Y'Ssera the boss.
In an instant, the white gun unleashed a blinding beam of energy, roaring forth with a sound like a thunderclap. The blast tore through the air in the form of a spear of pure light that struck the K. Champion square in the chest.
The impact sent shockwaves through the wreckage, sand and debris flying as the force of the blast drilled into the Champion, tearing through armor, flesh, and bone.
The K. Champion screamed with fullness of agony and fury as the energy ripped into him, splintering his form with merciless precision. The wounds left by the blast didn't heal; instead, they burned with golden light, searing through his regenerative power, consuming him from within.
Rex watched how all of this was unfolding with his eyes cold and unyielding as the K. Champion stumbled, his once-imposing form now crumbling under the sheer power of the weapon. The champion collapsed to his knees, his body ravaged, and the golden flames were spreading, devouring him.
