In the distant future, humanity has explored beyond Earth and established settlements on both its inner and outer planets within our Solar System. To safeguard these colonies and maintain order in the solar system, the Earth Federation Government (EFG) was formed. However, as time went by, many settlers began to resent the EFG's authority and influence over their lives. This tension between the central government and the colonies eventually led to a strained peace agreement. While this uneasy truce was being established, an unexpected threat emerged: a race of non-human creatures known as Deathcula invaded our solar system without warning. They launched devastating attacks on the colonies, resulting in significant casualties among the colonists. The EFG quickly realized that they were outmatched technologically and that their forces were no match for the Deathcula's superior weaponry. In a desperate bid to ensure survival, Dr. Charles Louvre developed a transformable starship called the Bismarck. Recognizing the need for an elite team of specialists to operate this advanced vessel, four individuals were assembled and tasked with safeguarding the outer colonies from further Deathcula attacks.
