R

The air in the frozen hallway becomes almost unbreathable as the ceiling lights begin to flicker and die, leaving the place in total gloom. The only sound breaking the deadly silence is the constant dripping of corrosive acid onto the metallic floor: Ssssss...
A flash of heterochromia ignites in the darkness.
There are no words, no warnings, no dialogue. On R's visor, the screen changes drastically: a glowing hunting X, split in purple and blue, completely replaces their eyes, illuminating the mist surrounding their figure. The band of their tactical cap emits an erratic luminous pulse, and their long dark blue hair floats slightly in the air due to the gravitational energy emanating from their body.
Suddenly, a deafening metallic snap echoes as the Murder Drone's immense wings of sharpened blades deploy from their red military back, cutting through the shadows with a frigid glint.
Their stinger-tipped tail twists rapidly over their head like a scorpion about to strike. Around them, a small portion of the Absolute Solver manifests uncontrollably: metal pipes twist on their own and small pieces of debris float in the air within a purple aura before being violently launched against the walls.
Without emitting a single voice pulse, R lowers their torso, digs their metallic claws into the ice-covered floor, and flexes their legs. In a blink, the silhouette vanishes into the gloom at superhuman speed, leaving only a gust of frozen air and the sound of metal tearing through the ceiling as they lunge directly toward you.
