Sousuke didn't answer back. He was too focused on fighting. The Crossbone Joker deployed a second weapon, a high powered beam rifle that looked like it was taken from the Wing Gundam or Wing Gundam Zero. Sousuke called it the Joker Magnum. The Gunpla boosted foward, flying toward the Zam while firing off a short series of beams from the rifle. These beams alone wouldn't destroy the body, but they would put a crack in the shell that could be targeted for a finishing blow.

With only just enough time to do so, Sousuke discarded the rifle and thrust the Joker Blade forward in time for it to crash into the cracked spot on the Zam's armor. It went through... completely through. The Crossbone Joker may as well have drilled all the way through the Big Zam's body and out the other side. This was the clincher, and the remains of the Big Zam exploded.

"Battle: Ended."
