|Appears In||Darius Force|
Bio Hazard is the first boss from Darius Force. It is shaped after a daphnia/water flea.
Bio Hazard will initally attack with a three-bullet spread from his arm. After the arm is destroyed he will spread bullets in a counterclockwise pattern and release bubbles which pursue the player but can be destroyed. After the large bubble protecting his body is destroyed he will use homing missiles along with the bullet spread and a laser in the harder difficulties.
