Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX must be kept in a cell that is 3 meters wide and 2 meters high. The walls must be composed of an alloy of iron and stainless steel. There needs to be at least 2 ledges for the entity to move around and stay in average physical condition. The cell must be cleaned 3 times a week and raw meat must be provided 4 times per day. All personnel are permitted to enter while exercising caution. Trained handlers are permitted to amuse SCP-XXXX if the organism becomes bored and the entity must be spoken to calmly and non-threateningly, not to provoke aggression. Ignoring these rules will end in serious repercussions.
Description: SCP-XXXX has a physiology similar to that of a panther weighing around 13 kg (30 lbs). Subject's body is rough with a width of 30cm and a height of 45 cm. The body has a dense layer of skin, approximately 7 cm, and its anatomy is similar to one of a panther's. However, research has shown that the left prefrontal cortex, left temporal cortex and parietal cortex are developing further than a panther would. The frontal canines and multiple molars, in particular, have already grown to the size of an adult lion's while there are many signs suggesting the entity is still developing. The surface of the skin is built up of blue and orange hair. The organism has a verdant blood color. Subject's temperament is playful at times, releasing a vibrant sound similar to that of a cat. Despite this SCP-XXXX ruthlessly bites and scratches when provoked, causing punctures in the forehead. At capture, SCP-XXXX opened a rift that researchers currently believe leads to a molecular environment with entities that share similarities with giant bacteria. In containment, the organism has not been able to replicate this ability yet and, as of yet, no further information has been found. Because of its increased intelligence, the entity can understand humans perfectly which, fortunately, makes research and experiments easier. When trying to conjure a rift SCP-XXXX must be moved to a 10 x 10-meter cell. Failure to provide these conditions may end in injury or death from SCP-XXXX or the rift.
There have been multiple incidents where SCP-XXXX has left personnel and class D in critical condition, piercing human skin with ease with its jaws. No deaths have occurred as of yet. Injuries include dismemberment, deep gashes, and near-fatal blood loss. One of the most serious of these incidents involved a punctured skull. For one incident see addendum 1A.
Predatorial instincts kick in when brought prey, ripping animals apart with its front teeth. However, when panthers were brought into it's cell, the entity reacted playfully.
The entity was found roaming a local park in the UK seemingly opening up some kind of rift in the ground. The exact geographical location of this rift was on a rocky hill with minerals within and gelatinous indigo substance. It is thought that the minerals contained within the hill may be connected to SCP-XXXX. When summoning the rift a dark glow surrounded the entity. Research has shown that the rift is home to many different organisms. With the whole area quarantined, the rift was closed. A team of researchers has been assigned including Dr.Drakof, Dr.████████ and ████ to research this anomaly. SCP-XXXX caused a massive energy displacement and the foundation has sent in a cleanup team alongside a researcher. Bystanders have had this event wiped from their memory via amnestics. Once more is learned about the rift the foundation plans on possibly creating a faster mode of transport. In the future, the foundation is thinking of changing SCP-XXXX's object class based on its ability to create rifts.
UPDATE: SCP-XXXX HAS BEEN ABLE TO OPEN A RIFT. INFORMATION IS CLASSIFIED. [REDACTED] HAS BEEN FOUND INSIDE [REDACTED] INFORMATION AWAITING DECLASSIFICATION.
Addendum 1A
Two class Ds enter the chamber.
Class D5231: "This one's actually kinda cute."
Class D5232 walks up to SCP-XXXX
Class D5232: "Not cute. Just stupid. In fact, I bet that I can-"
SCP-XXXX opens its jaws and launches itself at Class D5232
Class D5232: "Goddammit get it off me! Son of a-"
Due to extreme blood loss in the forehead Class D5232 faints.
Class D5231: "Let me out!!!"
SCP-XXXX prepares to attack class D1

Addendum 1B
Dr. ████████ enters SCP-XXXX's chamber in a hazmat suit
Dr. ████████: "Open the rift."
SCP-XXXX seems to understand
A dark glow surrounds the room
Dr. ████████: "What are the energy readings?"
SCP-XXXX passes out
Dark glow fades
Dr. ████████: Dammit!"
Dr. ████████: "████ Open the chamber door."
████: Nods and opens the door
<end log>
Memo-
The experiment failed. However, SCP-XXXX did partly open the rift which gives us reason to believe we will have access to the rift in the future. -Dr.████████
