The Chaos Spear is a move that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is one of Shadow the Hedgehog's signature techniques. When performing this technique, Shadow channels a bolt made of energy.
Chaos Spear is a technique where Shadow charges raw energy as a form of electricity into a yellow-green energy construct shaped like a spear, complete with an arrowhead. Once manifested, the Chaos Spears are substantial enough to be physically grabbed by Shadow and be wielded like actual spears.
