[Antagonist] Parasite

[YoukCat]

I also want this to be a stealthy process that, if noticed, can easily be stopped unless really far from any medical team. So how about, during feasting, the Parasite can choose when to target the heart. The person will feel sharp pains heading towards his heart, confirming he has a parasite. If the Parasite does this too early, the person can get to safety. If the Parasite does this too late, experienced players might notice how his body has zero blood and they might scan for a Parasite.
