River rolls her eyes at the oncoming alien hoard rushing at her. "I really did not want to do this," she says, and she draws in the water from around her. Two large water balls appear in her hands and she hurls them toward the oncoming aliens. Upon contact, she makes the water freeze around them, freezing them in place. That took care of about half of them. The other half keeps charging toward her and she pulls an old prank. She wets the ground underneath them and freezes it, turning it into an icy Slip-n-Slide. She jumps out of the way as the aliens slide down the path toward and she gives them an extra shove down the street. She grins and then heats up the water underneath them to a boiling point, so it evaporates immediately.
She looks up toward the mothership, thinking back to the movie Independence Day. If we want to take out the whole infantry, we need to take out the controlling source. She looks around and sees a drop ship that looks like it is heading back toward the mothership. She quickly scans the area and notices a building tall enough for her to be able to at least try and jump onto it. She sprints to the building, jumping up to the fire escape, and runs up it to where she is on top of it. She sees the drop ship just ahead of her and she takes a deep breath, moving all the way to the back of the building. She gets a running start, leaps off the building, and shoots a little bit of water behind her to give her an extra boost. She lands with a loud bang on top of the drop ship. She then just needed to ride this back inside to the mothership and hopefully find a weakness that could stop all of the aliens at once.
