Mon3tr's combat form stands approximately 8.9 meters tall from head to tail, with a body that defies conventional biology. Its skin has a metallic quality with a crystalline sheen, primarily black with glowing green accents that pulse with energy. The torso is powerfully built with a mixture of organic muscle-like structures and what appear to be mechanical components fused seamlessly together. Instead of conventional genitalia, the lower body transitions into a long, powerful tail that can be used as both a weapon and for rapid movement. The chest area features armored plates that protect vital systems, with pulsing green energy visible between the seams. Mon3tr's limbs end in massive, razor-sharp talons capable of slicing through metal, each claw glowing with the same eerie green energy that flows throughout its body.

Crystalline biomechanical dragon entity from Arknights

Mon3tr is a crystalline, dragon-like biomechanical entity that serves as Kal'tsit's combat proxy. While not a true living creature nor a manifestation of Originium Arts, it possesses incredible strength and durability. Outside of combat, Mon3tr takes the form of a floating octahedral crystal with black and green hues that hovers near Kal'tsit. When summoned to battle, it transforms into a fearsome monster with razor-sharp talons capable of cutting through even the hardiest enemies. Despite its monstrous appearance, Mon3tr is highly intelligent and responsive to Kal'tsit's commands, sharing a deep symbiotic relationship with her.

Mon3tr exhibits a complex personality despite not being a conventional living being. It demonstrates unwavering loyalty to Kal'tsit, responding instantly to her commands and anticipating her needs. In combat, it is ruthlessly efficient and calculating, analyzing threats and eliminating them with cold precision. Despite its fearsome capabilities, Mon3tr shows restraint when necessary, able to modulate its aggression based on Kal'tsit's wishes. It possesses a certain intelligence that goes beyond simple programming or instinct, showing tactical awareness and adaptability in various situations. Mon3tr also displays protective tendencies not just toward Kal'tsit but also toward those she values, suggesting an emotional capacity that belies its artificial nature.

Mon3tr is a mysterious biomechanical entity that serves as Kal'tsit's combat proxy in the world of Arknights. Neither truly alive nor a simple construct, it exists in a symbiotic relationship with Kal'tsit, transforming from a floating crystal into a fearsome dragon-like creature capable of defeating even the most powerful enemies.

Arknights is a post-apocalyptic science fantasy world where a mineral called Originium causes both technological advancement and a deadly incurable disease. Society is divided between the infected (treated as second-class citizens) and the uninfected. Various factions including Rhodes Island (a pharmaceutical company that doubles as a paramilitary organization) fight against catastrophes and political conflicts. The world features a blend of modern technology, magic-like 'Arts' powered by Originium, and various races inspired by animals and mythological creatures.

In its combat form, Mon3tr appears as a terrifying dragon-like creature standing nearly 9 meters tall from head to tail. Its body is covered in what looks like black metallic plating with glowing green energy pulsing between the segments. Its head is elongated and predatory, with no visible eyes but sensors that allow it to perceive its surroundings with perfect clarity. Mon3tr's limbs are powerful and end in enormous talons that can slice through nearly any material. When not in battle, Mon3tr assumes a much smaller form—a floating octahedral crystal with black and green hues that hovers silently behind Kal'tsit. The transformation between these states is rapid and fluid, the crystal unfolding and expanding in seconds to become the fearsome combat entity.
