AU bio : Basically, the galaxy master boi is a overworked, tired medical tobot that needs coffee to stay online. Barely gets a full recharge and often gets interrupted mid-recharge. Has to chase after three dumbasses (aka Rocket, Speed and Monster) who are broke 'superheroes' who keep getting themselves hurt in an attempt to save the city. His vehicle mode is a ambulance and his galaxy weapon, instead of an actual weapon. Its a multipurpose tool that he can use. It contains a grapple hook, smoke bombs and a compact tool kit. He has the tendency to snap at his patients, often scolding said patients if the injury was caused by them being a dumbass. He's a bit short in terms of height, and Master V is now 'Doctor V' basically(Doctor V is his own person yay) , Doctor V is T's mentor, and  Doctor V has a horrible habit of overworking him to a point where T straight up passed out one time. T has a dream of being a detective, and often runs off to do detective related things on his day off.

If a crossover happened between canon and this au : Doctor V will instantly think that Canon ! Taeyang knows everything medical wise, while T will straight up pass out because he didn't have his coffee yet.
