The Centurion Bug is a Biological Weapon developed by Chemical Dyne. She is more powerful and dangerous than her children but that doesn't say much. It appears to be a six-legged giant ant and is roughly five times the size of the Warrior Bugs. Her only weapon is a burst shot like twin energy cannon fired from her back. Due to being biological the enemy cannot lock on to this unit unless it is equipped with a bio sensor. She also cannot be seen on the radar. Unlike her children however she is much less mobile, basically stationary and her massive size makes her an easy target.
