Thousand Knives is one of the final bosses from Darius Burst, reappearing again in Darius Burst: Another Chronicle. It is one of Belser's flagships leading their last attack on Darius, being shaped after a lionfish.
Thousand Knives is a battleship which specializes in all-range attacks, being able to detach several fin-like units from the main body, which all act as drones. Not only can the drones shoot in all directions, they can also protect the main unit from incoming enemy fire and even circle around the player. Each of the drones can fire the Burst Gun separately, being able to concentrate their fire to form a more powerful beam.
