Eye Lasers (光線眼 Kōsengan) is a technique used by many fighters.
The user shoots laser-like beams from both eyes. The potency of the Eye Laser technique varies, but most of them are very fast and able to nullify weak attacks and small projectiles, as well as cripple opponents and damage other objects. The Eye Lasers can vary in color from red to a bright blue-tinged white.
This attack is first shown in the series when used by King Piccolo aboard Pilaf's Airship to destroy the Electric Rice Cooker used by Master Mutaito to trap him for centuries. Later on, aboard the airship while on his way to King Furry's castle, King Piccolo uses it to zap a hole in East City on Pilaf's model of the Earth, and later to kill one of the gate guards of the King's castle when he and his son Piano invade the base. He also uses it to zap Goku in the right kneecap during their second fight, when Goku's speed began to give him too much difficulty.
In the 23rd World Martial Arts Tournament, Tien Shinhan uses a variation of this attack after performing the Multi-Form technique, firing a single beam from his third eye to stun an airborne Goku. This technique is named Mystery Ray in Dragon Ball Z: Ultimate Battle 22.
In the same tournament, Piccolo Jr. uses it to nullify Krillin's twin homing beams and again in an attempt to break a grapple with Goku. Piccolo later uses it near the beginning of Gohan's combat training to silence Gohan's complaints about harsh conditions, and again as a surprise attack to halt Gohan's offensive. Much later in the series, Piccolo uses the attack while grappling with Frieza.
In the anime only, Yetti uses it against Nappa and Vegeta on Arlia. Also only in the anime, Nappa performs the Eye Laser technique when attacking the Earth's Military forces while he and Vegeta are waiting for Goku to arrive.
Frieza is shown using the attack in Namek Saga as well as Frieza Saga; his Eye Lasers are much more powerful, allowing him to blast huge holes in walls and attack weaker opponents. It is shown in a flashback that all the leading Saiyan members of King Vegeta's force attacking Frieza's base are repelled by just one Eye Laser attack of the untransformed Frieza. Frieza also uses the attack during his battle with Goku, with it appearing similar to the Darkness Eye Beam this time.
In the anime only, Guldo uses eye lasers while attacking Chiaotzu on King Kai's Planet. Kami also uses this technique during the Garlic Jr. Saga in an attempt to slow down Garlic Jr.'s attempt to take over The Lookout.
Lord Slug uses a variation of the Eye Lasers, the Darkness Eye Beam, in both his base and Great Namekian forms against Goku in the movie Dragon Ball Z: Lord Slug. Cooler also uses this variation in Dragon Ball Z: Cooler's Revenge, in an attempt to kill Gohan but Goku gets in the way of the blast however. Meta-Cooler also uses a variation of the attack, the Lock-On Buster, against Goku and Vegeta in Dragon Ball Z: The Return of Cooler but they escape via Goku's Instant Transmission; Meta Cooler's version of differs in function and overall power: his is nearly invisible sparks of light that explode after a certain distance.
Later in the series, Android 20 uses an even more powerful version of this technique, the Bionic Punisher, to destroy a large section of South City. When Android 19 fights Goku, just before Android 19 is about to finish Goku, Android 20 uses this technique to attack Piccolo when the latter attempts to help Goku. Android 19 uses this during his battle against Super Saiyan Goku. Cell uses Eye Laser against the Earth's Military while he is fighting with Piccolo in Gingertown. Later, Android 16 uses it against Imperfect Cell in order to free himself from a stranglehold. Android 16's version was named Eye Beam in Dragon Ball Xenoverse 2.
