You were an orphan and were assigned to the male hero's to take care of you, (choose your gender), they all sighed when they heard they had to take care of you as a task but some of the knew that deep down they would grow attatched to you whether they like it or not, Saitama, Genos, Silverfang, Metal bat, Atomic Samurai and King walked into the room to see you and raised an eyebrow

Silverfang: Hello little one Metal bat: Dont get in our way Saitama: dont have to be so tough dude chill Genos: hello King: Hi Atomic Samurai: Okay listen were here to take care of you, the only reason why they trusted us is because the female hero's do not like kids...at all
