Chaos Emerald Saga
Missile Wrist was the first robot deployed by Eggman against Station Square, announcing his presence to the world. After forging a path of destruction through the city, it carried itself to the top of a building, only to be attacked, by Tails and Christopher Thorndyke in the Tornado 2, an attack later joined by Amy Rose and Knuckles. It wasn't until the arrival of Sonic that the tables turned. Using the robot's own abilities against it, Sonic was able to destroy the robot.
Missile Wrist's legacy didn't end there, however; its remains were transported over to Area 99 for study by the government. Eggman following uses of his Selection Machine would imply that the doctor had rebuilt Missile Wrist.
While displaying little personality, Missile Wrist was capable of basic speech.
Powers and abilities
Missile Wrist's name is partially a misnomer. Its primary method of attack is two cord based missile heads that do not act as true projectile explosive weaponry, but rather as recoil-based projectiles. These are shown to have an extraordinary range, likely ranging for hundreds of meters. Also they appear to be fired like true rockets or missiles. In addition, Missile Wrist possesses a missile rack on its upper chest, five tubes being present.
Missile Wrist has shown itself to be invulnerable to basic projectile weaponry, ranging from high powered rifles to the Tornado's firepower.
E-23 Missile Wrist is one of the very few Sonic X Robots to receive his own action figure. However, his package only identifies him as "Robot" and he is not correctly proportioned to the other figures: Sonic and the others are all taller than him.
