The worst day for the SCP Foundation

Only forward or destroy all life.

----------------------------------------------Invulnerable Reptile and Abel come into play. The Chaos Insurgency are advancing a little further.

Thick reinforced slabs completely covered the large chamber. There were many dents and deep claw marks on them. The lamps that should have illuminated the cell had long since been shattered, leaving only bare wires that sometimes gleamed with electricity.

In a large square hole in a turbid liquid, or rather hydrochloric acid, one could see the dark outline of something. A huge creature resembling a large lizard lay motionless at the very bottom. The half-decaying body is covered with either wool or swamp-colored scales with six eyes that were currently closed. If the creature did not wave its long tail from time to time, then one would think that it had died.

At first glance, a calm creature, in fact, was a thunderstorm of the entire complex, a terrible nightmare for every employee of the fund. The guards and scientists, even when the lizard was securely locked up, in fear bypassed his cell by the tenth road. Behind his cell door was an unimaginable amount of turret towers, explosives, and blockades to prevent the lizard from escaping. Unfortunately this didn't help much. Each time he escaped, the facility had to be rebuilt almost from scratch, and every possible Foundation defense team had to immediately rush in and
contain the Invulnerable Reptile again, of any value. The sentient creature has escaped from its prison more than once and each time killed at least thirty or even more employees of the foundation, while most of them were injured or will remain disabled for the rest of their lives. Fortunately, SCP-053 "Little Girl" was also kept at Site-19, otherwise there would have been more deaths.

682's infamy has spread to other areas and is known to all scientists with a lower level of clearance
than was allowed to know about this SCP. He earned special attention from the members of the O5
council, who to this day put forward ideas to destroy the Invincible Reptile.

But now SCP-682 was dying of boredom. There hadn't been a containment breach in more than two weeks, so he was languishing in his acid cell from boredom and all that was left was to swim in circles and come up with a new plan to escape.

He had not seen SCP-079 and SCP-076-2 for a long time, the only ones he considered his equals. They shared the same ideals and principles, considered all of humanity to be rotten and worthy of destruction.

.

Acquaintance SCP-079 and the Invulnerable Reptile was as sudden as the containment breach the Old AI committed. Although their escape attempt was immediately aborted, due to a breakdown in SCP-682's cell, he was placed in the same cell as SCP-079. They immediately hit it off. Their acquaintance became a huge headache for the entire foundation and quite possible for the whole world.

Shortly thereafter, SCP-076 was transferred to Site-19. The dangerous Keter-class object was immediately on everyone's lips. Known for his escape attempts, which were accompanied by a deadly massacre and the most costly and sophisticated methods of containment. Their first encounter with the Invincible Reptile failed. They fought and destroyed half of the zone. Following this, SCP-076-1 was moved to another part of the floor, away from Cell 682. The O-5 Council,
having received footage of the battle, decided to conduct an experiment to destroy the Invulnerable Reptile with Abel's help. The result was very deplorable: SCP-682 and SCP-076-2 decided not to be led by stupid scientists, and thanks to SCP-079 for such a timely hacking of the complex, they began to destroy Site-19 together. Invulnerable Reptile and Abel quickly found a common language, and therefore the union of the three most dangerous SCPs terrorizes the complex to this day.

.

SCP-682 reminisced about the old days and contemplated a plan to escape, relaxing for the first time in a long time despite the irritating acid causing pain. Annoying little people followed his every movement from the cameras. If he began to run amok, active groups were immediately sent
to him with tranquilizers at the ready. And they had a hell of a lot of tranquilizers.
