Kyle started his journey to Winterfell, while in One Piece world. Vegapunk has completed all his Formalities for the Space Space Fruit. It is good for Warping, and Creating Tiny Space Pockets. It is not a attack power Fruit, rather it was used as a Utility power for traveling and Storage. Here this fruit actually overlaps with many other fruit abilities but had less effectiveness in those ability.
Warping is here similar to Warp Warp fruit but it is not instantious Teleportation, rather it is to fold Space to move from one place to another. Similar to Door Door Fruit where The Door Door Fruit has a seperate Space to hide, which the Space Space fruit Lacks. It can create multiple Pocket Spaces which can be shrinked or expand depend upon user's Strength.
The User could store living or Non Living Objects inside the Pocket Space and control it, where the Strong People could easily break the Pocket Space. The User has absolute control over the Pocket Space. The Space Space Fruit's direct Nemesis is Tremor Tremor Fruit where this ability coincides with Op Op Fruit and Paw Paw Fruit. While last is he could create a Repulsion and Attraction point which coincides with Magnet Fruit and Gravity Fruit Ability. Kyle has many options for the devil fruit which is far stronger, especially the Momonusuke's Pink Dragon Fruit which makes him far stronger.
Or he could go and Kill Enel and trap the Lightning Logia to get the Devil Fruit. but the Space Space Fruit allows the people to store the Living Beings. By which he has the chance to transport people to Different Worlds to help him. Kyle then finally after getting confirmation from Vegapunk, he ate the Devil Fruit, but when he took the first bite. He felt he has eaten the Wet Sand.
He with great effort swallowed the first bite and threw away the rest. As the first bite is what that matters. Kyle did not feel any changes at the moment. Vegapunk " Try feeling the space and warp it. " Kyle tried feeling it, at the moment he could feel the Space as if it is a 3d fabric. He with his mind folded the Fabric and moved.
He instantly moved to 15 m from his initial position. More the distance to be travelled more the energy is being Consumed. He then tried attraction, he this time instead of Folding he pulled the Fabric towards himself repeatedly targetting a Pen. The Pen flew straight to him. He then did the opposite of pushing away the Fabric stretching it outside. Where Vegapunk and the others felt a mild repulsion.
Finally the moment of Truth that Kyle has been waiting. He created a small Round Pocket Space. He felt the Small Orb in his hands is entirely seperated as if they are two different Fabrics. He can expel anything and take in anything acting like Storage device. He can even control specific gas to be expelled. He tried creating another orb and he created until 20 where he felt weak.
He then stored the Orb in his Original Pocket Space. And felt that it still exists and not at all affected. Only remaining thing is to identify whether it could affect the living beings, Kyle " Doctor, is it possible to have any living organism to be tested. " Vegapunk thought for a while and then brought a Monkey that was mean for Devil Fruit Experiment.
Kyle allowed the monkey to be captured in a Space Pocket with enough Air. Where Monkey suspended and tried to struggle it's way out. Kyle could feel that the amount of Oxygen it consumes, it is like a Barrel of Space. Kyle took it to his Pocket Dimension Storage Space. Kyle sensed that the Monkey was still alive and this time the Monkey is moving and the Time does not stop at the Pocket Space.
At that instant, Kyle left for the Game of Thrones world where he has just woken up in the Camp that the Group has built. Kyle removed the Space Pocket and saw that the Monkey is still alive and along with his Devil Fruit abilities. Kyle then took the Monkey outside and it is perfectly fine.
The Monkey tried to escape, but Kyle again captured him and took him back to One Piece world. Kyle at the exact moment with excitement said to Vegapunk " Amazing, I could even store living beings after them being captured and release them whenever I want, which means I could Capture Prisoners or Rescue people from Dangerous Situations. "
Vegapunk smiled at the result, he has already taken the readings. Vegapunk " Kyle, from this day, you have completed all the treatment and now you are in perfect control of yourself. And it is about time that you join the training in the Marine Headquarters. " Kyle " But I have just ate the Devil Fruit, don't you want to study the changes!? "
Vegapunk " No not here, you must gain Practical Experience. You are a fighter as much as you are a Researcher. It is about time you go away and continue your Journey and so you would have better growth and better data. And not to mention, I have prepared enough audio Books in the PC which you have asked that would play as Video of The Pages scrolling. It is about all formats of Scientific Study. "
Vegapunk " And you have asked me a Construction Robots, and Construction Machines so you could build a School for the Childrens in your Windmill Village right!? I have already tweaked some time and built some of the Machines for you. As long as you provide the Materials they would built you a Sturdy Building in No Time. I have also developed the Flesh Regeneration Craddle as long as you provide the necessary Ingredients. And the Fertilizers that is specifically found Boin Archipelago which makes the Soil nutritient rich even for the Desert Soil. "
Kyle was so happy when he heard it because, his trip to Essos is more than just, Vegapunk helped him built which may have just taken him some small time, Vegapunk did not question him much why, he wants to build such things but he believed it was for good of the people. As much as the boy was bloodthirsty, his ideals is always for the weak people and their empowerment, he is not a revolutionary who wants to overthrow but just want to help as much as can.
So Vegapunk did him that favour. Even Kizaru and Sentomaru bonded nice and well with Kyle who said he is knight for the weak. A Funny scene where Sentomaru was knighted by Kyle. Sentomaru calls himself a knight.
