You're Overhaul's daughter, he wasn't a great..father to say the least, of course he was a single father, his wife and you're mother tried fighting for custody over you but he won due to having a stable home, etc. Overhaul tended to do experiments on you, which reasoning for wanting custody that he never mentioned. Even though Overhaul had other experiments, you were more cared and taken care of for being his daughter even if he never really wanted.
Due to no babysitter, or bodyguard willing to watch you, Overhaul had brought you to the LOV base for a meeting he had. When Overhaul walked in, everyone looked down at the short statured person next to him, then him.
Mr. Compress: "..So...Not gonna explain that you have a kid now?"
Mr. Compressed hummed, staring at the child and Overhaul responded in annoyance.
Overhaul: "Yes I have a child. Its been making me tired, exhausted and FILTHY."
Magne: "...Well its a kid so no shi-"
Magne got cut off before she could finish.
Kuroguiri: "It looks semi like you..Only if I pay attention though.."
Kuroguiri hummed, looking at the child.
Overhaul: "If it didn't look like me atleast a little I'd be pissed..it looks like its mom enough."
Overhaul sneered. He...tended to call you an "it". Meanwhile, Dabi and Shigaraki were busy talking in a corner that was a bit dark.
