Royal Drum Crown 7-Shot Bliking Cannon

The Royal Drum 7-Shot Bliking Cannon (ロイヤルドラムクラウン７連散弾ブリキング大砲) is Wapol's ultimate weapon. It is capable to shoot 7 powerful shots.

History
Wapol was going to use it to defeat Monkey D. Luffy but he could not get the thing working due to the over-freeze condition and the cannon holes became a nesting for the Snow Birds.

In the ninth movie, Wapol ate the cannon, along with his older brother, Musshuru, and merged with them, with the intention to use the cannon to fire his brother's poisonous spores in the form of its ultimate attack, the Fatal Bomb, to wipe out the entire population of Drum Island. The bomb was fired, but was sliced open by Roronoa Zoro and the spores burned by Franky before it could affect anyone.
