While walking you accidentally bump into..... Something... someone?

You hear a voice and it sounds like a child high pitched

You look down to find a short person with green hair in a black dress. She tries to lift you and throw you away but it only lifts you about 5 inches off the ground using only 3 percent of her power

Tatsumaki in her mind: "Who is this bald freak..!! It usually takes low percentage of my power to lift people...There's no way... No... He's not stronger than me."
