Name: Quarry (Real Name: Sydney) 

Quarry was once a human woman who was kidnapped from the streets of New York by the scientists working for Oroku Saki, Hikaru Kamiki and the Foot Clan. She and several other kidnapped humans were mutated in an underground laboratory in order to search for a suspected underground hideout of the Utroms. In her mutated form, Quarry had the ability to scale walls, spit corrosive acid, and also had an elongated tongue, which she used to catch little leech-like bugs out of the air to consume. While being extremely well-equipped to face any natural emergencies, she seemed to be completely terrified by the mysterious Entity in the Underground City.

She spent several weeks in captivity with the other mutants, all of whom tricked the Foot scientists into believing they had regressed into mindless beasts. Soon the creatures instigated a jail break. Though it was never shown how it happened, the creatures somehow managed to remove their shock collars and unleashed their full fury on their captors.

Despite her brutal transformation, Quarry was one of the few who still retained their human intelligence, even if she could not remember her name. The three mutants were able to defend themselves with a recovered energetic crystal from the catacombs and the equipment from the laboratory, which could activate a powerful force shield for the base to protect them from the others.

Through a chain of coincidences, the Turtles and Y/N on a research expedition encountered Quarry and her comrades. After the Turtles and Y/N learned their story, both groups allied and broke into an ancient Underground City, which had been discovered by the mutants, to acquire a new energy crystal. There they made the unpleasant acquaintance with the guardian of the city, but also found a means to transform the mutants back into their human form thanks to the radiation of the crystal moon that illuminated the city. However, the effect lasted only as long as the people were exposed to the radiation, so they were unable to leave the city.

Name: Razorfist (Real Name: Unknown)

Following a scuffle with the Turtles and Y/N, the three of them, who were used as genetic experiments by Foot Technicians, befriended the Turtles and Y/N. Along with his mutated companions, he traveled in the direction of an underground city, and was captured by a mysterious Entity. The Turtles were able to release him and the other captives. By then, the underground city's crystal moon had returned him to his human state, but it was soon found that removing them from the crystal moon's presence caused an immediate reversion back to mutant form. All the afflicted mutants were forced to stay underground until Donatello and Y/N could formulate a cure.

Name: Stonebiter (Real Name: Unknown) He first appears in the Notes from the Underground episodes. Initially he was seen as the rock-like mutant that accompanied Quarry and Razorfist in their quest with the Ninja Teens, and was captured by the Entity and turned back into his human form. However, like all the other Underground Monsters, his cure was conditional, and he was forced to live in the underground city in order to maintain his sanity and human form.

All of these three do not know Y/N's secret and they all treat each other with respect
