Ultima Cannon

Ultima Cannon is Terra's ultimate Shotlock in Kingdom Hearts Birth by Sleep. As they are extensions of Terra, Terra-Xehanort and the Lingering Sentiment can use this attack as well. The Shotlock transforms Terra's Keyblade into a large cannon, which launches two large balls of energy at the opponent. It is obtained by completing the Keepers of the Arena mission in the Mirage Arena.

A variation of this ability is used by both the Lingering Sentiment in Kingdom Hearts II Final Mix and Xehanort in Kingdom Hearts Birth by Sleep.
