Biomechanoids are enemies that appear in Asteroids.
They resemble human that some of it's parts has been replaced with robotic ones. They don't have lower part of their bodies - instead they have circular sawblades and above them there are two containers with purple liquid. Their left arm has been replaced with flamethrower and they have masks that covers their heads. They also have something that resemble metalic beak where their mouths should be. They have multiple melee attacks such as: sawing the player with sawblades under their torsos, piercing the player with their metalic beaks or roasting the player with their flamethrowers.
- They are the only monsters that have purple blood, instead of red or green.
