Some of the most dangerous groups and individuals in the Adamsphere/Reality 6:
The cult of Hinn Óreiðukenndi;This refers to entities that have had encountered with Hinn and have thus been consumed by the memetic hazard. The entity is one of the few individuals that is able to unite every multiverse ruler within the Adamsphere to take action against the threat. Hinn's been reported to have the largest cult across the Adamsphere though the numbers had reportedly lowered when the entity attempted to engage The White Demon in a fight.
Nihility;The name of a cult lead by a Gaster of an unknown AU. The most defining feature of the cult is their ideology, following one of Nihilism and that nothing matters in the Adamsphere. It is made up of several outcodes that despaired upon discovering the various multiverses and realizing that no choice they ever made mattered as somebody out there made it already and even made a better one. The goals of this cult is unknown except for a few rumors which state that they have the goal of reducing all of Adamsphere to one singular universe.
The Plague Doctor:Rather than a cult, The Plague Doctor is a rogue Gaster variant from an unknown AU. Unlike the others, The Plague Doctor's goals are clear due to the individual's actions. The Plague Doctor aims to merge all of Adamsphere into one giant amalgamation, being of the thought that such an entity would be capable of fighting off the Creators. Many multiverses have already fallen to the Plague Doctor and his army, transformed into large amalgamations that do his bidding. The Plague Doctor's strength comes not in physical parameters but rather due to his servants, an Asgore and Undyne amalgamation he made after combining after several multiverse ruler variants of the aforementioned individuals.
Nightmare:The most well known threat to the Adamsphere and the entity who for a brief period ruled the Adamsphere. It is without a doubt that Nightmare is the biggest threat known to Adamsphere to this date, only briefly eclipsed by the first Error. Nightmare's properties and his status as a Conceptual Embodiment of Negativity makes him a threat that is nigh impossible to beat in a physical or mental battle with only the first Error!Sans and Dream being recorded to have beaten him. Nightmare himself commands a vast army of multiverses he conquered during the Adamsphere Incineration Incident and has largest military force of all multiverse rulers and the third greatest empire in terms of might, only rivalled by King Originverse and surpassed by the original King Multiverse.
The Devil's Gladiators:This refers to a cult of Errors and destroyers that have taken to worshipping the original Error!Sans to a fanatical degree, replicating his actions and his way of destruction to near perfection. One of their main goals to this date is to locate their 'God' as they don't believe of the original Error's death, wanting him to command them all. Their secondary goal is the complete and utter destruction of the Adamsphere, seeing it all as worthless.
