Darkhold is an 2021 miniseries by Marvel Comics written by Steve Orlando with art by Cian Tormey.
When Doctor Doom uncovers the Darkhold, the Scarlet Witch races to stop him from using it to cause chaos, but she is too late. Doom has accidentally woken Chthon from his slumber in the other-realm, and now he risks laying destruction to the Marvel Universe.
In an attempt to stop him, Wanda summons a ragtag group of heroes (Iron Man, Blade, The Wasp, Spider-Man, and Black Bolt) to act as the Darkhold Defenders. Having to read from the Darkhold itself to gain the power to enter the other-realm and defeat Chthon, the Darkhold Defenders must face their worst nightmares and corruption by the Darkhold to stand a chance of succeeding.

Darkhold provides examples of:
- Aborted Arc: Darkhold: Omega ends with Wanda assimilating Chthon into herself and becoming the Goddess of Chaos, warning that if she dies Chthon will be unleashed... but Wanda dies in the lead-up to the X-Men: The Trial of Magneto and nothing of the sort happens.
- Anthology: Besides Darkhold: Alpha and Darkhold: Omega, each issue shows what each hero lived for
- Artifact of Doom: The Darkhold is a Tome of Eldritch Lore penned by Chthon to serve as a foothold in Earth's dimension after his banishment from it.
- Body Horror: The version of Iron Man created by the Darkhold intended to make his armor into a mobile hospital that could heal injuries, but the armor's programming goes wrong and leads to it trying to permanently bond with Tony; at one point he tries to remove the armor and ends up tearing off his own skin. Hoping he can protect people from all diseases, Tony proceeds to convert everyone by producing and putting them into said suits.
- The Bus Came Back: Black Bolt returns after three years of the Inhumans being essentially shelved after Death of the Inhumans.
- The Corruption: The Darkhold twists everyone who reads it, and it's especially potent here because it's the original copy created directly from Chthon's own flesh. All the heroes who read it are corrupted into the absolute worse version of themselves.
- Dissonant Serenity: Tony remains his cheerful, rogueish self the entire time while he's affected by the Darkhold.
- Humanoid Abomination: In contrast to his original grey-skinned blue-cloaked form and giant blue-skinned Cthulhumanoid-esque form from Carnage Vol. 2, Chthon takes the shape of a pale-skinned humanoid with long horns and a red cape.
- Identity Amnesia: Black Bolt's vision in the Darkhold creates a timeline where he may be Maximus having been "programmed" to believe that he is the true Black Bolt after altering his body and memories as part of a plan to attack his brother.
- Obliviously Evil: Tony becomes this in his Darkhold form, believing that he's helping humanity and protecting them of all disease by shutting them into his suits and binding their flesh to steel.
- Sealed Inside a Person-Shaped Can: In Darkhold: Omega, Wanda binds the True Darkhold to her soul and seals Chthon into herself, gaining all his powers for as long as she lives.
- Tome of Eldritch Lore: The titular book is the typical example for the Marvel Universe but it's ramped up because it's the original copy. Reading it is likely to melt someone's face or possess them with eldritch power and make them thralls of Chthon.
