K9-Ball is a tech used in Chrono Cross. After acquiring 3 boss stars, Poshul learns this technique. Only she can learn it.
Description
Curling her body into a ball, Poshul launches herself at a single opponent, ricocheting off them with extreme force and speed. Yellow sparks erupt from the point of impact as she resumes her battle pose.
Etymology
K9 is a pun of canine, a word used for describing dogs, and Poshul is a dog. Ball is literally the shape she takes in this tech.
