Enerbeam

Enerbeam is an object utilized by Sonic the Hedgehog, Miles "Tails" Prower, Amy Rose, and Knuckles the Echidna in the video game Sonic Boom.

Description
Enerbeam is a versatile whip which can be used for many functions, both navigation- and combat-based. It can activate gimmicks in order to travel through a stage or pull protective shields away from enemies in order to expose them for attacks.

Appearance
Enerbeam is, as the name implies, an energy beam. It takes the form of several lightning bolts intertwined to form a whip. It can extend when necessary, behaving much like a bungee cord. Its color is that of the user (e.g. Sonic's Enerbeam is blue).
