Major

A Major is a high-level enemy of any species or class. They can be distinguished by their yellow health bars and sometimes a unique name. These enemies have more health and attack power than regular enemies, and can even be equipped with absorption shields. Majors can appear anywhere from Patrol to Raids and can come in the form of any enemy.
