The Leo Nunchaku (レオヌンチャク Reo Nunchaku) is the first weapon of Ultraman Leo.
It was created with the smoke stacks of a factory's chimney and Leo's psychokinesis. The weapon was rendered unusable after Alien Kettle destroyed the tops of the weapon with his spear.
In the final episode of Sevenger Fight, Leo arrived to assist STORAGE's Sevenger (piloted by Yoko Nakashima) in against an army of monsters from his home series. As seen from his arrival, Leo utilized the Leo Nunchaku for the first time in 47 years.
- An article of a Comic Rise Magazine for 2nd graders explained that Leo was originally planned to have a weapon like Ultraseven, whom Leo succeeds. The nunchaku was only ever used once however, and was eventually replaced with the Ultra Mantle as Leo's weapon.
