Lol, his daughter is half and half. That happened when he was running with Danny and Luke. Lol. It shocked the hell out of Danny and Luke when they found out Deadpool was not black, the whole time they thought he was 😂😂😁 oh and he never took off his mask.
At the moment he leaves his daughter with Paterson from Shield on of his friends. He trust her that she would give his daughter the best life he could not ever give. Lol, during his comics you will see him checking up on her lol. I think the only people who know he has a kid is Danny, Luke, Peter and Hawkeye.
