blankly at the camera and begins to slit his throat with the knife in his hand, causing him to bleed to death and fall onto his pumpkin. After many seconds of silence, Anti possesses Jack and jumpscares the viewers. The words on the whiteboard are now scribbled out. Anti jeers at the viewers, blaming them for Jack's death. He says the viewers could've stopped him from doing it, but they just watched. He declares that Jack is "gone forever" and asks the viewers to say their goodbyes. Finally, the video cuts to black and ends.

Video appearances (2017)Edit

In January 2017, the all too familiar static and sounds can be heard in Jack's videos.


Anti (left) and Dark (right)

On 28th July 2017, Markiplier made a video on his channel titled "DARKIPLIER vs ANTISEPTICEYE". During the video, the two were arguing about who should be "king" of their "realm" (dubbed "YouTube Hell" in the comments). The two were about to fight, however they were constantly disrupted by other YouTubers dark sides (ABlazingPhil (AmazingPhil), DannyDarko (DanTDM), Sharkyoho (Schmoyoho), etc). Then Chica, Dark's dog, appears and sucks the other dark sides into a void. She becomes angered, saying that Dark didn't feed her. As Dark panics, Anti stares at the screen (actually staring at Chica), laughing. Anti played a more insane role than a serious, evil one.

On 3rd August 2017, Anti appears in Bio Inc. Redemption. At the start of the video, Jack explains that the developers made an Easter egg of him in the game. Then he starts feeling 'sick', so rushes off camera. Dr. Schneeplestein replaces him and vows to save Jack in game. Halfway through, Dr Schneeplestein himself complains of discomfort and makes references about death and Anti (such as 'antidepressants'). Anti glitches into the face cam and game more frequently, taking over Dr. Schneeplestein. When in-game Jack finally dies, Anti appears. He berates the viewers by saying he's tired of repeating the same cycle (to quote: "How many times must I do this? Again and Again! OVER and OVER! FUCKING CIRCLES!") meaning he is tired of killing Jack just so Anti can appear to please the audience. He also mocks the viewers when they call him "glitch bitch" (a nickname fans gave him online). He asks a few questions, such as "who do you think you've been watching all this time?" responding with "my puppets." He states that this is his world and this isn't the end of him. The video cuts to black as he giggles and says "see you soon."

On the 25th of October 2017 sounds and effects related to Antisepticeye appears in Opening Tour Gifts. When he receives a knitted Anti doll, Jack says, "little anti. Look at him glitching out all over the place." A sound of giggling can be heard and the screen glitches. This happens a second time when Jack presents a painting of Anti someone made for him, with the screen glitching.

During the 27th October while Jack and Robin play Overwatch and Robin fall to his death after jumping himself to it, Jack made a little giggle laugh, but it was unsure if it was Anti who was laughing.

On Jack's Twitter you can also see tiny glitches if you look closer.

On 31st October 2017, Jack makes a pumpkin carving video for the third time. He starts the video off normally, but then suddenly changes to black and white 1930's silent movie style, complete with appropiate attire. He carves the pumpkin with a face drawn on it similar to his own face. Towards the 5:25 mark, he accidentally cuts himself. While treating himself, Anti starts gliching into the scene, taking over Jack's new persona. He makes the slitting throat action and leans towards the camera, while title cards show up on screen saying 'Puppet' and 'SMILE'. The video ends with Jack performing the usual outro.

It's time to DIE!

His body was weak!

You all said my name

You wanted me here, so here I am

You could've stopped me, but you just watched, as this happened!

I'm here now

You listen to me!

Say goodbye

Forgotten? Or just too afraid to remember?

I've been here this entire time, keeping an eye on things

You found someone to replace me, threw me aside

You stopped paying attention

Always there, always watching

Enjoy the show

You're weak, just like HIM!

Why don't you put on more makeup? I've already won!

This world is mine! These people are mine!

Why didn't you feed your dog?!

I am in control!

That "doctor" thought he could save him, but he was mine! He was WEAK!

Mocking me with your "glitch bitch"

I am eternal!

Who do you think you've been watching all this time?

Just my puppets

If you wanted him back so badly, then why don't YOU save him?

This is my world!

Well there are no strings on me

I wonder what will happen to your favourite boy next time

This isn't over

See you soon


Still here



Watching Over You! (Jack's title for Overwatch live stream)

he's not coming back

You did this

It feels good knowing what you did

What kind of person

*Corrupted/Glitchy Voice* Are you? (Instead of "You are")

you failed him

it's your fault

you're already out for blood

what are you waiting for?

go then

see you were hope takes you

Can you feel it?

He's waiting, for you

You Can't Fight Him

You're not Ready

The StOry ends here

Good luck kid

you're going to need it were right...

Your story isn't over

But his is

How touching

am i interrupting you?

He earned it

you both did

you can't stop me

Not yet

Don't worry

you'll get your chance

Why don't we step outside for a little bit


See you next time!


the most thoughtful person

restart the game

there you are (no glitches but creepy talking)

Help me, Jack!
