Lassoo (in the original Lassoo) is a pistol that ate the dog-fruit, model: dachshund.
It belongs to Mister 4, making him a member of the Baroque Company.
Thanks to the advanced technology on the Grand Line, it was possible to combine a gun with a devil fruit. This technology was developed by Dr Vegapunk.
Since Lassoo always seems to have a cold and therefore always sneezes, he is very important to the strategy of Mr. 4 and Miss Merry Christmas. Because when he sneezes, he hurls exploding baseball balls at his opponent, which can be hit by Mr. 4, thus defeating their enemies.
- Lassoo’s favorite food is dog food.
