Odious Trident is one of the final bosses of Darius Gaiden, being fought in Zone Y. One of Belser's leader flagships stationed at Planet Darius, it is attacking the natives from Darius forests, apparently intending on destroying the forest. It is shaped after a sunfish.
Odious Trident has various weapons concealed on it's fins, which it can detach to serve as attacking drones. It has a huge laser cannon on it's back, which it uses regularly in an attempt to trap the player. After it is destroyed, the natives welcomed the Silver Hawk pilots, congratulating them for saving the forest.
