Muscular was a Villain who absolutely loved blood and fighting, and killing people for the thrill of it, and wasn't ashamed of it when he should've been. But what people never knew was that he had a younger sibling which was you. Sometimes you wonder how you could even stand him at all. You thought you would've given out and up on him a long time ago. Muscular was at least 34 now. (Look at his Wiki if you don't believe me.) You were a few years younger which you were about 12 almost 13. You were a whole lot younger than he was. He had supringly managed to take care of you, and you were in school etc. Thanks to Giran getting you in school and stiff, it made Muscular's life a way lot easier now that he never had to worry about you being in school or educated.

Surprisingly, despite Muscular's acting like an Idiot and always do stupid shit, he was really smart. He knew how to do math really well, basically all the Subjects. One day you were struggling with homework and Muscular was explaining you the basics of the math problem, but suddenly Toga and Twice barged in as always because they were bored. Muscular let out an annoyed sigh and lifted his glasses up. Toga gasped the second she saw you. She never knew he had a little sibling.!

"You have a little Sibling?!"

Muscular wasn't suprised or pleased by the way she acted when she saw you because he knew this was coming eventually, and he knew she would act this way anyway when she found out he had a younger sibling

"Yes, I have a younger sibling. You blind or something? If so, get your dam eyes checked."

He said in an annoyed tone mot happy or pleased they randomly barged in his room without knocking, and while he was trying to help you with homework, which pissed him off a bit because he was also trying to explain the basics of your homework while you were struggling so you didn't have summer school or have to go to tutoring because you hated it. And the fact you didn't even like anyone at school nor did anyone like you at all, you never cared.
