INDIVIDUAL: The Deferseara is an Abomination, a being that should not exist and is in and of itself a tremendous blasphemy. The total number of such beings to ever exist in the Nava–Verse, not counting Primal Deities, which straddle several lines, is a single–digit number. Not even Satan himself is as foul and unnatural as them. Genome might come close, though. Each abomination has existed since the second dawn of time, and if true universal peace is ever to be attained, they all absolutely must be destroyed. No one has ever managed to destroy one.
The Deferseara is a slug–like monstrosity several hundred feet long and about one hundred feet in girth that emerged from the Abyss of Infinite Death, which NOTHING is supposed to come out of, and teleports throughout the Nava–Verse's multiple planes, appearing inside of planets, eating parts of their mantles and staying in one place for cycles at a time. It can withstand the most extreme of conditions, and barely anything can hurt it. Its durability value is completely unknown and likely in the range of hundreds of thousands. The beast can release highly acidic vomit in doses of hundreds of gallons at once, which is not a product of any natural digestive system but rather comes from a portal in the Deferseara's body to a horrible dimension filled with nothing but this deadly yellow fluid, which can eat through solid rock. No mortal has ever met this creature in person. It is only thanks to divine intervention that the Custodian of the Nava–Verse even knows of its existence.
The abomination's body is truly inexplicable. The rear end consists of a slimy purple tail covered with bloody spots ending in a monstrously deformed human head with several indestructible appendages growing from its pores, which connect to the rest of the Deferseara's body: a patchwork mess of a mass of parts that should never go together as well as a few random objects including a giant castration tool and even features of animals from Earth, with a giant three–buttocked anus for a mouth.
A handful of planets have suffered significant damage to their interiors thanks to the Deferseara, though thankfully none have sustained enough decay to collapse… yet. Some have interpreted a certain verse of the Next Testament to be referring to this monster, and if this is true then it will have some sort of role in the eventual End Times and the (second) final battle between Good and Evil.
CREATURES (Synthetic): These Skellen Abominations are artificial beings that lack a proper name and do not deserve one, as they are among the most unholy of monstrosities ever to be manufactured by one of the most evil races in existence. They are not considered true Abominations in the cosmic sense despite their moniker. These two particular samples were among the first successful experiments produced by the Skellen in the mid–Sixth Century Relative, specifically around the time of the Vision Wars, with some assistance from Cosmo’rath. Both are made from the body parts of various different creatures, with many mechanical parts and steroids added. They were made for the sole purpose of killing and likely are not even sentient. On the left is what is known as "Model A-Q-X", a giant blob used as a unit in space battles. Nearly fifty cubic feet in mass, this specimen can fire multiple types of destructive beams from its "eyes" and has a durability value over 2,000. On the right is "Model C-J-S", a roughly humanoid ground unit grafted onto a form of tank treading. This creature was once meant to replace a portion of the Skellen military's infantry, but it proved quite ineffective in battle and quickly disappeared from the Prime Galaxy. Its durability value was probably about 500.
