Suddenly, without warning, a titanic explosion with a blast which roared like thunder shook the ground behind the group, leveling a few hills in the process. As Future Xenest and Future Brachi looked to see the source of it, their eyes widened in horror as the Hubrin Fortress they tried to defend was collapsing to the ground in sheets of flame... before spotting soldiers of Siber near it, having used the battle overall against Snow's grandfather as a chance to take the scenic route and place a sneak attack on the Hubrin Fortress.
"Excellent, the Earth-based creatures die in a pyre of their own making!" The Siber-loyal commander said in a triumphant voice, not knowing what kind of hell he had just unleashed on himself and his man...
"You........... bastard.............. how.................... dare you........" Future Xenest drawled in a dangerously low voice, his anger rising.
Future Brachi gasped out, seeing the scars on her husband's body glow a fiery golden yellow, before moving to grab Atama before taking him to a distance away from Future Xenest as she knew what was going to happen.
"What?" The commander asked, seeing Future Xenest turning to him, his eyes having colored a fiery yellow as well.
"HOW DARE YOOOOOOOOOOOUUUUUUUUUUU!!!!!" Future Xenest howled, a massive battle aura exploding outward from him and shooting into the sky of the ice world, causing most of the nearby ice and snow to melt instantly due to the intense heat the aura and Future Xenest himself gave off, causing everyone else to avert their eyes from the white flash covering him, before another explosion threw them off their feet.
"What was that?!" A female soldier asked.
The battle aura diminished as soon as it came in size, but remained active... but that wasn't the most horrific change... Future Xenest's entire skin, from the tip of his hair down to the nails of his toes had a dark golden glow, making it impossible to identify he was still clothed or butt-naked now. His teeth had elongated into sharp fangs like with a normal predator, his eyes were a burning hot fiery yellow, indicating the rage boiling within him and he had adopted a more feral stance, making it more clear he had completely snapped. But that wasn't the shocking change... the greatest change was that, sprouting from his shoulders and upper back, were FOUR ENORMOUS arms that each had a fiery glow to them... as if they were made out of pure energy! It was as if Future Xenest had harnessed his energy in a way Medusa Gorgon and her band could utilize her black blood to make their weapons from it and simply had grown enormous arms right there... and he was RAGING MAD! Future Brachi gasped in horror; even though she still outclassed her husband in strength, Future Xenest made up for it with being able to harness his sheer anger and wrath as weapons and tools, allowing him to bring down beings stronger than he was... and the appearance of his Berserker form overall intimidated her greatly, simply because those enormous arms were likely capable of even tearing someone like her apart or just crushing her within them.
