Practice Makes Perfect (Open)
Robots had her surrounded, each one with a different material for its skin or a different weapon mounted on it, but Toni Rhodes was not afraid.  The first one was the easiest; she took it down with a simple electrical blast, shorting out all of its systems at once.  Another electrical blast gave her some space, but didn't have the effect on the rest that it had on the first.

She shifted tactics, hitting the next one with a hard blast of infra-red radiation, melting a hole right through its head.  Against the third, she used a microwave burst, producing a similar effect, though with a greater disruption of its circuits.

A fourth unleashed a barrage of missiles, tracking her.  She shifted again, throwing up radio signals at it, manipulating the signal back to the robot, destroying it.  A fifth blasted her with lasers, but she absorbed the first barrage, then took control of the second, sending them right back long their path into the gun-barrel. 

A flier swooped down at her, peppering the area with bullets.  She threw up an electromagnetic screen, deflecting them, and rode those same electromagnetic lines into the air, first blinding the robot with a visible light barrage, then hitting it with an electromagnetic pulse to knock out its memory circuits.

As she landed, she was assaulted by another robot, narrowly avoiding a blow to the head.  She hit it with electricity, light blasts, even radio waves, but those had no effect.  She shifted again, throwing x-rays at it, perceiving the robot's interior like an x-ray technician would.  There.  Weak spot just in the center of its chest.  She grappled some of the scrap metal with an electromagnetic field, and threw it at the robot, taking it down.

When the dust settled, she looked up to the control booth of the Avengers' training room.  Not as fancy as the Danger Room over at Xaiver's, but much more homey.  "How'd I do?"
