The Thousand Knives is one of the final bosses in Dariusburst. Resembling a massive mechanical lionfish, it mainly attacks with dozens of blade-like drones that can fire lasers of varying sizes.

A Belsar Flagship in the shape of Lionfish. The Warship itself carries various units that can detach from the hull and interact by themselves, giving the warship an almost 360 degree firing range. The units themselves are fragile, but powerful. The units can also give laser formations that can trick and trap opposing fighters. The burst gun is attached to it's most powerful units.
Thousand Knives's purple color and use of narrow funnels/bits may be a homage to the RX-93-n-2 Hi-v Gundam. Moreover, the "bits" themselves somewhat resembles the said mobile suit's fin funnels.
