Like their predecessors Mechanical Monsters ("kikaiju"), Battle Beasts are armed with a variety of weapons such as ray beams, missiles, bombs, swords, spears, axes, nets, acids and drills. However, they are made of mechanical parts combined with organic parts, and were controlled by human brains. For example, a Mikene's Warrior is permanently placed and interfaced with the Battle Beast body that he can move like his own. In a way, the Battle Beasts are like giant cyborgs. As a result of this, most of them have a distinctive human head or face placed on the mechanical body, usually somewhere on the torso or on the head itself.
