The Chaos Spear has been used repeatedly in Sonic X to a great effect, often allowing Shadow the Hedgehog to brush aside powerful, and occasionally physically stronger, opponents with ease. Using it, he fought off numerous ships, punched holes in the Blue Typhoon and been able to tear the leg off of the X-Tornado, all with minimal effort. In another episode of the series, Super Sonic uses what appeared to be yellow energy bolts, an ability which could possibly be a derivative of Chaos Spear, to strike down a group of Metarex soldiers before engaging in combat with Super Shadow; though it's not confirmed if this truly was Chaos Spear or not, as Sonic never said a word while doing this attack; however, later in the series, Shadow doesn't say a word when performing the move.
