Mecha One, to battle the growing nuisance of the humans has developed a new drone that can slice through even the toughest armour. Meanwhile being protected by tough durasteel plated armour and an energy shield protecting the actual drone piloting the larger mecha-drone.
About this creation
The saw drone, utilising its armoured saws as partial shields. It is about the average size of a drone, maybe only slightly larger but uses new technology.
The SAW drone has been dubbed so because every weapon is connected to saws which slice up their enemy. But if that was not enough their main melee weapon has a double laser sword for when the saws slice deep enough the laser begins to fry the insides of the enemy AEGAKS.
The gun is powered by dual power rods, shielded of course, which are the secret to its immense charge.
Finally, its final weapon are two further saw 'limbs' which can retract in resting position (shown) or go out and help to destroy enemy AEGAKS quicker.
Due to having so many saws they need to carry replacements so that if in battle due to wear and tear the blades need to be replaced. Due to the large amount of work the blades are put through they need regular maintenance.
They have thoroughly armoured feet and even have a claw on each foot so that they can dig into a mountainous terrain and to reinforce themselves better when digging into an enemy.
