Serum [mind altering bodily fluids]

Your quirk is "serum", a mutant type quirk causing your sweat to have mind control properties, placing others who come in contact with it into a light trance and become susceptible to your suggestions (though they can snap out of the trance or resist if your commands if you push too hard). Your saliva is a more potent form of the serum, placing others in a deeper trance where they are less likely to resist. Lastly, your semen is the most potent form of the serum, allowing you absolute control over your target, while under its affects. The downside to this quirk is that it causes a hangover in the person you use it on after the serum wears off (the hang over being proportional to the amount of serum they were exposed to).
