Jack's Enemy Within. He's had a few cameos and one major appearance in the 2016 Halloween episode.
- Ax-Crazy: In Say Goodbye, he's introduced before taking over Jack's body and slitting his throat.
- Big Bad: Just as Darkiplier is the main villain for Mark's channel, it's safe to say that Anti is this trope for Jack. Humorously, the two (Anti and Dark) see each other as The Rival.
- Black Eyes of Evil: He has these in several glitches, which gives him a slightly insect-like look.
- Demonic Possession/Split Personality Take Over: It's unclear as to what Anti really is, so it wouldn't be incorrect to assume that either one of these events occurred during Say Goodbye.
- Enemy Within: Shares a body with Jack.
- Expy: Anti originally was a fanon evil version of Jack that was reminiscent of Darkiplier. Later averted when Jack decided to create his own version of the character.
- Acknowledged here◊.
- Fun with Acronyms: This Instagram post uses "Anti" to form the backronym "And Now Tempting Inside".
- A God Am I: It's subtle, but it's there. In "DARKIPLIER vs ANTISEPTICEYE", he says "This world is mine! These people are mine!"
- Hostile Show Takeover: Implied. Jack's answer to people freaking out about Anti's return was "he never left".
- Interface Screw: His presence causes this in videos (see Ominous Visual Glitch below), as well as in text-based messages like Instagram post captions, YouTube captions, and tweets; whenever he's near, text becomes Zalgofied.
- Ironic Name: Antiseptic is another word for a healing cure.
- Knight of Cerebus: He managed to turn an innocent little pumpkin-carving vlog into something much more sinister.
- Kubrick Stare: Done here while sporting an eerie black hood that makes him look awfully like Darth Sidious.
- Large Ham: As per Jack's personality, he tends to be rather theatrical.
- Laughing Mad: Does this frequently.
- Leitmotif: Downplayed example, but anytime he makes a cameo, high-pitched static can be heard.
- Manipulative Bastard: Has no problem using other people as pawns to further his ideas, including Jack's friend Dr. Schneeplestein, and boasts about the amount of control he possesses over all.
- Nightmare Fuel Station Attendant
- Ominous Visual Glitch: Anti first appeared in the the form of green Freeze-Frame Bonus glitches in Jack's video webcam for the duration of October 2016. He can be seen making odd and jerky movements, with the occasional Slasher Smile.
- Real Men Wear Pink: Sean once jokingly said Anti's into crotcheting.
- "The Reason You Suck" Speech: He gives one that is directed at Jack, though he faces the audience as he says it.
- Slashed Throat: After Say Goodbye, he has a knife wound on his throat, helping to differentiate himself from his non-possessed counterpart.
- Slasher Smile: Enjoys giving out lots of sinister grins.
- Smug Snake: He shows shades of this, claiming everything that isn't him is weak.
- Voice of the Legion: His growly, scratchy voice sounds as though it's been corrupted and overlaid with Jack's voice.
- A Day in the Limelight: The "CHASE" video.
- Affectionate Parody: Of the trickshot videos popularized by Dude Perfect. His trickshots are not instantaneous and are often preceded by ample failure.
- Break the Cutie: At the end of the TIE playthrough, it turns outfit AQ that his wife divorced from him, he only sees his kids on weekends and his best friend Jack is in a coma. In the third part of Stories Untold you can hear his broken voice saying: 'Jack, this is Chase. You need to wake up...'
- Broken Tears: Breaks down weeping after he tries talking to one of his kids on the phone only for them to hang up on him.
- Comical Overreacting: Just like Dude Perfect, Chase screams and loses his mind when he makes a trickshot (usually due to how long it takes for him to make one).
- Dramatic Wind: Is seen posing with his hair blowing several times...only for the camera to pan and reveal that he's using an ordinary metal fan.
- Driven to Suicide: Commits suicide with his Nerf gun in his final trick, "Stacy, I Love You (Please Don't Go)".
- Foot-Dragging Divorcee: His dedication to perfecting his trickshots has estranged him from his wife to the point that she is threatening to divorce him and take their children with her.
- Fratbro: Parodied and played for laughs.
- Large Ham: Has a tendency to yell loudly when he completes a trickshot.
- Nice Hat: Wears a trademark snapback.
- The Perfectionist: He's committed to mastering his trickshots to a fault; it leaves him with no time to be a father or a husband, which is why his family has effectively disowned him.
- Reality Ensues: He deconstructs trickshot videos by showing what would normally be edited out. His trickshots take long times to complete and he misses a lot.
Henrik Von Schneeplestein
- Appears in: The Jacksepticeye Power Hour - Dr. Septiceye, Amateur Surgeon Christmas Edition (playthrough), KILL JACKSEPTICEYE | Bio Inc. Redemption (playthrough)
- Blue Is Heroic: He normally wears a blue shirt and mask to match his eyes, with an additional blue cap on occasion. This trope properly comes into play in the "KILL JACKSEPTICEYE" video, in which which Schneeplestein serves as an Anti-Hero trying to save Jack from death while trying to resist posessesion from Anti. In this case, his blue colour scheme contrasts Anti's green.

