The GunBlade

As it’s name states, it can either be a gun or blade when it transforms. Caiden developed a weapon he needed to be useful in a number of different situations given the unpredictability of combat. The gunblade would fulfill the criteria. As a Gun, the nano arm has a few modes between regular ammo based semi-automatic pistol with a capacity of 25 hollow tip bullets per magazine clip, A stun mode than can hold 15 High voltage non-lethal bullets, and Buster mode, The most powerful of the three that gathers energy to a single point in front of the barrel to let off a massive concussive force of energy. The buster mode shot is capable of taking out a military grade hover tank ( which are notoriously difficult to take down even with adequate firepower)

As a blade, it is powerful enough to slice through nearly anything given the energy layer laced on the tip and the front end of the blade.
