Blue Eagle

Blue Eagle, also known as Vulkan Fighter, is a mass-produced combat plane deployed by the military organization Guardian Units of Nations. It appeared in Sonic Adventure 2, Sonic Adventure 2: Battle and the Nintendo 3DS version of Sonic Generations.

Description
The Blue Eagle is a combat plane created by the G.U.N to hunt enemies and destroy them. It is equipped with missiles that it drops at the player and Machine Gun to shoot them with.

Overview
In gameplay, the Blue Eagle can be destroyed easily with the Homing Attack, Light Speed Attack or Lock-On Missiles when they are very close to the player. They appear in Metal Harbor, Weapons Bed, Mission Street and Radical Highway.

In Radical Highway, as Shadow reaches the end of the updraft section, a Blue Eagle will come down and fire its machine gun. A similar case occurs in the hard mode of Mission Street, where the Blue Eagle will track the player throughout the stage. In the majority of the aforementioned stages, these Blue Eagles will make several quick sorties and fire roaming missiles at the player. These Blue eagles give 500 points when they are destroyed.

Trivia

 * The Blue Eagle strongly resembles the Sukhoi Su-27 Flanker, a Russian made fighter jet.
