The Chaos Spear is a Chaos Power that appears in the Sonic the Hedgehog comic series and its spin-offs published by the Archie Comics. It is one of Shadow the Hedgehog's signature techniques. When performing this technique, Shadow channels a bolt made of Chaos energy.
Chaos Spear is a technique where Shadow charges raw Chaos energy as a form of electricity into a yellow-green (or red) energy construct shaped like a spear, complete with an arrowhead, and then throws it as an energy bolt. Its power-level can be adjusted by Shadow, making it weak enough to just stun a target or powerful enough to destroy a robot. Once manifested, the Chaos Spears are substantial enough to be physically grabbed.
Firing the Chaos Spears is done in two primary ways. The first method includes Shadow just thrusting his hands forward to fire them as arrows. The second and more common method includes Shadow grabbing and then throwing them manually like actual spears.
