Dark Link

Dark Link (ダークオブリンク) is a technique that appears in Kingdom Hearts Birth by Sleep. It allows the user to shoot a giant beam of radiation. It is the opposite of Vanitas's Dark Cannon attack.

Mechanics
Dark Link is a class A Shotlock that has a max lock of 20 and deals dark damage. If Vanitas uses Dark Cannon or Dark Spiral at the same time as this Shotlock is used, a clash will initiate between Vanitas and the user, which can be won by rapidly tapping ( in Japan).

Kingdom Hearts Birth by Sleep

 * Vanitas's D-Link has Dark Link as its Shotlock.
