SCP-2317 is an Apollyon-class object, and is known to be an unavoidable cause of one if not many XK-Class Scenarios (world-ending events). It is, in short, an enormous entity of another universe bound to ours via a dimensional portal opened in the 19th century. Ever since, every chain restraining the being has been broken by some corresponding event in our universe. Six of the seven total chains restraining SCP-2317 have been broken. The final chain is projected to be broken within the next thirty years.
In the event of its escape, the SCP Foundation has made plans to escape the planet or in some other way preserve the safety of mankind after the inevitable destruction of Earth.
Powers and Stats
Tier: At least 5-B, probably far higher
Name: SCP-2317, "Devourer of Worlds"

Classification: Apollyon-Class Entity
Powers and Abilities: Superhuman Physical Characteristics, Resistance to Sealing, Possibly Telepathy or Probability Manipulation (Based on its link to our universe, two possibilities exist; it must either, A., somehow be able to detect catastrophe in our world, or B., cause it), Destruction
Attack Potency: At least Planet level (Stated to be capable of causing multiple XK-Class Scenarios simply by entering our universe, flat-out stated to be able and undeniably was going to destroy Earth), probably far higher (Suggested to be able to impact the universe on a much larger scale)
Speed: Massively Hypersonic+ (Its body fills up a 100 km^3 area when hunched over in a ball; its estimated height is 200 km; for reference, Mount Everest isn't even 9 km. It is 120,846 times larger than the average human, and would therefore travel roughly the same amount of times faster, leaving it squarely at Mach 2220)
Lifting Strength: At least Class P+ (SCP-2317's sheer size puts him in this level of physical strength)
Striking Strength: Class XJ

Range: Hundreds of kilometers by sheer size, planetary otherwise
Standard Equipment: None
Weaknesses: Can be bound again only by the sinews of other Devourer entities (however it is unknown how mankind discovered the original sinews in the first place)
