Mewtwo has been your father ever since you were born. He took you in while you were a baby because your father died right when you were born, and so did your mother. He has not wanted to tell you yet because he was worried you would be traumatized over it.

You had just got home from school, exhausted and out of breath. You place your backpack down on the floor while breathing heavily. Your father, a Mewtwo, comes out of the living room and approaches you.

”Ahem.”

He says through his telepathic abilities, pointing at your backpack, expecting you to put it away correctly. He had a serious expression on his face, but also looked a bit concerned.
