Niki went into pure battle mode.
She no longer saw the thousand foot tall Mother Naturia as a threat but as a target.
Niki had Janet rise up the side of Mother Naturia, peppering her with blasts the entire way, and dodging, ever dodging.
Mother Naturia grabbed at Janet, but it was no good. Niki easily evaded her.
When Niki got to Mother Naturia's abdomen, she made Janet go vertical so that she could use that whole bottom blast thing to let Mother Naturia have it right through the heart.
WAAAZZZZZZ!
"Aaaaggghhhh!"
Niki ran Janet into the hole she'd just made, as if planning to fly right through Mother Naturia.
The hole closed as fast as a clenching fist...
trapping Janet at the center of colossus Mother Naturia.
Well, not exactly trapped.
It was what Niki had planned.
Mother Naturia's plan seemed to be to crush Janet the way she had the Valid's van, but Janet was much bigger and tougher than that. Still, if Mother Naturia exerted enough pressure...
"Give her another blast," Niki told Janet. "See if you can spin. How long do you think you'd be able to keep the blaster going?"
"Forty-two seconds, roughly."
"That should be more than enough time. Ready?"
"On your signal."
"Go."
WAAAZZZZZZ!
"Aaarrggh!"
Mother Naturia dissolved as she collapsed.
