"Now you perish!"
Meta-Cooler in Dragon Ball Z: Dokkan Battle

Lock-On Buster (ロックオンバスター Rokku On Basutā) is a cybernetic-enhanced version of the Darkness Eye Beam used by the Meta-Coolers.


First, the Meta-Cooler uses his 3D Scan Mode to locate his target and lock-onto them, then creates a small amount of sparkling energy in front of his face. Then, he shouts "I got you!" and fires a fast-moving beam that leaves behind a sparkling trail and creates a huge blinding explosion upon impact.

After avoiding Vegeta's Big Bang Attack using Instant Transmission, Meta-Cooler appears and knees Vegeta in the stomach, surprising and temporarily knocking out the Saiyan prince. Using his cybernetic modifications to locate Goku, Meta-Cooler punches Vegeta towards Goku and fires the Lock-On Buster at Goku and Vegeta, leaving them moderately injured.

Lock-On Buster was named in the Budokai Tenkaichi series where it appears as one of Meta-Cooler's Blast 2.

In Raging Blast 2, the Lock-On Buster is a Rush Attack.

Though Meta-Cooler is not playable in the game, his Lock-On Buster technique is one of the Ultimate Tenkaichi Hero's learnable Super Attacks in Dragon Ball Z: Ultimate Tenkaichi. Despite the hero's apparent lack of any cybernetics, the Hero will view their opponent in 3D Scan Mode briefly, making the attack seem somewhat implausible unless the Hero has a scouter equipped.

In Dragon Ball Z: Dokkan Battle, Lock-On Buster appears as one of the Super Attacks of Meta-Cooler. Despite the nature of the attack locking onto the enemy, certain characters such as Hirudegarn and Janemba can still dodge it.

In Dragon Ball Legends, Lock-On Buster appears as the Special Move Arts for Metal Cooler (DBL12-02S).

Lock-On Buster appears in Dragon Ball Heroes, where it was added in Universe Mission 9 as Rampaging Meta-Cooler's Super Attack.
