Belsar

The Belser is the main enemy from the Darius series. They use the technology of a forgotten alien race known as Thiima, having a lot of huge battleships shaped like aquatic lifeforms under their disposal.

After most of the natural resources from Earth were depleted due to centuries of misusing, the humans started to search for inhabitable planets to live, eventually finding a similar solar system and settling on a planet they named Darius. There, the humans started a new life and quickly developed in society and technology, learning to never commit the same mistakes from their ancestors. However, some believed that this wasn't enough and that humans should atone for their sins. Soon, the Belser army disturbed Darius peace with a full scale attack, to which Darius answered by sending a line of spacecrafts know as Silver Hawk, led by the ace pilots Proco and Tiat. The two managed to thwart Belser's attack, but not without a cost, as Darius was considerably damaged. Proco and Tiat then led Darius inhabitants to the planets Olga and Vadis, where they established and started to recover, always with the fear of Belser's menace.

Many years later, the people from Vadis started to migrate back to Darius. However, they are suddenly attacked by the Belser, which almost annihilates an entire line of Silver Hawks. The ones who weren't destroyed fought back the attackers and repelled them. Later on, the space HQ on Olga picked up a SOS signal coming from Earth. The descendants of those who remained on Earth were being attacked by Belser, so Olga sent two Silver Hawks piloted by Proco Jr. and Tiat Young to help them. Belser is once again defeated.

After much time, Darius is finally restored by the people from Vadis, but their happiness is short-lived, as Belser once again appears to destroy them. The pilot Riga Pratica and the android “TI2” are sent in the Silver Hawks to stop Belser's attack on Darius once and for all.
