How the heck did Franky get 0 powerups from the most technologically advanced island on the planet? And given his extensive research into DFs, Vegapunk should’ve been able to create something better than the Rumble Balls
Lilith will work with Chopper on medicine; Franky on engineering; Brook on how the human Soul works; Robin on history; Usopp on various tech; and Nami on weather tech.
Vegapunk's Flower-Powder that turns gunpowder into flowers is more or less designed for Usopp.
Caesar was able to increase the potency of Chopper's Rumble Ball to a heavy extent, and we know Vegapunk is far superior to Caesar. This will lead into a Smile Cure/Chopper furthering his Rumble Ball technology.
And Franky obviously just wants to pull up and discuss everything science with Vegapunk.
The Egghead Arc being an escape arc prevented Vegapunk from really interacting with the crew in ways like this. Now that they have Lilith on board, they can do that stuff.
