Dark Sword is the final fighter to unlock in Raiden Fighters 2: Operation Hell Dive, as a secret character that is very similar to Judge Spear. This ship is a black version of the Judge Spear. Notice the connection between the "Viper" class of space fighters including Judge Spear and Blue Javelin. They all have names of medieval melee weapons.
Powers and Abilities
Dark Sword's Vulcan Cannon remains the same as Judge Spear's, and its missile weapon is very cool. It is similar to the Blue Javelin's Burst Missile weapon, but much better. If fully powered up, Dark Sword can fire up to 25 missiles at once, covering almost the entire screen and giving itself a very good defense rating. The missile weapon is later on in Raiden Fighters Jet inherited by the Ixion, but powered-up even more.
