a badass looking multi weapon/tool that could turn into a claw, chaingun, shotgun, laser, missle launcher, railgun, impact hammer, searchlight, shield, flamethrower, wielding torch, freeze ray, medical surgeon multitool, xray machine, toothbrush, hypodermic needle, teloscope, gps, sonar scanner, sword, battle axe, flail, chainsaw, pencil, pen, branding iron, personal computer, ipod, watch, drill, vacum, hybrid propeller/rocket device that could be used to fly around, grappling hook, toaster, invisibility cloak generator and EVERY eating/cooking utensil known to man, including the spork, knork, spife and splayd.
this probably wouldnt fit into a mechanical hand so how about a super strong mech arm?
it would look something like the arm in the bionic commando remake
only without being made from my dead wife 0.o
work your magic Dr. insano!
