The Heavy Soldier Vajra is a sizable and powerful spaceborne organism with a mottled-green, deep crimson carapace that features some strange gold-color patterns. The creature has little brain matter but what little it has is not necessary for it to live and move. The body of the Heavy Soldier Vajra is covered in a tough bio-energy conversion armor similar to that found in the variable fighters.
However, the Heavy Soldier's bio-energy conversion armor is so strong, it is almost impervious to all but the heaviest of weapons. Despite its larger size and bulk, the Heavy Soldier possesses high maneuverability. The large, prominent "horn" on their back is a biological heavy quantum reaction beam gun of equivalent firepower to the guns of a space cruiser. They also generate bio-micro-missiles by growing them internally and possess folding forewings and hindwings for flying within an atmosphere. The Heavy Soldier Vajra exists by the tens of thousands in a space battle group.
