Helliam

Helliam is the slash ship between William Afton and Henry Emily from the Five Nights at Freddy's fandom.

FFPS - Puppet Minigame
It was proven that William was the murderer of Charlie; Henry's daughter, via the Puppet Minigame. You start by controlling the puppet, given the instructions to touch a child with a green accessory. After playing the game multiple times, a child with a green bracelet, named Charlie, is trapped outside of the establishment. After the child fades into the darkness, you must leave the building and touch the, now dead, Charlie, which then ends the minigame. It has been confirmed that her murderer was no other than William Afton.

FFPS - Henry's Voice Lines
It was also proposed that William and Henry were past business partners and old friends. This can be assumed due to from Henry's voice lines in Freddy Fazbear's Pizzeria Simulator, referring to his "old friend" while a visual of Scraptrap (William) appearing on the screen. Henry is angry about what his old friend had done to her daughter, wishing that William would be sent to Hell. His voicelines end by Henry burning down the building and everything inside, in an attempt to destroy what William had made of his creations, and set the souls of his murder victims free.

Trilogy - The Silver Eyes
In the Silver Eyes (first book of the trilogy), it was theorized that William practically worshipped Henry for his success. Though it was also theorized that William also had a hatred for Henry due to his success. In the graphic novel, in many of the pictures where William and Henry are together, Henry's expression shows fear and/or nervousness. The scene is set in the abandoned Freddy Fazbear's, however William and Henry have not many connections shown in the story, Other than the times where Charlie has flashbacks of both her father and William.

UCN - Old Man Consequences
In the Old Man Consequences cutscene, you can hear a raspy voice, (presumably William's) calling out for his son Michael and Henry to help him out of Hell. There is not much significance to this cutscene, however, it shows that William still finds use in his old friend.

Fanon
Helliam is a semi-popular ship in the Five Nights at Freddy's fandom. It soon peaked in popularity, most likely after the release of FFPS. People learned that Henry was William's business partner, and they thought, "Why not?"

Helliam's rival ships would be Willara, Hemilee, and (maybe?) Ballortrap.

On AO3, the ship currently has over 590 works.
