Now we move onto one of the most famous scp and being the most dangerous and it is the hard to reptile or scp-682. This scp can speak human language and has knowledge from the past and saying it was there during the nuclear era. It has to be subdue in acid bath and chained up so it won't move. 

Classification: Keter class Anomalous 

Powers and abilities: superhuman physical characteristic, immortality(type 1,2,3, and 9, stated by Dr. Gears to simply a shell formed by 682 true form, and that damaging said shell in a way it is like shaving the hair off a human: annoying, but not deadly, stated by Dr. Crow to be simply a projection of the true 682 into our reality, with attacking it being the equivalent of poking your finger in a balloon: your inside but still outside), large size(type 0), regeneration(at least high mid[able to regenerate from being torn to pieces, regenerated from only 7% of its body], low godly over time), natural weaponry, size manipulation, genius intelligence, reactive evolution, adaption, berserk mode(can enter a "rage state" where it blindly attacks the closest living target), absorption(able to consume and absorb any material and gain energy from it), non-corporeal(described as coming from somewhere where time, space and states of matter operate very differently than they do, and that 682 as we know it isn't a corporeal being), reality warping(can create localized space-time anomalies as a defense mechanism. These anomalies are similar to both the sudden appearance of a black hole or the theoretical event of a sudden hole forming between our dimension and another and are capable of forcing aside the very fabric of reality), black hole creation, resistance to acid(adapted to resist being submerged in Hydrochloric acid), death manipulation(682 is neither alive or dead in the traditional sense), mind manipulation(resisted the effects of scp-061), and petrification/transmutation(resisted scp-409's ability to completely crystallize any material into quartz)

Attack potency: Small building level(described as having extremely high strength, has destroyed its containment chamber, a 5m x 5m chamber with 25cm reinforced acid resistant steel plating, multiple times,  a feat which would yield 3409960000 Joules total, or 0815 tons. Fought with scp-076 who is able to harm it) At least small building level, likely higher(Demolished a small skyscraper on one of its rampages, killed scp-076 and severely wounded scp-083-D), varies via reactive evolution, adaptation and power absorption(Its power increases proportional to the power used it against it, and due to this it has adapted to levels ranging from dispersing a massive nimbus cloud to growing to the size of Saturn and destroying/devouring the nearby planets throughout the solar system to potentially absorbing the power of the solar system destroying the black hole that is scp-123 to growing large enough to consume multiple galaxies and rival the universe in size), universe level+ via dying(Stated here that scp 682 is a universal constant, when it dies the universal it inhabitants will cease to exist) Hyper verse level(The offspring of A'zieb and the scarlet king. The army of Leviathan is capable of causing severe damage to the roots of the tree of Knowledge from all creation stems)

Speed: Unknown(Described as having extremely high speed and reflexes)| Superhuman(Can outrun mobile task force units, who are all physically peaked soldiers) with supersonic reactions and combat speed(kept up with scp-076), potentially up to Massively FTL via power absorption, reaction evolution, adaption(was able to being thrown around at the speed of light. Adapted to become as large as Saturn and was able to easily and was able to easily traverse the solar system. Grew to be large enough to dwarf multiple galaxies simultaneously).

Lifting strength: unknown| Class 25(Was able to lift and swing scp-162 around as a weapon), potentially Multi-Galactic, potentially higher via power absorption, reactive evolution, and adaption.

Striking strength: Small building class

Durability: Small building class(Described as having extremely high strength), regeneration, reactive evolution, adaption, and immortality make it extremely difficult to kill(682's body is just the 3-dimensional shell of an extra dimensional being),at least Small Building level, likely higher(Was unaffected by being struck multiple times by natural lighting), varies via reactive evolution, adaption, and power absorption, regeneration and immortality makes it extremely difficult to kill(SCP-738 stated that it would be impossible to destroy 682 without causing serious damage to or outright destroying the universe, scp-2855 was unable to do anything to 682, scp-001(Dr. Clefs proposal) was unable to kill 682 and only knocked it out after striking it multiple times, 682 is unable to even kill itself, 682 body is an incorporeal countless dimension being trapped in a 3-dimensional shell, cannot be killed as scp-343 will not allow it to die)

Stamina: limitless

Range: Standard melee range

Standard equipment: none

Intelligence: Genius conventionally(Able to engage in complex communication with scp-079, a sentient and constantly learning and evolve), animalistic in combat(Has shown little by way of combat strategy other than wildly attacking in range) Genius(Despite its reputation as a berserk monster, scp-682 is actually extremely intelligence, with its intellect being widely recognized such as the Serpent Hand. It has shown knowledge numerous SCPs, some of which it shown to have more knowledge on than the Foundation itself, even going so far as to engage in complex communication with scp-079, a sentient and constantly learning and evolving AI. SCP-682 has also demonstrated vast knowledge of the multiverse and the supernatural due to retaining all of its memories from its past life as Leviathan).

Weakness: none notable| A few scps have been able to tame 682, including Scp-999, who literally tickled him into submission(Though this only worked for a very short time and was due to 999 heritage as an offspring of the Scarlet King and the nature of its power) and scp-053, a little girl who temporarily rendered him docile(Though this is also due to scp-053 heritage as an offspring of the Scarlet king)

Note 1: SCP-682 being sent to the Ravel woods for several years only took so long to escape due to the extreme extensive and powerful ritual used to send it there as well as the natural of Ravel woods itself, as the Ravelwoods runs parallel to the Wander Library, is only accessible and escapable through temporarily constructed ways, and the background magic rejecting that of the library makes exit via ways nigh-impossible. 682, however, cannot enter ways and is barred from entering the library at all, meaning that it escaped under its own power from a place that by all intents and purpose should have been impossible for it to escape.

Note 2: Regarding SCP-682 immorality. 682 is a shell bound to the 3-D world by 343, but the shell itself is a projection of 682 former self that is generated by 682 higher-dimension consciousness.
