Roy observed a battle between Benson, a Revolutionary Army member, and Gale, a Mechanical Soldier loyal to Dr. Vegapunk, while investigating the world inside the Mechanical Giant Turtle. He suspected Vegapunk was monitoring the continent and left without interfering, finding that its people were divided over whether Vegapunk was a savior or a threat.

Roy recruited Vegapunk to develop a Dream Signal Station for the Dream Web Project, a global dream platform for communication, trade, and training. Vegapunk doubted people would trust a system controlled by Roy, but Roy remained confident they would be drawn to it.

• Roy said that the Dream Net’s allure would overcome people’s fear of him and draw them back into the dreams.

Roy gave Vegapunk research materials and a Mechanical Fruit, hoping the scientist would use it to advance his work. Vegapunk accepted the fruit and reflected that technology and Devil Fruits would shape the world's future together.

• Roy gave Vegapunk two data chips, and Vegapunk dismissed most of the scientists' research while finding some value in the Lunar People data.
