Automaton

Bio
They are rumored to be machines used in the prehistoric times to prevent robbers from infiltrating the ruins. With all this time past, even though the ruins they guarded and their master were gone, Automatons would still search for and obey their master's orders.

Automatons' sturdy metallic bodies can withstand attacks from all directions. They also have an automatic destruction mode, such that when they receive their master's orders, they will enforce them until the targets have been destroyed.
