Chaos Spear (カオススピア, Kaosu Supia?) is a recurring Chaos Power in the Sonic the Hedgehog universe. It is one of Shadow the Hedgehog's signature techniques. When performing this technique, the user fires a bolt made of chaos energy.
Chaos Spear is a technique where the user channels raw chaos energy as a form of electricity into a spear-shaped energy construct and then fires it as an energy bolt. Its power-level can be adjusted by the user, making it weak enough to just stun a target or powerful enough to inflict injuries. Users like Sir Lancelot can also channel the Chaos Spear's energy through swords when firing them. Once manifested, the Chaos Spears are substantial enough to be physically grabbed and get embedded in surfaces.
The means of firing the Chaos Spear are numerous. The most recognized way is just by swinging the user's hands forward to fire them as arrows. Other methods include hurtling a cascade of spears in an energy burst, manifesting the spears in midair and shooting them at the target, firing them from the palm of the hand, or just grabbing and then throwing them manually like actual spears. Additionally, entering a Super State amplifies the Chaos Spear's power significantly, to the point where a single one can blow up an entire building.
