This monstrosity was created from that one picture on the SCP memes Reddit crossing over SCP Foundation and Monster Musume. I never had more regrets until now.

Dr. Bright, or SCP-963, waltzed around Site-19. There was a lot of useful and quaint SCps here. I.e, the coffee machine, SCP 294. He found it peculiar that it could, theoretically, dispense any object in a liquid state. There was even a liquid capable of disintegrating the Impossible-to-Destroy Reptile. Shame that it was impossible to gather a large quantity of the solution. However, Dr. Bright had a bright idea.
What if, he found something that could turn the Keter-class into girls? That may sound insane, but it'll also help sell SCP body pillows, no doubt going to be a smashing success, but they may be neutralized. A brilliant idea!
He had presented his idea to his fellow researchers, but they laughed at him. Well, they can't get rid of him that easily. Heck, he doesn't even follow the list that they gave him. With a grin, he walked into the lounge and stopped right in front of the machine. WIth a quick input into the keyboard, it hummed before a pink liquid squirted out into the styrofoam cup. Hmm, so it doesn't affect inanimate objects, so he can't use it on SCP-173, but it should work on the others. Hopefully. Eh, it doesn't matter. He'll just grab a D-class. They're expendable.
This has to be done in secret. So, Dr. Bright will have to do it himself. He walked back into his office and grabbed his trusty newspaper, his sword, and shield against the terror known as SCP-692. It's here in Site 19 because of yet another testing with a Euclid. Meh. He saw the seven Guards standing with an arsenal of weapons-not like it'll do the anything-in front of the door leading to SCP-682. With a wave of his ID, the group stood to the side as he entered the observation room for 682. He strode up to the microphone stand and looked down at the acid pool below the glass screen.
"Hello, SCP-682." Dr. Bright called into the mic set. There was no response.
He tried again. "He- Gah!" the pool exploded with the force of a torpedo detonating as the monstrous entity surfaced from below.
He could hear the beast's guttural chortle at his shock. He opened the airlock leading to the room. This was where things could go badly, for the host.
Taking the small cup, he poured it onto the lunch meal for the SCP and activated the crane. He gently steered it so that the meal was just out of reach of 682 from within the pool so it would have to leave. Dead flesh doesn't seem to react to it, which would be fine by him. Just as the meat touched the floor and the hook was removed, he felt himself be tackled to the floor.
"Dr. Bright! Of all the most idiotic things, you have done. You do this!" Dr. Edison shouted while also having a certain gleam in his eyes. He was one of the fun scientists. Until the O5 council decided to say no to his mad-scientist-ing. The guards restrained Bright as the mad scientist seemed to skip to the glass window and peered down as SCP-682 walked over to the hunk of meat and seemed to stare at it in contemplation.
"What did you do, Bright?" he asked as he stared down.
"You remember what I mentioned about turning SCPs into girls?" Bright grinned as Dr. Edison started to laugh maniacally.
"You didn't" he breathlessly exclaimed as Dr. Kiryu came in and saw Dr. Bright pinned down and Dr. Edison laughing.
"Oh no. What have you two done?" she moaned as two new-faces peeked into the door and immediately backed away.
At that moment, the SCP ate the chunk of meat and sat there.
Dr. Edison stopped abruptly and looked down at the SCP in surprise.
"Nothing?" he took out a notepad and started to write down. "SCP-294-K was unable to transmute SCP-682."
"You did WHAT!" Dr. Kiryu screeched as she ran towards the glass window and looked down as the reptile seemed to shake and contort.
"Scratch that. It works splendidly and we can now make SCP porn!" he cries out in happiness as he runs out of the room. "The Department of Metafiction is going full speed ahead!"
Dr. Bright got out and brushed his lab coat as a black-haired girl (who was naked) appear where SCP-682 was previously shaking on. He could already see sores on the shivering girl starting to form from the toxic environment of the place.
"It worked!" he cackled as he swiftly took an environment suit and ran through the air lock as the doctor and the guards comprehended what they had just witnessed. He swiftly picked up who was formerly SCP-682 and dragged her out into the control center. "Lock down the control center door," he said as the guards nodded and the nearly 3-foot thick door made of a paranormal metal shuddered to a close.
