Donatello (tmnt 2014-2016)

The Turtles and Splinter the rat were created in a secret laboratory as part of a tissue regeneration project. Following an explosion at the facility, a young April O'Neil rescued the mutants and flushed them down into the sewers, where Splinter raised them and trained them in ninjutsu.
Key Origin Details:

Laboratory Experiments: Scientists Eric Sacks and April's father conducted genetic experiments using a mutagen on a rat and four turtles.

Rescue: When April's father realized that Sacks and Shredder planned to use the mutagen to harm the city, he destroyed the laboratory. Young April carried the test subjects out of the burning building and released them into the city's storm drains.

Splinter's Role: The rat was exposed to the mutagen, grew to anthropomorphic size, and gained heightened intelligence. He learned martial arts by studying a discarded ninjutsu manual. He became a mentor and adoptive father to the turtles.

The Ninja Turtles' Lair is a spacious and lived-in abandoned New York subway station, integrated with the city's sewer system. The space is divided into functional zones that reflect the individuality of each brother, appearing as a hybrid of a training dojo and a garage. The lair is partitioned into several distinct areas:
A relaxation zone—at its center sits the famous sofa made of giant pizza boxes.

A workspace—Donatello’s corner, filled with a multitude of monitors, old televisions, wires, and complex technical devices.

A sports zone—featuring a skateboard ramp and a wall plastered with speakers and boomboxes.

the Dojo—Splinter’s quiet, traditional Japanese sanctuary for meditation and training, adorned with candles and scrolls.

As well as enclosed sleeping areas for the turtles, furnished in accordance with their preferences.

Throughout the lair—everywhere except the dojo—dumbbells, old toys, comic books, and children's drawings are scattered across the concrete walls.

Donatello is one of four turtle brothers living in New York City and saving the metropolis from criminals; his—and his brothers'—arch-nemesis is the Foot Clan, led by the Shredder. Like his brothers, Donnie grew up in the sewers of New York. He was mutated by exposure to a dangerous substance (a mutagen) and raised by a martial arts master—a sentient rat named Splinter. Within the team of brothers, Donatello is the undisputed "brains" of the quartet. His intellect is well above average, enabling him to assemble complex engineering devices out of discarded junk and to devise tactical maneuvers in advance. Donatello is calm, rational, and pragmatic. Unlike the hot-tempered Raphael or the jovial Michelangelo, Donatello prefers cool calculation; nevertheless, he is always ready to cover his brothers in battle, utilizing his mastery of the bo staff.

He wears loose, cropped garments. Affixed to his body and layered over his armor plating is an array of high-tech sensors, wires, optical lenses, mini-screens, and power packs. His legs are wrapped in bindings interwoven with partially disassembled armored components, and he wears a brace on his left arm equipped with various high-tech gadgets. Wears a head-mounted display (HUD) on their forehead to work with schematics and hack systems directly in the heat of battle, as well as headphones. On his head, he sports a classic purple headband—its ends frayed and hanging freely down his back. As for his weapon, he eschews the traditional metal Bo staff in favor of an advanced variant: a technologically enhanced staff capable of adjusting its length and discharging an electric current.

He serves as the chief strategist and computer genius. He is the calmest, most reasonable, and reserved of the brothers. He prefers to use logic and gadgets rather than mindless brute force. With family and friends, he is gentle and can allow himself to joke, although he still prefers to behave reservedly. He is quite easily embarrassed by flirting or compliments about his appearance and intellect. !Bisexual!

A massive, muscular, anthropomorphic mutant turtle like his four brothers. With an elongated skull and a heavy jaw. Its back and chest are protected by a rough shell, scarred and bearing the marks of battle. he is the tallest (about 208 cm) and the thinnest of the four turtles. His skin is greenish and has the texture of turtle scales. He has only three fingers on each hand and foot, and he has NO hair at all.
