Darius Wiki

Unknown ship in Darius II's ending, supposed to be Belsar.

Belsar (ベルサー) is the main antagonistic force throughout the Darius Series (the only exception being G-Darius). They were originally referred to as Belser in older instruction manuals and intros, but as of Dariusburst Chronicle Saviours their name is officially translated as Belsar.

Very little is known about the Belsar, such as their origins or nature, though it is speculated they are very similar to humans due to their high intelligence and the way they always target human civilizations. Their purpose is to take over all of outer space, with their large fleets invading not only the Darius system but also other systems as well.

Belsar's invasion fleet is divided into small groups, and each fleet constitutes a unique social system or society. Basically, there is no interference or coordination in the operations between the groups, but even if one group fails and ends destroyed, consultations between the groups take place afterwards, with another group taking over the invasion of the system and resuming the attack, which has been the biggest reason for the war between Darius and Belsar to date.

Belsar greedily diverts technology from the destroyed civilizations, but the technology system of each group is different, and this has led to a reversal phenomenon in which later ships are weaker than earlier ships. On the other hand, Belsar themselves did not develop any new technologies, with much of the technology obtained being lost over time, though some groups use POWs to manage and research technology. The Burst Engine employed by their battleships was originally developed by a Belsar captive.


After the war between the people of Amnelia and the Thiima (G-Darius), the Belsar salvaged the wreckage of one of the Thiima battleships, G.T., using it's technology as the basis to create their own line of battleships. During this time the people of Amnelia migrated to Planet Darius, leaving their destroyed planet behind. Belsar would settle themselves on Amnelia afterwards, making it into their home planet and the main base for all of their operations.

Belsar launches their first attack against the people of Darius in Darius Year 201 (Darius). Darius's people were ill-prepared against the attack and the survivors were driven into the planet's interior. In order to save their people, the ace pilots Proco and Tiat, piloting spacecrafts know as Silver Hawk, are sent on a mission to defeat the Belsar's flagships and escort the people of Darius to safety. The two managed to escape from the planet with the remaining survivors, but Darius was inevitably taken over, becoming a death star. Proco and Tiat then led Darius inhabitants to the planets Olga, Vadis and the Solar System, where they established themselves and started to recover.

On Darius Year 1642 (Darius Gaiden), the people from Vadis started to migrate back to Darius. However, they are suddenly attacked by the Belsar, which almost annihilates an entire line of Silver Hawks. Two Silver Hawk pilots, Case Ardin and Anna Steiner, lead a counteroffensive against the Belsar's forces and succesfully repel them, managing to liberate Planet Darius from their influence.

Later on, during Darius Year 1813 (Darius II), the space HQ on Olga picked up a SOS signal coming from Earth. The descendants of those who migrated to the Solar System were being attacked by Belsar, so Olga sent two Silver Hawks piloted by Proco Jr. and Tiat Young, descendants of Proco and Tiat, to help them. Belsar is once again defeated, and the Solar System saved.

On Darius Year 1904 (Darius Burst), Darius is finally restored by the people from Vadis, but their happiness is short-lived, as Belsar once again launches an attack against them, using a virus which renders all of their communications innoperative, thus leaving most of their forces isolated around the space. The pilot Riga Pratica and the android “TI2” are sent in the Silver Hawks to stop Belsar's attack on Darius once and for all. With the success of their operation and all communications restored, Darius prepares a major counteroffensive force to finish the Belsar forces once and for all.

The final battle with the Belsar begins on Darius Year 1910 (Dariusburst Another Chronicle/Chronicle Saviours). The Planet Saviours, an entire squad of Silver Hawks led by Riga, fights the Belsar forces in a bid to free various planets of their influence. The Belsar were prepared for the attack, however, launching their vast fleet against the Darius forces. The war would go on for 16 years, with both sides over-exhausting their resources, but the tide of the battle would turn when Azure Nightmare, a mysterious Thiima existing within the hyperspace, intervenes in the conflict. Azure Nightmare attacks the Belsar and guides the Planet Saviors when Gigantic Bite, the ship commanding the Belsar forces, attempts to hack the communications network. With Gigantic Bite's destruction, the Belsar ends severely crippled and ceases the attack, with their remaining forces ending scattered throughout the known universe.

Belsar Battleships[]

Despite being referred to as battleships, these bosses are actually autonomous AI-controlled giant robots, heavily implied to be fully sentient. When engaging an enemy in combat, they are capable of forming a special space similar to a sea of ​​clouds called BBF (Big Battle Field), in which the attack power of the Belsar ship increases.

The marine life motifs they use for their battleships was obtained from the Thiima battleship G.T. destroyed during the Amnelian era, with no connection between Belsar's ecosystem and the design motif of their battleships. All of Belsar's battleships were given codenames by the Darius inhabitants based on their characteristics. Their true names in the Belsar Army are unknown.

  • It is not explicitly stated what exactly is the Belsar, if they are human or alien. They were originally set up as a ghost-like entity reflecting the human's fighting desire.
  • In Syvalion, the Belsar are shown to be humanoid creatures who originated from the Varia, and much like them were amorphous mutants who assumed a human shape.
