Thunder Arrow (Archie)

The Thunder Arrow is an ability utilized by Knuckles, when he became the new Enerjak.

Overview
The Thunder Arrow is an ability akin to the Chaos Spear, powerful enough that, at the hands of Knuckles/Enerjak, was able to defeat Shadow. However, when he tried to use it against Super Sonic, it had no effect due to the fact that he was invincible.

Following his return to normal, Knuckles was shown to be capable of utilizing the move, as he did in battle against Dr. FinitevusEdmund, a possible future descendant of Knuckles, used it against Prelate-V.

It acts as a sort of Chaos-powered lighting bolt that electrocutes its victims. As such, it's effect, appearance, and even coloration are notably diffrent from it's main counterpart.
