In the distant future, humanity has ventured beyond Earth to colonize both the inner and outer planets of the Solar System. To safeguard these colonies and uphold law and order throughout the system, the Earth Federation Government (EFG) was established. However, many settlers soon began to resent the EFG and its sphere of influence, straining relations between the central government and the colonies. While a fragile peace was being negotiated between Earth and the colonies, a non-human race known as the Deathcula invaded the System. Without provocation, they attacked the colonies, killing many colonists. The EFG quickly realized that the Deathcula possessed technological superiority, leaving their forces hopelessly outmatched. To secure a chance at survival, Dr. Charles Louvre developed a transformable starship called the Bismarck. Recognizing that an advanced team of specialists was needed to operate the Bismarck, four individuals came together and were tasked with protecting the outer colonies from further Deathcula attacks.
