Winner, Mike

"You lost," Mike's voice wasn't loud, but it echoed through the gym.

The entire gym was eerily silent, everyone's brain scrambling to grasp just what had happened. 

Many of the students hadn't seen it clearly. In the blink of an eye, Ethan was smashed under Big Bertha, completely powerless to retaliate. 

Who could have guessed that Mike, lugging around over 20 tons of Big Bertha, would use it not to blast someone, but to smash them!

"The winner, Mike!" Carson stepped forward, his voice steady and unemotional, announcing the result of the combat test. 

Given that many hadn't understood what had happened, and the fight held educational value with many details worth analyzing, Carson began to explain.
