Dark Cannon

Dark Cannon (ダークキャノン) is Vanitas's Shotlock in Kingdom Hearts Birth by Sleep. Vanitas Remnant can also use this Shotlock, and when Ventus uses his Vanitas D-Link, his Shotlock becomes a light-version of Dark Cannon named "Dark Link". Dark Cannon generates three crystals in a trigram formation which project rays that fuse and become a giant beam of dark energy.
