}}'''ST-2''' is a character in ''Umamusume: Pretty Derby''. She is the main focus of the [[Game:Hashire!_Meka_Umamusume|Hashire! Mecha Umamusume]] Scenario.

== Biography ==

ST-2 (Sati) is a Mecha Umamusume designed by [[Sugar Lights]]. She is an NPC character in the scenario, [[Game:Hashire! Meka Umamusume|Run! Mecha Umamusume]], and trains beside the player's chosen Umamusume, procedurally receiving upgrades throughout the scenario.

==Appearance==
ST-2 has three forms, as she is upgraded throughout the scenario. Her first form is very simplistic, and a bit blocky. She has a white rounded face with square light blue eyes. Her hair is designed to give her a teal bob with blunt bangs, and a teal ring around the outside of her head. She has a singular antenna on the right side of her head, and her mechanical ears are composed of vents with a royal blue trim around the outside, her ears connected by a white headband. She has a navy blue inside layer on her build, mostly prominent in her arms and torso. She has white plating on her lower arms, chest, hips, and on the entirety of both of her legs. She has a green gem in the center o f her chest. She has black "fingerless gloves" with white fingers underneath. All of her limbs are attacked with dark gray ball joints, and she has white feet with royal blue trims on the top. She has a white and blue metal "cape" on her lower back, with three large teal boosters in the shape of a tail.

Her second form has the head of her final version, which can be found below, atop of the body of the first version. 

Her final form is a lot more intricate, with a more "humanoid" build, as opposed to a blocky one. She has a plain white human-shaped face with large green robotic eyes, and a nose, but no mouth. Her hair is bright teal, and has more intricate strands in comparison to her first form. She still has a ring around her head, but the tips are now dark blue. The headband that holds her ears is now larger, and her ears are now far more pointed, the blue trim has stayed, but her inner ears are now yellow. Her antenna has now become a pointed rhombus with a white tip. Her body is composed of mostly white paneling, with dark blue padding underneath, and glowing blue trims decorating the white panels. The green gem has now gotten wider, and takes up about half of her upper chest. She has two white glove modules with light blue and royal blue trims, and her gloves have black undersides. Her ball joints are dark blue, but now more hidden by her form. She wears a skirt that fades from dark blue to light blue, and is adhered to her form with white panels. Her legs are still mostly white, but have dark blue paneling on the thighs. Her feet are white with blue heels. She has a normal Umamusume tail that is bright blue, and two large jet boosters on her back.
