Hajime's Pile Bunker

“Nice job, Yue!” Hajime stood on top of Miledi’s chest and pulled his trumpcard out of his Treasure Trove. The object he pulled out was a two and a half meter long cannon. The outside was covered in all manner of odd knobs and switches, while the inside was loaded with a twenty centimeter wide jet black spike. There were four sturdy stands attached to the lower part of the cannon, while the middle part connected to his prosthetic arm, allowing him to operate it. Hajime used the arms to hold it in place over Miledi, who couldn’t move, and fired two anchors for good measure. All told, there were six stands firmly holding the cannon in place. Then, Hajime started pouring mana into it. Red sparks started flying off the cannon, and the jet black spike inside it started to rotate.

Whiiiiiiiir! The spinning spike let out a high pitched whirring noise. Hajime’s smile was so ghastly that had Miledi not been a golem, she surely would have stiffened in fear.

This was one of the auxiliary weapons for his left arm, a pile bunker. With his compression synthesis, he had managed to fit a four-ton mass into a spike twenty centimeters wide and one meter long.

The entire thing was coated in a thick layer of Azantium, making it the densest, hardest object on the planet. He ignited the massive amount of compressed blastrock inside the pile bunker and accelerated it with Lightning Field for good measure.

“Eat this.” He drove the spike straight through Miledi’s heart, as if he were staking a vampire. With a resounding crash, his pile bunker pierced through Miledi’s Azantium armor. Cracks spread around the point of impact, the damage spreading throughout the plating. The platform Miledi was stuck to had nearly shattered, the force of the impact pushed it down a good distance, and the friction of the spinning pile bunker created enough heat to make plumes of smoke rise from her chest.
