Now i know how just about everyone likes godzilla and believes he can cut down anyone who gets in his way but you don't know border defender

Border defender is a automated defense robot with a human intelligent like AI system which lets him think and react like a human, his weapons system are;

ion cannon: giant fission powered weapons with a crystal that when jolted with electricity it converts that energy into a lethal particle beam where the crystal acts as a lens for a focused shot, the beam is so powerful it can tear through matter atom by atom, dispersing and ripping the targeted area to pieces.

magma cannon: a weapon that uses a solid material like metal where it uses friction to melt the material into its molten state before firing it into a jet of hot molten blub, the molten material would then solidify later on.

Border defender also has a shield generator based off a reverse engineered alien tech which rapidly re-generates if not too much fire power is focused on the unit.
Border defender is also cunning and won't stop til the enemy he is sent to destroy is eradicated
