Lassoo is Mr. 4's gun. At some point earlier in the timeline, it consumed a Devil Fruit through some unknown method which allows it to become a living dog, though before, it was nothing more than a gun. It is classified as a Type D creature, "Small Savage".
Lassoo is a sandy-brown gun, similar to a bazooka, that has handles on the sides and a contoured barrel. Lassoo is always suffering from some kind of cold that makes him have a running nose and sneeze (which makes him fire cannonballs). It is unknown if this is an actual disease or a side-effect from being an inanimate gun unnaturally absorbing a devil-fruit.
He seems to be very loyal to his master, as he did everything he said without question.
Abilities and PowersEdit
- Further information: Inu Inu no Mi, Model: Dachshund
The fruit gave the gun the ability to turn into a dachshund, becoming literally a gun-dog. In turn, Lassoo gains animal sentience and becomes a mobile mortar, increasing efficiency in combat. The fruit is known as the Mutt-Mutt Fruit in the 4Kids English dub as he is a mixed-breed dog, also called a mutt. During battle, Lassoo functions as an automatic baseball pitching machine of sorts for his master to hit the baseball ammunition with towards their targets.
On Mr. 4's call, Lassoo would cough up a seemingly infinite amount of exploding baseballs that (to Usopp's surprise) are not balls that explode on impact, but when a timer runs out. According to Chopper, Lassoo's baseballs are as heavy as cannonballs, thus ruining Chopper's plan to throw the ball back towards the agents before the baseball explodes. On the contrary, Mr. 4 can use his immense strength to strike these cannonballs with his 4-ton baseball bat, sending them flying at an incredible speed and accuracy at the opponents.
Lassoo was ultimately defeated when Usopp tricked Mr. 4 into slugging Miss Merry Christmas with his 4-ton bat. While Mr. 4 was shocked at what had just happened, Usopp took advantage of this time to fire a hammer at Mr. 4's gut using Chopper's horns as a slingshot. Mr. 4 then flew into Lassoo and hit a stone structure thus knocking them both out. Lasso coughed up one last exploding baseball that completely incapacitated the Mr. 4 team. Lassoo was then arrested by the Marines along with the rest of Baroque Works when Crocodile was defeated.
Miss Goldenweek's "Operation: Meet Baroque Works"Edit
After all the members of Baroque Works have been exposed, Miss Goldenweek, Miss Valentine, and Mr. 5 fly to the Marine base and try to break out all of the captured members of Baroque Works. They succeed in rescuing Mr. 4, Miss Doublefinger, Miss Merry Christmas, and Lassoo (Crocodile and Mr. 1 decide to stay behind). Lassoo then helps out around the new Spiders Cafe as the new mascot.
- When Miss Goldenweek used her Rainbow Color Trap on Lassoo, it is revealed that his dream is to become a tank. Later, when the released members of Baroque Works opened a new Spiders Cafe, Lassoo is shown in his new tank form instead of his old gun form.
- When Lassoo "transforms" into his tank form, his name is romanized on his tank. On the right side of the tank is "RA". On the left side of his tank appear the letters "SS", followed by what appears to be either a U or O. As the rest cannot be seen, it is impossible to determine the remainder of the romanization.
