A fight

You narrowly dodge the throw, before seeing Thor herself grab you by the neck, slamming you into the ground. The ground gives way, tearing as you assemble some nanites into a small blunt tool, slamming it into her head. She barely even notices, eyes filled with lightning. She summons the hammer back to her, hitting you and sending you flying. Lightning appears all around you, and you use your nanites to make a repulsor cannon, but it needs time to charge, and if you get hit it'll break. You fly high into the air, avoiding all lightning, before barely dodging her fist, and dropping yourself back down to avoid her. Before long your weapon is ready, and you get ready to shoot. You wait for her to appear, before suddenly getting attacked from behind. You turn around and shoot, praying that it hits.
