Blue Falcon is one of the bosses in Shadow the Hedgehog. It is a large hovering machine that is in the same model series as Heavy Dog. It is used by a G.U.N. soldier in an attempt to stop Shadow and Black Doom's Eye from reaching the Eclipse Cannon aboard the Space Colony ARK. It wields an area-of-effect particle beam cannon and several rocket launchers on its side which can be broken off and used against it. It also appears as a card in Sonic Rivals 2.
- It is possible that its name is a reference to Nintendo's F-Zero series, where the main character, Captain Falcon, races in a machine known as the Blue Falcon. The same thing can be said for Black Bull, which is also the name of the machine the main antagonist of the F-Zero series races. As SEGA helped develop F-Zero GX, this is not entirely unlikely.
- The music that plays during this boss fight is a remix of GUN Mobile, which plays in Sonic Adventure 2 during the boss fight with F-61 Bigfoot, B-3x Hot Shot and R-1/A Flying Dog.
