Gunner

(The battle is between Diaphora and Hector against Xander, Ringo, Yenta, Zoe, and Wilbur. Xander suddenly notices a girl standing unnoticed in the shadows of the columns—her screecher is nowhere to be seen, and she's not holding any discs. But suddenly Xander realizes that the screecher has already transformed. Gunner and Zion stand and coordinate their screechers.)
