Penitent Engine

From 1d4chan
Closest thing to give a Tech Priest a boner that isn't some old microwave or junk.

Penitent Engines are mechanical engines piloted by heretics who are guilty of a terrible crime and want to atone for their sins. As usual they are the main walkers for the Bolter Bitches Nuns with Guns. Thus they are given one of the worst imaginable punishments available to the Imperium. A multitude of wires and chemical injectors are implanted into the heretic's spine, which are then attached to a mechanical suit of destruction. When not engaged in combat, their chemical implants inject feelings of guilt and pain directly into their brains, reminding them on how much they fucked up in life. Driven by their pilot's frantic need for forgiveness, Penitent Engines charge towards enemy forces heedless of danger, knowing that only in death can forgiveness be earned. Since 1) half of the models are female 2) they're part of the SoB codex and 3) the Ecclesiarchy prefers to put its servants in penitent engines rather than execute them when they're found wanting, /tg/ likes to pretend that all pilots are former sisters, even if you're more likely to find a particularly nasty heretic crewing one than a defrocked priest or Sororitas.

While somewhat Grimdark, it is kind of offset by the fact that the pilots of Penitent Engines are considered strangely hot and sexy by /tg/. Whether is due to the fact that the female pilot gets all the art, getting 'penetrated' and 'wrapped' around with so many wires like some kind of kinky bondage film or the fact that they are quite scantily clad in a single cloth robe is unknown, although most would point towards the former. Like the fucking baby carrier, the Penitent Engine suffers the general failure of exposing the driver to the elements. While it is to keep with the whole "dying gloriously in battle" shtick, they could at least put some cover so that the pilot could actually reach their enemies rather than getting sniped after immediately disembarking from a ship. Allegedly the chemical cocktail the drivers are drugged with gives them an insane endurance while letting them feel each wound so the fact their heads are likely to have gaping holes in it within a few seconds is actually intended. It helps that the people fielding Penitent Engines don't particularly like the people in them. Additionally the fluff states that pilots are left mostly exposed as a deliberate decision, to ensure that the penitent is protected solely by the Emperor's will rather than cowering behind ceramite plating.

See also Arco-flagellants, which are the same general concept but for slightly less naughty heretics.


Penitent Engines are typically armed with close-combat Dreadnought-class weapons such as a large, circulating power saws, Chainfists, or other Power Blades on each of the walker's arms, as well as Flamers or Heavy Flamers, which can be fired together or separately. The Penitent Engine can also use its legs to kick or stomp on enemy infantry since unlike the Dreadnought, the Penitent Engine doesn't have short, stubby legs. Mortifiers and Anchorites are further equipped with heavy bolters or extra heavy flamers.

New Release[edit]

Yes, in plastic now. First appearing in the limited-edition army set you missed out on a copy of, then confirmed to get a multipart release in 2020. Now features an alternate build, the Mortifier, which is where the female pilot option went.
