Princess Cannon

The Princess Cannon is a special weapon in Splatoon 2. It is not part of any main weapon's set, and is instead only available in the final Shifty Station layout, MC.Princess Diaries, where it appears in the middle of the stage when there is one minute left until the battle ends. It is similar in appearance and function to the from Splatoon, although the beam is much larger and it takes a little longer to charge up.
