-Cell is visibly pained by the Thundaga but doesn't seem too overly phazed by it-
"Well, this has been fun, but..."
-Vanishes once more, Quick Moving high above the arena-
"I see no reason to keep this secondary arena around! The real tournament is happening back in my original ring! That being said, time for some demolition! Kame...hame..."
-Cell is aiming straight at the ring-
"HAAAAAAAAA!"
-Cell fires his Kamehameha straight down, hitting the arena dead-center and producing an immense explosion that, while it doesn't hit the room, does endanger the lives of anyone standing near the arena-
-He didn't blow up the planet but y'all might wanna haul ass away from there-
-When the flash from the Kamehameha subsides, Cell is long gone-

....Eh?
...Oh, that? Don't worry about that, I'm taking you with me!
