This baby has taken some serious patience to complete all
the details and also design it as I draw, which is no easy task.
About the robot,
This robot uses electricity which it produces with the use of Electro Amplifiers and special Tesla coils,
These amplifiers are normally hidden on it's body under plates, as you can see on it's right shoulder a Tesla coil has telescopically popped out, and the amplifiers have lifted upwards.
It can also use a wide range of lightning based weapons, like a lightning cannon and other such guns, these are carried as normal weapons rather than being attached to the robot as having large attached weapons is too cumbersome and unreliable in battle situations.
When the robot is in dire situations and has stored enough energy, it can then produce a powerful wide radius lightning blast from it's body with the use of a multitude of amplifiers and coils on it's entire body, all activated at once, this causes massive damage to the surrounding area, but this attack causes allot of heat to the robot's exterior, and requires a prolonged cool down period before it can use any lightning based attacks again.
