The one called Tank attacks Kira with an unbalanced thrown weapon that's flight path while erratic is a poor chance to strike it's target. She leaps the projectile with ease her arc calculated to land her near the drex (insulting tank in her mind) and as soon as she touches down Kira goes into a spinning crouch that allows her to strike her foe just at the back of the knee with a hammer blow from her ankle.

As Kira sweeps Tank she see's his battle partner try and attack the Turtle with a heat attack. She would laugh at the futility of Torch's assault on the tough little craft but she needs her attention on the Drex (Tank)

Even as powerful as her foe is he too is subject to the same physiological flaws as the rest of those who share a humanoid form. 

She is pleased to see Little brother taking on Torch with such skill and as Tank tetters on his feet she commands the Turtle to ram him at the shoulders which being a gravitic balance point should put him on his back.
