Spark Beetle

Spark Beetle is a robot part of the military organization G.U.N's Beetle series. It appears as an enemy in Sonic Adventure 2, Sonic Adventure 2: Battle and Shadow the Hedgehog.

It is basically a Mono Beetle equipped with a electrical shield. It electrifies itself with this shield to protect it from attacks temporarily until the shield switches off.

In Shadow the Hedgehog, a Spark Beetle's shield can protect it from gunfire as well as regular attacks. Also in this game, the shields are electrical rings instead of the spherical shaped shields seen in Sonic Adventure 2.
