The fruit’s major strength, as demonstrated by Luffy, is that the person’s body can stretch like rubber even when the ability user himself is nullified (for instance, when Nojiko pulls Luffy’s head out of the water at Arlong Park). It also makes them almost entirely immune to blunt attacks, including hand-to-hand combat, bullets or even cannonballs, an ability which can be further reinforced with the application of Busoshoku Haki.
Thanks to Luffy’s own creativity both in and out of combat, this fruit has consistently proven itself to be among the most formidable, versatile, and unpredictable within the Paramecia class. The user’s rubber-like body also allows the user to survive falls from heights and collisions that would kill a normal person.
