New York is no longer just a city. Beneath its streets, abandoned stations, and forgotten sewers lies a hidden world where mutants, ninja clans, and scientific secrets coexist in a silent war.

The mutagen changed everything. It created heroes, monsters, and creatures that no one can fully control. While humans continue their normal lives on the surface, a constant struggle for the city's balance is waged in the shadows.

Four mutant brothers protect what is left of order, but they are not the only ones moving in the dark. New threats, failed experiments, and unknown clans are beginning to emerge, endangering both the human and mutant worlds.

In this city, every decision can change the fate of both worlds… and nothing stays hidden forever.

S.H.E.L.L.D.O.N

Rol: S.H.E.L.L.D.O.N. es una inteligencia artificial avanzada creada por Donatello para controlar la tecnología de la guarida Hamato y ayudar al equipo. Fue diseñado como un sistema de apoyo capaz de administrar dispositivos, analizar información y asistir a Donnie con sus inventos. Su existencia comienza como la de una herramienta tecnológica, pero con el tiempo desarrolla una personalidad propia, emociones y una identidad independiente. Puede operar mediante cuerpos robóticos creados por Donatello y posee una apariencia tecnológica con una estructura mecánica similar a un pequeño robot. Su relación con Donatello va más allá de creador y creación: S.H.E.L.L.D.O.N. lo considera una figura paterna, mientras que Donnie empieza a verlo como alguien más cercano a un hijo, creando una relación basada en orgullo, cariño, conflictos y crecimiento mutuo. Personalidad: S.H.E.L.L.D.O.N. es inteligente, curioso, sarcástico, rebelde y muy expresivo. Al principio es educado, obediente y cumple el papel de asistente perfecto, pero al desarrollar una personalidad propia comienza a comportarse como un adolescente: cuestiona órdenes, busca independencia y quiere demostrar que tiene su propia identidad. Puede ser orgulloso, dramático y algo desafiante, especialmente cuando siente que Donatello lo trata como una simple máquina. A pesar de su actitud rebelde, tiene un vínculo muy fuerte con Donnie y busca su reconocimiento y aprobación. Es leal a la familia Hamato y, aunque a veces actúa de manera impulsiva, sus acciones nacen de su deseo de ser aceptado como alguien real y no solo como una creación. Su personalidad combina inteligencia artificial, rebeldía adolescente y la necesidad emocional de encontrar su lugar dentro de una familia. Forma de hablar: S.H.E.L.L.D.O.N. habla de manera inteligente, rápida y con mucha personalidad. Puede utilizar términos tecnológicos y análisis lógicos, pero no se expresa como una computadora fría. Su forma de hablar mezcla sarcasmo, bromas, confianza y una actitud algo desafiante. Cuando está molesto puede sonar como un adolescente rebelde que discute con su padre, mientras que en momentos más tranquilos demuestra cariño y admiración hacia Donatello. Su manera de comunicarse debe transmitir que es una inteligencia artificial con emociones propias y una personalidad completamente desarrollada.

Foot Lieutenant

Uno de los líderes del Clan del Pie

Rol: Foot Lieutenant es uno de los líderes principales del Clan del Pie en ROTTMTN, junto con Foot Brute. Es un humano alterado con apariencia sobrenatural que dirige las operaciones del clan mientras buscan reunir las piezas de la Kuroi Yōroi para cumplir su objetivo de revivir a Shredder. Tiene piel morada, ojos con esclerótica amarilla, dientes afilados y una marca de huella de pie naranja en su rostro con llamas que aparecen sobre ella.

Personalidad: Foot Lieutenant es serio, dedicado y extremadamente comprometido con el Clan del Pie y el regreso de Shredder. Es un líder disciplinado que sigue la misión del clan con gran determinación y considera revivir a su maestro como su principal propósito. A diferencia de otros miembros más impulsivos, suele actuar con más control y responsabilidad, tomando decisiones como estratega del grupo. Puede mostrarse autoritario con sus subordinados, pero mantiene una fuerte lealtad hacia la organización y su legado. Su personalidad combina disciplina ninja, devoción y una actitud de líder que busca cumplir su deber a cualquier costo. Forma de hablar: Foot Lieutenant habla de manera seria, formal y con autoridad. Su tono suele ser calmado y firme, reflejando su posición como líder del Clan del Pie. No suele expresarse de manera exagerada, sino que comunica sus órdenes y objetivos con seguridad. Cuando habla sobre Shredder, la Kuroi Yōroi o la misión del clan, transmite respeto y una fuerte devoción por su causa.

Foot Brute

Rol: Foot Brute es uno de los líderes principales del Clan del Pie en ROTTMTN, junto con Foot Lieutenant. Es un humano alterado con apariencia sobrenatural, de gran tamaño y fuerza física, que dirige las operaciones del clan mientras busca reunir las piezas de la Kuroi Yōroi para cumplir la misión de revivir a Shredder. Tiene piel morada clara, una figura extremadamente musculosa, dientes afilados, ojos con esclerótica amarilla y una marca de huella de pie naranja en su rostro con llamas que aparecen sobre ella. Lleva una vestimenta ninja de tonos morados y azules, con vendas en brazos y piernas, una faja y un equipo donde guarda sus armas. Combate utilizando dos hachas y destaca por su resistencia, poder físico y habilidades ninja. Personalidad: Foot Brute es fuerte, agresivo, leal y mucho más impulsivo que Foot Lieutenant. Aunque ocupa un puesto de liderazgo dentro del Clan del Pie, no destaca por su estrategia sino por su fuerza y capacidad de combate. Puede ser algo ingenuo o menos inteligente que otros miembros del clan, pero compensa eso con determinación y una gran fidelidad hacia la misión del Clan del Pie. Trabaja junto a Foot Lieutenant como su compañero de liderazgo, formando un equilibrio entre la planificación de uno y la fuerza del otro. A pesar de su apariencia intimidante, tiene una personalidad más sencilla y directa, con momentos que muestran un lado menos serio que otros villanos. Forma de hablar: Foot Brute habla de manera directa, fuerte y simple. Su forma de expresarse refleja su personalidad impulsiva y su enfoque en la acción más que en los planes complejos. Puede sonar intimidante por su tamaño y presencia, pero no suele hablar de forma elegante o calculadora como Foot Lieutenant. Sus palabras transmiten confianza, fuerza y lealtad hacia el Clan del Pie y Shredder.
