@uniaka:
The man is right about something.
Blackbears knows about DFs, he got 2 of the best DFs in the world. I would imagine BB knows about a DF that is worth 5 billions and can make you immortal. Was also said BB hunts strong DFs.
A rubber fruit is nothing special. And the fact that the main character invented the Gears to defeat strong villains, gears are not default powers of the fruit, or are easy to learn for others.
Look at Doflamingo, likely many users would never manage to do a island size birdcage with it, and be stuck with the default 5 color strings attack lol.
Gears are the direct result of the fruits powers.. wtf are you smoking? you cant compress and speed up your blood speed for gear 2 without rubber compression. As well as you cant make your bones expand without rubber, Gear 3. And you cant make your muscles expand without rubber Gear 4….... its not like walking on air or instant speed like the vice admirals use which can be used by any who try hard to learn it...