- Lethally Stupid: Has killed several patients as a result of his incompetence.
- Mind-Control Eyes: The glitches in the "KILL JACKSEPTICEYE" video make his eyes flash green/blue, possibly to signify Anti taking over his body.

- OOC Is Serious Business: Gets increasingly unwound in the Bio Inc Redemption video where he's trying to operate on Jack and all of his efforts to help him only make things worse.
- Unwitting Pawn: Becomes one for Anti against his will.

- Fat Bastard: Labelled this by some of the inmates, as they found him disgusting to look at. He was definitely in better shape than Kampas Krismas, though.
- Genius Ditz: Was considered incredibly unintelligent by the other inmates, and was unable to use a computer, but could assemble knives and assault weapons with ease.
- Handicapped Badass: In Episode 3 he gets his hand shot off by a guard after going on a rampage with a machine gun. Doesn't stop him from beating other people up though. He bleeds out from his bloodied stump in Episode 4, though.
- Killed Off for Real: In Episode 4 he dies on the floor, with another inmate standing on top of his corpse.
- Men Don't Cry: Averted. Foster spent almost as much time breaking down in tears as he did tripping.
- Mysterious Past: He was sent to prison for murder, but we have no idea whose, and he had quite a reputation before he started getting beaten up constantly.
- Pose of Supplication: Adopted this whenever he broke down crying.
- Sudden Sequel Death SyndromeDies two minutes in to Episode 4, after bleeding out from his injuries.
- Awesome Mc Coolname: Invoked by Jack when he entered the character creator, seeing it was the default name, and chose it because of how cool it was.
- The Chessmaster: Managed to manipulate his way through his jail time, both the guards, inmates, and even a judge.
- Chronic Back Stabbing Disorder: Betrayed people left and right to survive, crossing practically all the gangs at one point or another.
- Earn Your Happy Ending: Subverted. Jack reached the end of his sentence with Kampas Krismas, but his stats weren't high enough to leave prison. Jack used cheats to get him high enough, allowing Krismas to go on and lead a happy life.
- Fat Bastard: Spent most of his time in prison with a lot of excess weight, and was a devious double-crosser, but lost most of the gained weight by the time he was released.
- Genius Bruiser: Subverted. Much more intelligent than Dan Foster, Krismas was smart enough to use the computer, and to get rich making drugs, letting him buy off other inmates for protection. He wasn't much of a fighter though, although he could hold his own here and there.
- Hooker with a Heart of Gold: Was jailed for prostitution, and has a wife and kids waiting for him. He tells his children that he's a secret agent, though.
- Stout Strength: Though not as strong as Dan Foster, Kampas Krismas had muscle hidden beneath his girth.
MaverickA man trying to get Kampas Krismas to infiltrate The Avatars of Allah gang. He was at one point murdered, but returned from the dead to needle Krismas.
- Back from the Dead: The word of his death passed through the inmates and the guards, but he showed up to berate Krismas for not completing a misssion anyways.
- Faking the Dead: Presumably, otherwise Maverick's ghost showed up to tell off Krismas for not joining the Avatars of Allah.
- Posthumous Character: We didn't get to see anything of him until after he was "dead".
- Unexplained Recovery: He was murdered. It didn't stop him from choosing to never rely on Krismas for a mission again.
Obie LovedayA new inmate that arrived shortly after Krismas did. Within days, he was running one of the more powerful gangs in the prison. After his release, he went on a killing spree upon finding his wife having an affair.
Like Felix before him, Jack has accumulated a lot of pets in Minecraft.
