Gun Beetle

The Gun Beetle (ガンビートル) is a robot deployed by the military organization Guardian Units of Nations and is a part of the Beetle series. It appears as an enemy in Sonic Adventure 2, Sonic Adventure 2: Battle, Shadow the Hedgehog and Sonic Generations.

Appearance
In all of its appearances, the Gun Beetle greatly resembles the Mono Beetle presented in the respective games, but more advanced as it has a gun attached to its underside.

Attack Patterns
The Gun Beetle attacks opponents by shooting bullets at them with its gun. It does not move around much, but instead remains hovering in one place while aiming and shooting at enemies from afar.

Sonic Adventure 2 and Sonic Adventure 2: Battle
The Gun Beetle first appeared in Sonic Adventure 2 and its remake Sonic Adventure 2: Battle. When attacking the player, it shoots one projectile at a time. It awards a hundred points when destroyed. They appear in the following stages:

Shadow the Hedgehog
In Shadow the Hedgehog, the Gun Beetle carries a variety of guns that it can use during battle and which can be picked up by Shadow the Hedgehog when it is destroyed. These weapons include:
 * Sub-Machine Gun (Heckler & Koch MP5)
 * Semi Automatic Assault Rifle (SIG SG551)
 * 4-Shot RPG (M202 FLASH)

Sonic Generations
In Sonic Generations, the Gun Beetle appears in City Escape and fires single projectiles again.

Sonic X
The Gun Beetle made an appearance in the anime Sonic X. Following Perfect Chaos' attack on Station Square, the Gun Beetles were built by G.U.N. to combat the growing threat of Doctor Eggman, after having been given clearance to being constructed from the President. In this series, they can shoot continuous laser blasts that can cause large explosions.

When Sonic the Hedgehog had been framed by Shadow the Hedgehog for the theft of a Chaos Emerald, a swarm of Gun Beetles were sent to locate and stop Sonic. Once they found him, however, the robots proved no match for the blue hedgehog.

Trivia

 * In Shadow the Hedgehog, in a number of stages (such as Circus Park), its full name is a "G.U.N. beetle drone sentry".
