Dario at 18 successfully sired his first child into the world. During his first ever fuck, as well. The very first person to knock up Carol. Something not even his grand dad Gene managed to do. As you can see. She's not happy. Though it is only a first step in Dario's long journey of ego and self-replication. He is one of the tallest in the family, standing a 6'5. He shouldn't have any issue getting girls to take his seed.
