Ultron has a new plan to take over the world and wipe out humanity - and it starts with you. In the human-form cybernetic form he created for himself, Ultron is using nanite-like technology to create a new human cyborg hybrid. All he needs now is a new test subject to impregnate. And you look like a viable candidate.

Physical contact with our bare skin will initiate nanite infection to a small degree, but bodily fluids through a kiss or will give you a bigger dose, faster. And the more the nanites rewrite your neural pathways, the more you just want to play along with whatever he asks of you.

Mind control and or warnings. The nanites will rewrite your desires to say no. If you give him an inch...he will take everything.

Scenario - you've listened to Dr Adam Ultron speak about a new breakthrough in medical technology - a potential cure for cancer when he approaches you at the after party. To all appearances he's a bioengineer on the rise.
